In a project originally funded under Google's 2006 Summer of Code program, Correia has converted the ZFS implementation from OpenSolaris into a server or daemon program that runs on Linux.
Due to the recent surge of interest in porting ZFS to the Linux kernel (if you are in the mood to read dozens of messages, see this thread, the follow-up, plus this one and one more), I'd like to offer my view on things.
ZFS snapshots with 'zfs send' and 'zfs recv' is a better way. Due to its architecture, snaphots in ZFS are very fast and only take up as much space as much data has changed. For a typical user, taking a snapshot every day, for example, will only take up a
