What It Does

Details

Performs PostgreSQL database backups using pg_basebackup and stores them on BTRFS filesystem. Uses dduper to deduplicate backup data at block level, minimizing storage requirements for consecutive backups.

Who It's For

Best fit users

  • Database administrators
  • Self-hosting teams
  • PostgreSQL users with storage constraints
Why It Matters

Why this one made the cut

Backup storage can rapidly consume disk space, especially for databases with frequent small changes. pgdedup reduces storage overhead by only storing unique data blocks across backup snapshots.

Differentiator

What makes it different

Single binary with zero runtime dependencies, block-level deduplication, and point-in-time recovery support without cloud dependencies.
