FSArchiver – disk cloning utility

FSArchiver is a system tool that allows you to save the contents of a filesystem to a compressed archive file.

The filesystem contents can be restored on a device which has a different size and it can be restored on a different filesystem.

Unlike tar/dar, fsarchiver also creates the filesystem when it extracts the data to devices. Everything is checksummed in the archive in order to protect the data. If the archive is corrupt, you just lose the current file, not the whole archive.

FSArchiver can extract an archive to a partition which is smaller that the original one as long as there is enough space to store the data. It can also restore the data on a different file-system, so it can use it when you want to convert your file-system: you can backup an ext3 file-system, and restore it as a reiserfs.

This is free and open source software.

Features include:

  • Support for basic file attributes (permissions, ownership, …).
  • Support for basic file-system attributes (label, uuid, block-size) for all Linux file-systems.
  • Support for multiple file-systems per archive.
  • Support for extended file attributes (they are used by SELinux).
  • Support for all major Linux filesystems (extfs, xfs, btrfs, reiserfs, etc).
  • Support for FAT filesystems (in order to backup/restore EFI System Partitions).
  • Experimental support for cloning ntfs filesystems.
  • Checksumming of everything which is written in the archive (headers, data blocks, whole files).
  • Ability to restore an archive which is corrupt (it will just skip the current file).
  • Multi-threaded lzo, gzip, bzip2, lzma/xz compression: if you have a dual-core / quad-core it will use all the power of your CPU.
  • Lzma/xz compression (slow but very efficient algorithm) to make your archive smaller.
  • Support for splitting large archives into several files with a fixed maximum size
  • Encryption of the archive using a password. Based on blowfish from libgcrypt.
