Intended users

The site describes FSArchiver as a filesystem backup and deployment tool and recommends a live system such as SystemRescue for restoring a root filesystem.Read 8 Oct 2026 · fsarchiver.org

Data integrity

The site describes checksums for archive contents and says that if an archive is corrupt, other files can still be restored while the damaged file is skipped.Read 8 Oct 2026 · fsarchiver.org

Encryption
