Password file was being deleted on uninstall and regenerated with a new random password on reinstall +2. Repository initialization script was deleting all data in `/data` if access failed +3. Restic repositories are encrypted - wrong password = inaccessible backups + +## โœ… Changes Implemented + +### 1. **Password Persistence** (`scripts/install-restic.sh`) + +**What Changed:** +- Password is now stored in BOTH locations: + - `/etc/restic-password` (local, for immediate use) + - `/data/.restic-password` (shared storage, survives reinstalls) + +**Logic Flow:** +1. Check shared storage first (`/data/.restic-password`) +2. If found โ†’ restore to local path +3. If not found but local exists โ†’ backup to shared storage +4.
