zpaqfranz

Deduplicating, encrypted archiver for disaster-recovery backups with paranoid-level verification.

Desktopfree

zpaqfranz is a deduplicating, encrypted archiver for backup and disaster recovery, forked from the ZPAQ format, that stores repeated backups as space-efficient versioned snapshots rather than near-full copies. It runs on Windows, Linux, and Unix and supports multiple verification hash algorithms up to a paranoid level, aimed at sysadmins who need reliable, space-efficient backup and restore.
