I’m aware of ZFS rollback of an entire system … but I vaguely recall reading somewhere that ZFS commands can also be more discrete – rollback or restore of directories or individual files.
John Clingan describes rollback of zones on a ZFS system but zones in this context are limited to Solaris; I’m more interested in ZFS on Mac. Also, zoning does not match the level of discretion (individual files) that I’m seeking.
Am I mistaken in my recollection of
ZFS commands for directory-level or
A March 2007 dicussion File level snapshots in ZFS? suggests CVS or other version control methods. My own thoughts are in line with those of Manoj Joseph within that discussion, but I can’t find a reply to his comments.
Advice/clarification will gratefully appreciated.
My current foci are ZFS for MacFusion and for Linux — keywords for both: FUSE. I’m aware of ZFS for FUSE on Linux and I’m extremely keen on the idea of ZFS for the MacFusion Project with which I’m involved.A May 2006 article ZFS on YOUR Desktop (as noted there, Apple Time Machine is reminiscent) presents an appealing picture.Until recently I have often referred to ZFS: the last word in file systems (2005) but I now find more recent information presenting things in greater clarity:
- St. Petersburg at OpenSolaris.org | How ZFS Works (11 April 2007)
- ZFS FAQ at OpenSolaris.org
- ZFS Source Tour at OpenSolaris.org.
ZFS boot support
Backup, snapshot, rollback and restore aside:
it’s great to read about boot support!
