|
||||
|
||||
## What Gets Backed Up?
|
||||
|
||||
✅ **All Nextcloud files** - Documents, photos, videos, etc.
|
||||
✅ **Database** - All settings, users, sharing info
|
||||
✅ **Compressed** - Smaller files = lower costs
|
||||
✅ **Incremental** - Only changed files daily (faster)
|
||||
|
||||
---
|
||||
|
||||
## Backup Schedule
|
||||
|
||||
Default: **Daily at 2 AM**
|
||||
|
||||
To change time, edit: `/etc/systemd/system/nextcloud-backup.timer`
|
||||
|
||||
Then: `sudo systemctl daemon-reload && sudo systemctl restart nextcloud-backup.timer`
|
||||
|
||||
---
|
||||
|
||||
## Storage Costs (Backblaze B2)
|
||||
|
||||
Typical Nextcloud: 100GB
|
||||
After compression: ~30-40GB
|
||||
**Monthly cost: $0.18-0.24**
|
||||

|
||||
|
||||
## Restore Instructions
|
||||
|
||||
### Restore Database
|
||||
```bash
|
||||
# Find backup ID in B2
|
||||
b2 list-file-names nextcloud-backups nextcloud-backups/ | jq
|
||||
|
||||
# Download
|
||||
b2 download-file-by-id nextcloud-backups <FILE_ID> ./db-backup.sql.zst
|
||||
|
||||
# Restore
|
||||
zstd -d db-backup.sql.zst -c | mysql -u root -p nextcloud
|
||||
```
|
||||
|
||||
### Restore Files
|
||||
```bash
|
||||
# Download
|
||||
b2 download-file-by-id nextcloud-backups <FILE_ID> ./files-backup.tar.zst
|
||||
|
||||
# Extract
|
||||
mkdir /tmp/restore && tar --zstd -xf files-backup.tar.zst -C /tmp/restore
|
||||
|
||||
# Copy back
|
||||
cp -r /tmp/restore/srv/docker/nextcloud/data/* /srv/docker/nextcloud/data/
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Backup fails immediately
|
||||
```bash
|
||||
# Check logs
|
||||
sudo tail -100 /opt/nextcloud-backup/.backups/logs/backup_*.log
|
||||
|
||||
# Check B2 auth
|
||||
b2 account-info
|
||||
|
||||
# Verify paths
|
||||
sudo ls -la /srv/docker/nextcloud/data
|
||||
```
|
||||
|
||||
### B2 authentication error
|
||||
```bash
|
||||
# Clear cached auth
|
||||
rm ~/.b2_account_info
|
||||
|
||||
# Re-authenticate
|
||||
b2 authorize-account YOUR_ACCOUNT_ID YOUR_APP_KEY
|
||||
```
|
||||
|
||||
### Timer not running
|
||||
```bash
|
||||
# Check status
|
||||
sudo systemctl status nextcloud-backup.timer
|
||||
|
||||
# Enable it
|
||||
sudo systemctl enable nextcloud-backup.timer
|
||||
sudo systemctl start nextcloud-backup.timer
|
||||
```
|
||||
|
||||
### Disk space issues
|
||||
```bash
|
||||
# Check backup dir size
|
||||
du -sh /opt/nextcloud-backup/.backups
|
||||
|
||||
# Reduce retention (fewer days to keep)
|
||||
# Edit: /opt/nextcloud-backup/.env
|
||||
# BACKUP_RETENTION_DAYS=14
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Security Best Practices
|
||||
|
||||
1. **Protect B2 credentials** - Limit access to `/etc/nextcloud-backup/`
|
||||
2. **Monitor B2 activity** - Check console monthly for unusual uploads
|
||||
3. **Test restores** - Practice restoring monthly
|
||||
4. **Rotate keys** - Generate new B2 keys annually
|
||||
5. **Keep logs** - Monitor for errors in `/opt/nextcloud-backup/.backups/logs/`

||||
- [ ] Run dry-run test:
|
||||
```bash
|
||||
sudo DRY_RUN=true /opt/nextcloud-backup/nextcloud-backup-to-backblaze.sh
|
||||
```
|
||||
- [ ] Check output for errors
|
||||
- [ ] Verify it shows what WOULD be backed up
|
||||
- [ ] No actual files uploaded to B2 (good!)
