说明
fsarchiver saves and restores filesystems to/from archive files. Unlike tar, it preserves filesystem attributes, ACLs, extended attributes, and can restore to different sized partitions. The tool works at the filesystem level, saving used blocks only. It supports ext2/3/4, XFS, Btrfs, NTFS, and other filesystems, with optional compression and encryption.
