3tears-backup

Encrypted, grandfather-father-son (GFS) rotated database backups to any ObjectStore, with restore verification — built on 3tears primitives so it drops into any 3tears app.

  • Storage-agnostic. The engine takes an injected ObjectStore (3tears-object-store — S3 is the first driver, filesystem the second) and streams the dump through EncryptedObjectStore, so a multi-GB dump is client-side AES-256-GCM encrypted and never sits whole in memory.
  • Postgres and Yugabyte. A pluggable DbDumpDriver wraps the right dump tool; the engine autodetects the target from version().
  • GFS retention. Keep N daily / weekly / monthly backups; prune the rest.
  • Restore-verified. Backups are proven by restoring into a throwaway temporary database, with an optional hook to spin a stack against it.

Configuration is an injected, frozen BackupConfig — construct it however you like (a from_env factory reads THREETEARS_BACKUP_* with defaults; most apps will build it from control-plane settings instead).