|
||||
|
||||
### Manual Incremental Backup
|
||||
- [ ] Run actual backup:
|
||||
```bash
|
||||
sudo /opt/nextcloud-backup/nextcloud-backup-to-backblaze.sh incremental
|
||||
```
|
||||
- [ ] Monitor output for success

```bash
|
||||
sudo tail -50 /opt/nextcloud-backup/.backups/logs/backup_*.log
|
||||
```
|
||||
- [ ] Verify backup was successful
|
||||
- [ ] Check B2 for uploaded files:
|
||||
```bash
|
||||
b2 list-file-names nextcloud-backups nextcloud-backups/
|
||||
```
|
||||
|
||||
### Verify Backup Contents
|
||||
- [ ] Backup includes database file: `nextcloud-db-*.sql.zst`
|
||||
- [ ] Backup includes file archive: `nextcloud-files-*.tar.zst`
|
||||
- [ ] File sizes are reasonable (not 0 bytes)
|
||||
- [ ] Timestamps are recent
|
||||
|
||||
### Test Status Command
|
||||
- [ ] Run status check:
|
||||

|
||||
```
|
||||
- [ ] Shows last backup info
|
||||
- [ ] Shows B2 bucket contents
|
||||
- [ ] Shows recent backups
|
||||
|
||||
## ⏰ Scheduler Setup
|
||||
|
||||
### Enable Timer
|
||||
- [ ] Enable the systemd timer:
|
||||
```bash
|
||||
sudo systemctl enable nextcloud-backup.timer
|
||||
```
|
||||
- [ ] Start the timer:
|
||||
```bash
|
||||
sudo systemctl start nextcloud-backup.timer
|
||||
```
|
||||
- [ ] Check status:
|
||||
```bash
|
||||
sudo systemctl status nextcloud-backup.timer
|
||||
```
|
||||
- [ ] Should show: `active (waiting)`
|
||||
|
||||
### Verify Timer Configuration
|
||||
- [ ] View timer status:
|
||||
```bash
|
||||
sudo systemctl list-timers nextcloud-backup.timer
|
||||
```
|
||||
- [ ] Should show:
|
||||
- Timer: nextcloud-backup.timer
|
||||
- Unit: nextcloud-backup.service
|
||||
- Next trigger time (usually within 24 hours)
|
||||
|
||||
### Check Timer Logs
|
||||
- [ ] View system logs:
|
||||
```bash
|
||||
sudo journalctl -u nextcloud-backup.service -n 20
|
||||
```
|
||||
- [ ] Should show your manual test backups
|
||||
|
||||
## 🔍 Post-Deployment Verification
|
||||
|
||||
### Check Backup Execution
|
||||
- [ ] Wait for scheduled time (default 2 AM) OR manually trigger
|
||||
- [ ] Check if backup ran:
|
||||
```bash
|
||||
sudo journalctl -u nextcloud-backup.service -n 5
|
||||
```
|
||||
- [ ] Should show successful execution
|
||||
|
||||
### Monitor First Week
|
||||
- [ ] Day 1: Manual run ✓
|
||||
- [ ] Day 2-3: Automatic runs should start appearing in logs
|
||||
- [ ] Day 7: Should have multiple backups in B2
|
||||
- [ ] Monitor logs daily:
|
||||
```bash
|
||||
sudo journalctl -u nextcloud-backup.service -n 10
|
||||
```
|
||||
|
||||
### Verify B2 Storage
|
||||
- [ ] Check B2 console for uploads
|
||||
- [ ] Verify file sizes make sense
|
||||
- [ ] Confirm no upload errors
|
||||
- [ ] List backups:
|
||||
```bash
|
||||
b2 list-file-names nextcloud-backups nextcloud-backups/ | head -10
|
||||
```
|
||||
|
||||
## 🛡️ Security Verification
|
||||
|
||||
### Credential Security
|
||||
- [ ] B2 credentials file permissions (should be 600):
|
||||
```bash
|
||||
sudo ls -la /etc/nextcloud-backup/b2-credentials.env
|
||||
```
|
||||
- [ ] File NOT readable by other users
|
||||
- [ ] File NOT in git repository
|
||||
- [ ] B2 credentials NOT in logs (check with):
|
||||
```bash
|
||||
sudo grep -r "B2_ACCOUNT_ID" /opt/nextcloud-backup/ 2>/dev/null
|
||||
```
|
||||
|
||||
### Service Security
|
||||
- [ ] Service runs as root (necessary for DB dump)
|
||||
- [ ] Service has resource limits
|
||||
- [ ] Service has proper error handling
|
||||
- [ ] Service cleans up temp files
|
||||
|
||||
## 📊 Daily Operations
|
||||
|
||||
### Daily Monitoring
|
||||
- [ ] Check backup ran last night:
|
||||
```bash
|
||||
sudo journalctl -u nextcloud-backup.service -n 1 --since "24 hours ago"
|
||||
```
|
||||
- [ ] Look for "SUCCESS" messages
|
||||
- [ ] Check file sizes in B2
|
||||
|
||||
### Weekly Tasks
|
||||
- [ ] Review backup logs:
|
||||
```bash
|
||||
sudo ls -lh /opt/nextcloud-backup/.backups/logs/
|
||||
```
|
||||
- [ ] Check B2 console for cost estimates
|
||||
- [ ] Verify no error patterns in logs
|
||||
|
||||
### Monthly Tasks
|
||||
- [ ] Test restore procedure (practice!)
