Kirk McKusick implemented snapshots and background-fsck for BSD FFS/UFS
in FreeBSD. AFAIK this is still experimental. (especially

The Linux LVM can do snapshots of volumes. You have to bring the file

not, you get trouble with a unclean file system on the snapshot. If you
use XFS you can do this with xfs_freeze(8).
