**Backup Strategy:**
- **Sundays**: Full volume backup with brief downtime (keeps 2 weeks of full backups)
- **Monday-Saturday**: Online database dumps without downtime (keeps 7 days of incremental backups)
- **Sundays**: Full volume backup with brief downtime (keeps 2 full backups)
- **Monday-Saturday**: Online database dumps without downtime (keeps 6 daily backups)
- **Safety net**: The retention policy ensures that at any point you have 2 full backups plus the 6 daily dumps created between them. This provides up to 2 weeks to detect and recover from a corrupted or inconsistent full backup before losing the previous full backup and its associated daily dumps.
All backup operations are logged with timestamps:
- Volume backups: `./mongo-backup/db-backup-standalone.log`
- Database dumps: `./mongo-backup/db-dump-db-standalone.log`
- Restore operations: `./mongo-backup/db-restore-from-dump.log`
## Backup Directories
## Backup Directory
- `./mongo-backup/` - Volume backup archives (full mongo-volume directory)
- `./mongo-backup/` - Database dump archives (utility-bills database only)
All backups are stored in `./mongo-backup/`:
- Volume backups: `mongo-volume-backup-YYYY-MM-DD-HH-MM.tar.gz` (full mongo-volume directory)
- Database dumps: `utility-bills-dump-YYYY-MM-DD_HH-MM.tar.gz` (utility-bills database only)
Both directories are excluded from git via `.gitignore`.