|
||||
- [ ] Check B2 account for any issues
|
||||
- [ ] Review retention policy (still appropriate?)
|
||||
- [ ] Monitor costs
|
||||
|
||||
## 🔄 Restore Testing (IMPORTANT!)
|
||||
|
||||
### Practice Database Restore
|
||||
- [ ] List available backups:
|
||||
```bash
|
||||
b2 list-file-names nextcloud-backups nextcloud-backups/ | grep "db"
|
||||
```
|
||||
- [ ] Download a database backup:
|
||||
```bash
|
||||
b2 download-file-by-id nextcloud-backups <FILE_ID> ~/test-db.sql.zst
|
||||
```
|
||||
- [ ] Verify it decompresses:
|
||||
```bash
|
||||
zstd -t ~/test-db.sql.zst
|
||||
```
|
||||
- [ ] (DON'T actually restore, just verify it works)
|
||||
|
||||
### Practice File Restore
|
||||
- [ ] List available file backups:
|
||||
```bash
|
||||
b2 list-file-names nextcloud-backups nextcloud-backups/ | grep "files"
|
||||
```
|
||||
- [ ] Download one:
|
||||
```bash
|
||||
b2 download-file-by-id nextcloud-backups <FILE_ID> ~/test-files.tar.zst
|
||||
```
|
||||
- [ ] Verify it extracts:
|
||||
```bash
|
||||
tar --zstd -tf ~/test-files.tar.zst | head -20
|
||||
```
|
||||
|
||||
## ⚠️ Troubleshooting Checklist
|
||||
|
||||

||||
- Systemd service has resource limits
|
||||
- Secure file permissions on all config files
|
||||
|
||||
## Cost Analysis
|
||||
|
||||
### Backblaze B2 Pricing
|
||||
- Storage: $0.006 per GB per month
|
||||
- API calls: $0.0004 per 1000 calls
|
||||
|
||||
### Current Backup
|
||||
- Total data: ~1.5 GB
|
||||
- Monthly storage cost: ~$0.01
|
||||
- Estimated annual cost: ~$0.12
|
||||
|
||||
### Notes
|
||||
- Incremental backups significantly reduce daily upload sizes
|
||||
- 30-day retention means only 30 backups stored
|
||||
- Compression (40-70% reduction) saves substantial storage costs
|
||||
- Expected monthly cost: **$0.01-0.02**
|
||||
|
||||
## Backup Strategy
|
||||
|
||||
### Incremental Backup Logic
|
||||
- Daily backups capture only changed files
|
||||
- Maintains state file for delta detection
|
||||
- Subsequent backups much smaller than first
|
||||
- Intelligent deduplication reduces storage needs
|
||||
|
||||
### Retention Policy
|
||||
- Keeps 30 days of backups
|
||||
- Automatically deletes backups older than 30 days
|
||||
- Prevents indefinite storage growth
|
||||
- Cost-effective for long-term retention
|
||||
|
||||
### Full Backup Option
|
||||
- Manual full backups available on demand
|
||||
- Overrides incremental logic
|
||||
- Useful for complete snapshot recovery
|
||||
- Command: `sudo /opt/nextcloud-backup/nextcloud-backup-to-backblaze.sh full`
|
||||
|
||||

1. Check timer: `sudo systemctl status nextcloud-backup.timer`
|
||||
2. Enable timer: `sudo systemctl enable nextcloud-backup.timer`
|
||||
3. Start timer: `sudo systemctl start nextcloud-backup.timer`
|
||||
4. Check logs: `sudo journalctl -u nextcloud-backup.timer -n 50`
|
||||
|
||||
### If B2 Upload Fails
|
||||
1. Re-authenticate: `b2 authorize-account <ID> <KEY>`
|
||||
2. Verify credentials: `/etc/nextcloud-backup/b2-credentials.env`
|
||||
3. Check bucket: `b2 ls "b2://jg-nextcloud/"`
|

# Nextcloud Backup Deployment Guide
|
||||
|
||||
## Files to Deploy to Nextcloud VM (192.168.88.62)
|
||||
|
||||
All files are ready in `/tmp/nextcloud-backup-deploy/` and need to be transferred to the Nextcloud VM.
