What FSArchiver is

FSArchiver is free Linux software that saves filesystem contents in compressed archives and restores them to differently sized partitions or other filesystems. It works at the file level, preserving standard attributes such as permissions, timestamps, links, and extended attributes when kernel support allows. Archives can contain multiple filesystems, and large archives can be split into files with a fixed maximum size. The supported list includes major Linux filesystems and FAT formats, including FAT for EFI System Partition backup and restore; NTFS support is experimental. Compression options include multithreaded LZO, gzip, bzip2, and LZMA/XZ. Archives can be password-encrypted with Blowfish through libgcrypt, and checksums help identify damaged contents. If an archive is corrupt, other files may still be restored while the damaged file is skipped. For a filesystem in use, the project recommends an LVM snapshot because changes on a read-write mounted volume can cause backup problems. Installation options include distribution packages, a static binary, or compiling from source; FSArchiver is also included in SystemRescue. The project identifies version 0.8.x as its latest stable series.

Good

  • Archives can contain multiple filesystems.
  • Preserves standard file attributes when supported.
  • Offers password encryption and checksums.
  • Available through packages, a static binary, or source.

Watch out

  • NTFS support is experimental.
  • Btrfs snapshots are not preserved.
  • Read-write mounted volumes can cause backup problems.

Who it suits

FSArchiver suits Linux users who need file-level filesystem backup and restore, including transfers to differently sized partitions or other filesystems. The project recommends using a live system such as SystemRescue when restoring a root filesystem.

Verdict

FSArchiver covers a broad set of Linux and FAT filesystems and offers compression, encryption, and recovery of undamaged files from a corrupt archive. Consider its experimental NTFS support and filesystem-specific limits before relying on it for a particular restore.
