Subject: OK to take hourly snapshots, then cull older ones?
Date: Mon, 14 Oct 2013 21:05:33 -0700 [thread overview]
Message-ID: <525CBF0D.1020609@mersenne.com> (raw)

I'd like to use BTRFS to do something like the old NetApp snapshot
system: every hour or so, there'd be a snapshot, then the 23 of the
snapshots during a day would be deleted, leaving just a day snapshot,
then after a month, 6 of 7 snapshots would be deleted, leaving just a
week snapshot, and so on.
Is this a reasonable thing to do in a cron job with a BTRFS filesystem?
Apart from running out of space, are there any resources that might get
used up? Has anybody done this for a year or two in an active
filesystem, and encountered success or weirdness?
Thanks!