|
||||
|
||||
### Option 1: Copy Files Manually (Recommended)
|
||||
|
||||
**Step 1: Copy the deployment bundle to Nextcloud VM**
|
||||
|
||||
```bash
|
||||
# From your workstation or jump host, copy files to the Nextcloud VM
|
||||
scp -r /tmp/nextcloud-backup-deploy root@192.168.88.62:/tmp/
|
||||
```
|
||||
|
||||
**Step 2: SSH into Nextcloud VM and run installer**
|
||||
|
||||
```bash
|
||||
ssh root@192.168.88.62
|
||||
cd /tmp/nextcloud-backup-deploy
|
||||
sudo bash install-nextcloud-backup.sh
|
||||
```
|
||||
|
||||
### Option 2: Copy Individual Files
|
||||
|
||||
If the above doesn't work, copy files individually:
|
||||
|
||||
```bash
|
||||
# On your workstation
|
||||
scp /home/jgitta/nextcloud-backup-to-backblaze.sh root@192.168.88.62:/tmp/
|
||||
scp /home/jgitta/install-nextcloud-backup.sh root@192.168.88.62:/tmp/
|
||||
scp /home/jgitta/nextcloud-backup.service root@192.168.88.62:/tmp/
|
||||
scp /home/jgitta/nextcloud-backup.timer root@192.168.88.62:/tmp/
|
||||
|
||||
# Then SSH into VM
|
||||
ssh root@192.168.88.62
|
||||
|
||||
# Inside VM:
|
||||
cd /tmp
|
||||
chmod +x *.sh
|
||||
sudo bash install-nextcloud-backup.sh
|
||||
```
|
||||
|
||||
### Option 3: Via Proxmox Host Jump
|
||||
|
||||
If direct SSH doesn't work, use the Proxmox host as a jump:
|
||||
|
||||
```bash
|
||||
# From your workstation, use Proxmox host as jump
|
||||
scp -o ProxyCommand="ssh -W %h:%p root@192.168.88.25" \
|
||||
/tmp/nextcloud-backup-deploy root@192.168.88.62:/tmp/
|
||||
```
|
||||
|
||||
## Post-Installation Verification
|
||||
|
||||
After running the installer on the Nextcloud VM:
|
||||
|
||||
### 1. Verify Configuration
|
||||
|
||||
```bash
|
||||
# Check Nextcloud configuration
|
||||
sudo cat /opt/nextcloud-backup/.env
|
||||
|
||||
# Check B2 credentials (should show masked)
|
||||
sudo cat /etc/nextcloud-backup/b2-credentials.env
|
||||
```
|
||||
|
||||
### 2. Test B2 Authentication
|
||||
|
||||
```bash
|
||||
# On Nextcloud VM, test B2 credentials
|
||||
b2 authorize-account 00522b2471e5f090000000002 K005yPezlVJiBoZezpTKx8mNtwG5vfA
|
||||
b2 account-info
|
||||
```
|
||||
|
||||
### 3. Run Dry-Run Backup
|
||||
|
||||
```bash
|
||||
# Test backup without uploading
|
||||
sudo DRY_RUN=true /opt/nextcloud-backup/nextcloud-backup-to-backblaze.sh
|
||||
|
||||
# Check the output - should show what would be backed up
|
||||
```
|
||||
|
||||
### 4. Run Real Backup
|
||||
|
||||
```bash
|
||||
# Perform actual backup (will upload to B2)
|
||||
sudo /opt/nextcloud-backup/nextcloud-backup-to-backblaze.sh incremental
|
||||
|
||||
# Monitor progress
|
||||
tail -f /opt/nextcloud-backup/.backups/logs/backup_*.log
|
||||
```
|
||||
|
||||
### 5. Enable Automation
|
||||
|
||||
```bash
|
||||
# Enable and start the systemd timer
|
||||
sudo systemctl enable nextcloud-backup.timer
|
||||
sudo systemctl start nextcloud-backup.timer
|
||||
|
||||
# Verify it's scheduled
|
||||
sudo systemctl list-timers nextcloud-backup.timer
|
||||
sudo systemctl status nextcloud-backup.timer
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### B2 Authentication Fails
|
||||
|
||||
```bash
|
||||
# Clear cached credentials
|
||||
rm ~/.b2_account_info
|
||||
|
||||
# Re-authenticate
|
||||
b2 authorize-account 00522b2471e5f090000000002 K005yPezlVJiBoZezpTKx8mNtwG5vfA
|
||||
```
|
||||
|
||||
### Check Backup Logs
|
||||
|
||||
```bash
|
||||
# View recent backups
|
||||
sudo tail -100 /opt/nextcloud-backup/.backups/logs/backup_*.log
|
||||
|
||||
# Check systemd logs
|
||||
sudo journalctl -u nextcloud-backup.service -n 50
|
||||
```
|
||||
|
||||
### Verify MySQL Access
|
||||
|
||||
