Snapshot
Time Machine
Piglet Run provides point-in-time recovery for both database and filesystem.
Database PITR
PostgreSQL’s built-in PITR (Point-in-Time Recovery) allows you to restore the database to any point in time. Managed by pgBackRest.
# Show backup information
pig pb info
# List all backups
pig pb ls
# Create a full backup
pig pb backup full
# Restore to latest backup
pig pb restore
# Restore to specific time
pig pb restore -t "2025-01-29 10:00:00"
Filesystem Snapshots
JuiceFS snapshots preserve the state of your workspace:
# Create a snapshot (using juicefs CLI)
juicefs snapshot create /jfs/data snapshot-before-experiment
# List snapshots
juicefs snapshot list /jfs/data
# Restore from snapshot
juicefs snapshot restore /jfs/data snapshot-before-experiment
Use Cases
| Scenario | Solution |
|---|---|
| AI broke code | Restore filesystem snapshot |
| Bad database migration | Use pig pb restore -t <time> |
| Experiment failed | Roll back entire environment |
| Need clean state | Restore to baseline snapshot |
