- **CVReyga** (476 MB): 2-5 minutes
- **Both**: 7-20 minutes

## Troubleshooting

### Backup file not found
```
Solution: Download from Google Drive and save to synced_backups/
```

### PostgreSQL connection failed
```
Solution: Ensure PostgreSQL is running
         psql -U root -l
```

### Restore is slow
```
This is normal for large databases. Let it complete.
Estimated time: 5-15 minutes per database.
```

### SQL errors during restore
```
Check backup file is complete and not corrupted.
Try syncing one database at a time.
Review error messages for specific issues.
```