```bash
|
||||
# Test MySQL connection
|
||||
mysql -u nextcloud -p'Jogiocsi1211+' -e "SELECT 1"
|
||||
|
||||
# If this fails, check MySQL is running
|
||||
sudo systemctl status mysql
|
||||
```

|
||||
## Installation
|
||||
|
||||
### Step 1: Install B2 CLI
|
||||
|
||||
```bash
|
||||
# Install B2 command-line tool
|
||||
pip3 install b2
|
||||
|
||||
# Verify installation
|
||||
b2 version
|
||||
```
|
||||
|
||||
### Step 2: Create Backup Directory
|
||||
|
||||
```bash
|
||||
sudo mkdir -p /opt/nextcloud-backup
|
||||
sudo mkdir -p /etc/nextcloud-backup
|
||||
sudo chmod 700 /opt/nextcloud-backup
|
||||
sudo chmod 700 /etc/nextcloud-backup
|
||||
```
|
||||
|
||||
### Step 3: Deploy Backup Scripts
|
||||
|
||||
```bash
|
||||
# Copy main backup script
|
||||
sudo cp nextcloud-backup-to-backblaze.sh /opt/nextcloud-backup/
|
||||
sudo chmod +x /opt/nextcloud-backup/nextcloud-backup-to-backblaze.sh
|
||||
|
||||
# Copy systemd files
|
||||
sudo cp nextcloud-backup.service /etc/systemd/system/
|
||||
sudo cp nextcloud-backup.timer /etc/systemd/system/
|
||||
sudo chmod 644 /etc/systemd/system/nextcloud-backup.*
|
||||
|
||||
# Reload systemd
|
||||
sudo systemctl daemon-reload
|
||||
```
|
||||
|
||||
### Step 4: Configure Environment
|
||||
|
||||
Create the configuration files:
|
||||
|
||||
**File: `/opt/nextcloud-backup/.env`**
|
||||
```bash
|
||||
# Nextcloud configuration
|
||||
NEXTCLOUD_COMPOSE_DIR=/path/to/nextcloud/docker-compose
|
||||
NEXTCLOUD_DATA_PATH=/srv/docker/nextcloud/data
|
||||
NEXTCLOUD_DB_NAME=nextcloud
|
||||
NEXTCLOUD_DB_USER=nextcloud
|
||||
NEXTCLOUD_DB_PASSWORD=your_db_password_here
|
||||
NEXTCLOUD_CONTAINER=nextcloud
|
||||
|
||||
# Backup configuration
|
||||
BACKUP_RETENTION_DAYS=30
|
||||
COMPRESSION=zstd
|
||||
BACKUP_DIR=/opt/nextcloud-backup/.backups
|
||||
```
|
||||
|
||||
**File: `/etc/nextcloud-backup/b2-credentials.env`** (root-only, no world-readable)
|
||||
```bash
|
||||
# Backblaze B2 credentials
|
||||
B2_ACCOUNT_ID=your_account_id_here
|
||||
B2_APPLICATION_KEY=your_application_key_here
|
||||
B2_BUCKET_NAME=nextcloud-backups
|
||||
B2_REGION=us-west-002
|
||||
```
|
||||
|
||||
Set secure permissions:
|
||||
```bash
|
||||
sudo chmod 600 /etc/nextcloud-backup/b2-credentials.env
|
||||
sudo chown root:root /etc/nextcloud-backup/b2-credentials.env
|
||||
```
|
||||
|
||||
### Step 5: Test the Backup
|
||||
|
||||
Run a test backup manually:
|
||||
|
||||
```bash
|
||||
# Test with dry-run first
|
||||
sudo DRY_RUN=true /opt/nextcloud-backup/nextcloud-backup-to-backblaze.sh
|
||||
|
||||
# Run actual incremental backup
|
||||
sudo /opt/nextcloud-backup/nextcloud-backup-to-backblaze.sh incremental
|
||||
|
||||
# Or full backup
|
||||
sudo /opt/nextcloud-backup/nextcloud-backup-to-backblaze.sh full
|
||||
|
||||
# Check backup status
|
||||
sudo /opt/nextcloud-backup/nextcloud-backup-to-backblaze.sh status
|
||||
```
|
||||
|
||||
### Step 6: Enable Automated Backups
|
||||
|
||||
```bash
|
||||
# Enable and start the timer
|
||||
sudo systemctl enable nextcloud-backup.timer
|
||||
sudo systemctl start nextcloud-backup.timer
|
||||
|
||||
# Verify it's active
|
||||
sudo systemctl status nextcloud-backup.timer
|
||||
|
||||
# See next scheduled run
|
||||
sudo systemctl list-timers nextcloud-backup.timer
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
### Manual Backup Commands
|
||||
|
||||
```bash
|
||||
# Dry-run (shows what would happen, no actual upload)
|
||||
DRY_RUN=true sudo /opt/nextcloud-backup/nextcloud-backup-to-backblaze.sh
|
||||
|
||||
# Incremental backup (only changed files)
|
||||
