"""Backup online SQLite — copie consistenta a bazei pe volum persistent.
|
|
|
|
SQLite in WAL NU se copiaza sigur cu `cp` (WAL-ul poate avea tranzactii necheckpoint-ate).
|
|
Folosim API-ul `Connection.backup` (online, consistent, fara oprirea worker-ului).
|
|
|
|
Utilizare:
|
|
python -m tools.backup # -> <db_dir>/backups/autopass-YYYYMMDD-HHMMSS.db
|
|
python -m tools.backup --out /path/snap.db # destinatie explicita
|
|
python -m tools.backup --keep 14 # pastreaza ultimele 14, sterge restul
|
|
|
|
Recomandat: rulat dintr-un cron pe gazda (ex. zilnic), tinta pe volum/montaj separat.
