HotCopy (R1Soft) Disk and Volume Snapshot Software
High performance disk/volume snapshots for any Linux block device (e.g. hard disk). The copy is writeable but is destroyed on reboot. Good for ensuring consistent backups on busy machines, testing potentially destructive scripts, checking what changes a script or installation makes, etc. Currently free (beta), not clear if it will be payware when it comes out of beta.