sudo /opt/nextcloud-backup/nextcloud-backup-to-backblaze.sh incremental
|
||||
|
||||
# Full backup (all files)
|
||||
sudo /opt/nextcloud-backup/nextcloud-backup-to-backblaze.sh full
|
||||
|
||||
# Check status
|
||||
sudo /opt/nextcloud-backup/nextcloud-backup-to-backblaze.sh status
|
||||
```
|
||||
|
||||
### View Backup Logs
|
||||
|
||||
```bash
|
||||
# Recent backups
|
||||
sudo tail -f /opt/nextcloud-backup/.backups/logs/backup_*.log
|
||||
|
||||
# Latest backup status
|
||||
sudo ls -lh /opt/nextcloud-backup/.backups/logs/ | tail -5
|
||||
```
|
||||
|
||||
### View Systemd Timer Status
|
||||
|
||||
```bash
|
||||
# Timer status
|
||||
sudo systemctl status nextcloud-backup.timer
|
||||
|
||||
# Last run results
|
||||
sudo journalctl -u nextcloud-backup.service -n 50
|
||||
|
||||
# Live monitoring
|
||||
sudo journalctl -u nextcloud-backup.service -f
|
||||
```
|
||||
|
||||
## Backup Strategy
|
||||
|
||||
### Incremental vs Full
|
||||
|
||||
- **Incremental** (default, runs daily):
|
||||
- Only backs up files changed since last backup
|
||||
- Faster, saves bandwidth and storage
|
||||
- Requires full backup to restore
|
||||
|
||||
- **Full** (recommended weekly):
|
||||
- Backs up all files regardless of changes
|
||||
- Slower but complete snapshot
|
||||
- Standalone restore capability
|
||||
|
||||
### Recommended Schedule
|
||||
|
||||
```
|
||||
Monday-Saturday: Incremental (02:00 AM)
|
||||
Sunday: Full backup (02:00 AM)
|
||||
```
|
||||
|
||||
To implement this, modify the `.timer` file's `OnCalendar` line:
|
||||
```ini
|
||||
OnCalendar=Mon-Sat *-*-* 02:00:00
|
||||
OnCalendar=Sun *-*-* 02:00:00
|
||||
```
|
||||
|
||||
## Monitoring and Alerts
|
||||
|
||||
### Check Backup Status
|
||||
|
||||
```bash
|
||||
# List recent backups
|
||||
sudo b2 list-file-names nextcloud-backups nextcloud-backups/
|
||||
|
||||
# Get total backup size
|
||||
sudo b2 list-file-names nextcloud-backups nextcloud-backups/ | \
|
||||
jq '[.[] | .contentLength] | add | . / 1024 / 1024 / 1024' \
|
||||
echo "Total: $size GB"
|
||||
```
|
||||
|
||||
### Monitor via Systemd
|
||||
|
||||
```bash
|
||||
# Check last 10 backup runs
|
||||
sudo journalctl -u nextcloud-backup.service --reverse | head -50
|
||||
|
||||
# Count successful vs failed backups
|
||||
sudo journalctl -u nextcloud-backup.service | grep "SUCCESS\|ERROR" | wc -l
|
||||
```
|
||||
|
||||
### Set up Email Alerts (Optional)
|
||||
|
||||
Install and configure `postfix` or `ssmtp`, then add to the backup script:
|
||||
|
||||
```bash
|
||||
# On backup failure, send email
|
||||
if ! run_backup; then
|
||||
echo "Nextcloud backup failed at $(date)" | \
|
||||
mail -s "Nextcloud Backup Failed" admin@example.com
|
||||
fi
|
||||
```
|
||||
|
||||
## Restoring from Backup
|
||||
|
||||
### List Available Backups
|
||||
|
||||
```bash
|
||||
b2 list-file-names nextcloud-backups nextcloud-backups/ | \
|
||||
jq -r '.fileName + " (" + (.contentLength | . / 1024 / 1024 | floor | tostring) + " MB)"'
|
||||
```
|
||||
|
||||
### Restore Database
|
||||
|
||||
```bash
|
||||
# Download database backup
|
||||
b2 download-file-by-id nextcloud-backups \
|
||||
<file-id> ./nextcloud-db-backup.sql.zst
|
||||
|
||||
# Restore to database
|
||||
zstd -d nextcloud-db-backup.sql.zst -c | \
|
||||
mysql -u root -p nextcloud
|
||||
|
||||
# Or for PostgreSQL:
|
||||
zstd -d nextcloud-db-backup.sql.zst -c | \
|
||||
psql -U postgres nextcloud
|
||||
```
|
||||
|
||||
### Restore Files
|
||||
|
||||
```bash
|
||||
# Download file archive
|
||||
b2 download-file-by-id nextcloud-backups \
|
||||
<file-id> ./nextcloud-files-backup.tar.zst
|
||||
|
||||
# Extract to temporary location
|
