Crunchy BackRest aims to be a simple backup and restore system that can seamlessly scale up to the largest databases and workloads.
Primary Crunchy BackRest features:
- Local or remote backup
- Multi-threaded backup/restore for performance
- Safe backups (checks that logs required for consistency are present before backup completes)
- Full, differential, and incremental backups
- Backup rotation (and minimum retention rules with optional separate retention for archive)
- In-stream compression/decompression
- Archiving and retrieval of logs for replicas/restores built in
- Async archiving for very busy systems (including space limits)
- Backup directories are consistent PostgreSQL clusters (when hardlinks are on and compression is off)
- Tablespace support
- Restore delta option
- Restore using timestamp/size or checksum
- Restore remapping base/tablespaces
- Support for PostgreSQL >= 8.3
Instead of relying on traditional backup tools like tar and rsync, Crunchy BackRest implements all backup features internally and uses a custom protocol for communicating with remote systems. Removing reliance on tar and rsync allows for better solutions to database-specific backup issues. The custom remote protocol limits the types of connections that are required to perform a backup which increases security.
