Vaultkeeper backs up PostgreSQL, MySQL/MariaDB, MongoDB, and SQLite on a cron schedule — compressed, encrypted, shipped to disk/S3/FTP, pruned by retention policy, with instant failure alerts. SimpleBackups charges $29–$99/month ($348+/yr) to run pg_dump on a timer, with your production credentials on their cloud. Vaultkeeper is $39 once, on your own hardware.

Built for anyone running a production database who's ever found a backup script that had been failing silently for weeks.

• Four engines: pg_dump, mysqldump, mongodump, and SQLite via the online backup API (safe on live WAL databases)

• Cron scheduling with presets, per-job timezones, next-3-runs preview, and concurrent-run locks

• Streamed pipeline: dump → gzip → encrypt → destination, with size, duration, and sha256 per run

• Encryption you can restore without us: age, or documented AES-256-GCM (VK1 format) with a dependency-free decrypt script

• Destinations: local disk, any S3-compatible bucket (AWS, B2, R2, MinIO), FTP/FTPS

• GFS-lite retention: keep last N + daily-for-X-days + weekly-for-Y-weeks, auto-pruned

• Failure alerts via webhook + email, with the dump tool's stderr tail included

• Restore helper generates the exact download → decrypt → gunzip → restore command chain

Runs as a Windows desktop app or on a $5 VPS (Docker included — image bundles all four engine CLIs).

What's included:

• Windows installer download (build via npm run dist)
