## Troubleshooting
|
|
|
|
### Insufficient disk space
|
|
|
|
Check available space:
|
|
```bash
|
|
ansible all -m shell -a "df -h /var/backups"
|
|
```
|
|
|
|
Clean old backups:
|
|
```bash
|
|
ansible-playbook playbooks/backup.yml --tags cleanup
|
|
```
|
|
|
|
### Database backup fails
|
|
|
|
Check database connectivity:
|
|
```bash
|
|
# MySQL
|
|
ansible all -m shell -a "mysqldump --version"
|
|
|
|
# PostgreSQL
|
|
ansible all -m shell -a "sudo -u postgres pg_dumpall --version"
|
|
```
|
|
|
|
### Backup integrity check fails
|
|
|
|
Manually verify:
|
|
```bash
|
|
ansible all -m shell -a "gzip -t /var/backups/config/*.gz"
|
|
```
|
|
|
|
## Restore from Backup
|
|
|
|
See [Disaster Recovery Playbook](disaster_recovery.md) for restoration procedures.
|
|
|
|
```bash
|
|
# Quick restore example
|
|
ansible-playbook playbooks/disaster_recovery.yml \
|
|
--limit failed_host \
|
|
--extra-vars "dr_backup_date=2025-01-11"
|
|
```
|
|
|
|
## Best Practices
|
|
|
|
1. **Test restores regularly** - Backups are useless if they can't be restored
|
|
2. **Monitor backup sizes** - Watch for unexpected growth
|
|
3. **Use remote storage** - Don't keep backups only on the same host
|
|
4. **Verify backups** - Always enable verification
|
|
5. **Document retention** - Follow compliance requirements
|
|
6. **Encrypt sensitive backups** - Use encryption for databases
|
|
7. **Schedule appropriately** - Run during low-activity periods
|
|
|
|
## Quick Reference Commands
|
|
|
|
```bash
|
|
# Full backup with verification
|
|
ansible-playbook playbooks/backup.yml \
|
|
--extra-vars "backup_type=full"
|
|
|
|
# Configuration only
|
|
ansible-playbook playbooks/backup.yml --tags config
|
|
|
|
# Databases only
|
|
ansible-playbook playbooks/backup.yml --tags databases
|
|
|
|
# Cleanup old backups (30+ days)
|
|
ansible-playbook playbooks/backup.yml --tags cleanup
|
|
|
|
# Custom retention (90 days)
|
|
ansible-playbook playbooks/backup.yml --tags cleanup \
|
|
--extra-vars "backup_retention_days=90"
|
|
|
|
# Dry-run
|
|
ansible-playbook playbooks/backup.yml --check
|
|
|
|
# Specific host only
|
|
ansible-playbook playbooks/backup.yml --limit hostname
|
|
|
|
# Production environment
|
|
ansible-playbook -i inventories/production playbooks/backup.yml
|
|
```
