%description
This is a Swiss army knife for backup and disaster recovery with deduplicated
snapshots. It efficiently keeps backups, without a need to ever prune. Handles
millions of files and terabytes of data. Non-Latin support. Backups with full
encryption. Data integrity check with CRC32 and XXHASH or SHA-1, SHA-2, SHA-3,
MD5, XXH3, or BLAKE3. Multithread support. Specific ZFS handling functions.