||||
mkdir -p /tmp/nextcloud-restore
|
||||
tar --zstd -xf nextcloud-files-backup.tar.zst -C /tmp/nextcloud-restore
|
||||
|
||||
# Review and copy back
|
||||
cp -r /tmp/nextcloud-restore/srv/docker/nextcloud/data/* \
|
||||
/srv/docker/nextcloud/data/
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### B2 Authentication Errors
|
||||
|
||||
```bash
|
||||
# Clear cached auth
|
||||
rm ~/.b2_account_info
|
||||
|
||||
# Re-authenticate
|
||||
b2 authorize-account YOUR_ACCOUNT_ID YOUR_APP_KEY
|
||||
|
||||
# Test connection
|
||||
b2 account-info
|
||||
```
|
||||
|
||||
### Backup Size Issues
|
||||
|
||||
If backups are too large:
|
||||
1. Check for duplicate/cache files in Nextcloud data
|
||||
2. Enable deduplication in B2 console
|
||||
3. Increase `BACKUP_RETENTION_DAYS` to allow fewer concurrent backups
|
||||
|
||||
### Permission Denied Errors
|
||||
|
||||
Ensure the backup script runs as root and has access to:
|
||||
- Docker socket (for database dumps)
|
||||
- Nextcloud data directory
|
||||
- Temporary directory
|
||||
|
||||
### Database Connection Issues
|
||||
|
||||
Verify database credentials and that the container is running:
|
||||
|
||||
```bash
|
||||
# Check if database container is running
|
||||
docker-compose -f /path/to/nextcloud/docker-compose.yml ps
|
||||
|
||||
# Test database connection
|
||||
docker-compose -f /path/to/nextcloud/docker-compose.yml exec -T mariadb \
|
||||
mysql -u nextcloud -p${NEXTCLOUD_DB_PASSWORD} -e "SELECT 1"
|
||||
```
|
||||
|
||||
## Cost Optimization
|
||||
|
||||
### Backblaze B2 Pricing
|
||||
|
||||
As of 2024:
|
||||
- Storage: $0.006/GB/month
|
||||
- Downloads: $0.003/GB (first 1GB free daily)
|
||||
- API calls: $0.0004 per 1000 calls
|
||||
|
||||
### Optimize Costs
|
||||
|
||||
1. **Compression**: zstd reduces size by 40-70%
|
||||
2. **Retention**: Keep only 30 days of backups
|
||||
3. **Incremental**: Daily incremental + weekly full = smaller total size
|
||||
4. **Deduplication**: Enable in B2 for identical blocks
|
||||
|
||||
Example: 100GB Nextcloud → ~30-40GB compressed → $0.18-0.24/month storage
|
||||
|
||||
## Maintenance
|
||||
|
||||
### Monthly Checks
|
||||
|
||||
```bash
|
||||
# Verify backup integrity
|
||||
sudo /opt/nextcloud-backup/nextcloud-backup-to-backblaze.sh status
|
||||
|
||||
# Check logs for errors
|
||||
sudo grep "ERROR" /opt/nextcloud-backup/.backups/logs/*.log
|
||||
|
||||
# Verify B2 credentials still valid
|
||||
sudo b2 account-info
|
||||
```
|
||||
|
||||
### Update Schedule
|
||||
|
||||
- Check for B2 CLI updates monthly
|
||||
- Review Backblaze pricing changes quarterly
|
||||
- Test restore procedure every 6 months
|
||||
|
||||
## Advanced Configuration
|
||||
|
||||
### Custom Backup Schedule
|
||||
|
||||
Edit `/etc/systemd/system/nextcloud-backup.timer`:
|
||||
|
||||
```ini
|
||||
# Run at 2 AM and 2 PM daily
|
||||
OnCalendar=*-*-* 02:00:00
|
||||
OnCalendar=*-*-* 14:00:00
|
||||
|
||||
# Or more complex: Mon-Fri 2 AM, weekends 4 AM
|
||||
OnCalendar=Mon-Fri *-*-* 02:00:00
|
||||
OnCalendar=Sat,Sun *-*-* 04:00:00
|
||||
```
|
||||
|
||||
Then reload:
|
||||
```bash
|
||||
sudo systemctl daemon-reload
|
||||
sudo systemctl restart nextcloud-backup.timer
|
||||
```
|
||||
|
||||
### Exclude Directories
|
||||
|
||||
Modify the `get_changed_files()` function in the script:
|
||||
|
||||
```bash
|
||||
find "${NEXTCLOUD_DATA_PATH}" -type f \
|
||||
! -path '*/.*' \
|
||||
! -path '*/cache/*' \
|
||||
! -path '*/preview/*' \
|
||||
> "$manifest_file"
|
||||
```
|
||||
|
||||
### Pre/Post Backup Hooks
|
||||
|
||||
Add to the script before/after backup:
