zfs discuss - Jan 2008 - Updated ZFS Automatic Snapshot Service - version 0.10.

Hi all,

I''ve got a slightly updated version of the ZFS Automatic Snapshot SMF
Service on my blog.

This version contains a few bugfixes (many thanks to Reid Spencer and
Breandan Dezendorf!) as well as a small new feature - by default we now
avoid taking snapshots for any datasets that are on a pool that''s
currently being scrubbed or resilvered to avoid running into 6343667.

Is this service something that we''d like to put into OpenSolaris or are
there plans for something similar that achieves the same goal (and
perhaps integrates more neatly with the rest of ZFS) ?

Otherwise, should I start filling in an ARC one-pager template or is
this sort of utility something that''s better left to sysadmins to
implement themselves, rather than baking it into the OS ?

	cheers,
			tim

Heck yes, at least Indiana needs something like that.  I guess nobody is
spearheading the "Indiana data backup solution" right now, but that
work of yours could be part of it.

To the user there is no difference between "regularly scheduled
snapshots" and "snapshots before software updates".  They are all
just data backups and must be integrated consistently into the same GUI. 
It''ll say "here is the time before last tuesdays update" and
"here is monday morning".  So what you are doing is a piece of that
puzzle.

I guess the IPS guys are working on another piece of the puzzle, meanwhile
nobody is working on the GUI, and nobody is spearheading the whole effort.