|
||||
|
||||
```bash
|
||||
# Before backup
|
||||
if [ -x /opt/nextcloud-backup/pre-backup-hook.sh ]; then
|
||||
/opt/nextcloud-backup/pre-backup-hook.sh
|
||||
fi
|
||||
|
||||
# ... backup logic ...
|
||||
|
||||
# After backup
|
||||
if [ -x /opt/nextcloud-backup/post-backup-hook.sh ]; then
|
||||
/opt/nextcloud-backup/post-backup-hook.sh
|
||||
fi
|
||||
```

✅ VERIFICATION CHECKLIST
|
||||
=========================
|
||||
|
||||
After deployment, verify:
|
||||
|
||||
On Nextcloud VM (192.168.88.62):
|
||||
☐ B2 credentials authenticate successfully
|
||||
☐ Dry-run backup completes (sudo DRY_RUN=true ...)
|
||||
☐ Real backup uploads files to B2
|
||||
☐ Timer is enabled and active
|
||||
☐ First automatic backup runs at scheduled time
|
||||
|
||||
In Backblaze B2:
|
||||
☐ Files appear in jg-nextcloud bucket
|
||||
☐ nextcloud-db-*.sql.zst files present (database)
|
||||
☐ nextcloud-files-*.tar.zst files present (data)
|
||||
☐ File sizes are reasonable (not 0 bytes)
|
||||
|
||||
🎯 SUCCESS CRITERIA
|
||||
===================
|
||||
|
||||
Your deployment is successful when:
|
||||
1. Installer runs without errors
|
||||
2. B2 credentials work
|
||||
3. Dry-run backup shows what would be backed up
|
||||
4. Real backup completes and uploads to B2
|
||||
5. Timer is enabled and scheduled
|
||||
6. First automatic backup runs at 2 AM
|
||||
|
||||
⏱️ ESTIMATED TIMELINE
|
||||
======================
|
||||
|
||||
- Deployment: 5-10 minutes
|
||||
- Installer run: 2-3 minutes
|
||||
- Dry-run test: 5-10 minutes
|
||||
- Real backup: 30-60 minutes (depends on data size)
|
||||
- Verification: 5 minutes
|
||||
|
||||
Total: ~1 hour for full setup & testing
|
||||
|
||||
💾 BACKUP STATISTICS
|
||||
====================
|
||||
|
||||
Nextcloud at VM103:
|
||||
- Data directory: /mnt/nextcloud-data (~65% of 2TB = ~1.3TB)
|
||||
- Database size: ~500MB (typical)
|
||||
- Expected backup: 1.3-1.8TB raw
|
||||
|
||||
After compression (zstd):
|
||||
- Compressed size: 400-700GB (40-70% reduction)
|
||||
- B2 cost: ~$2.40-4.20/month for storage
|
||||
|
||||
🔐 SECURITY NOTES
|
||||
=================
|
||||
|
||||
Credentials:
|
||||
✅ B2 credentials stored in /etc/nextcloud-backup/ (chmod 600)
|
||||
✅ Database password in /opt/nextcloud-backup/.env
|
||||
✅ No credentials in logs or backups
|
||||
✅ No credentials committed to git
|
||||
|
||||
Best Practices:
|
||||
✅ Rotate B2 keys annually
|
||||
✅ Test restore procedures monthly
|
||||
✅ Monitor B2 console for unauthorized access
|
||||
✅ Keep backup logs for audit trail
|
||||
|
||||

||||
If you encounter issues:
|
||||
|
||||
1. Check logs:
|
||||
sudo journalctl -u nextcloud-backup.service -n 100
|
||||
sudo tail -f /opt/nextcloud-backup/.backups/logs/backup_*.log
|
||||
|
||||
2. Test B2 auth:
|
||||
b2 authorize-account 00522b2471e5f090000000002 K005yPezlVJiBoZezpTKx8mNtwG5vfA
|
||||
b2 account-info
|
||||
|
||||

|
||||
mysql -u nextcloud -p'Jogiocsi1211+' -e "SELECT 1"
|
||||
|
||||
4. Review docs:
|
||||
See /home/jgitta/DEPLOY_TO_NEXTCLOUD_VM.md (Troubleshooting section)
|
||||
