Hello. I've been experimenting with a series scripts that takes ZFS snapshots every minute, eventually destroying the oldest so that only so many remain available for a given window of time.
This may seem a trivial concern with hard drive sizes being what they are these days, but after running a "zpool history" I started thinking that a ZFS create and destroy being performed every minute would add up to a lot over the course of a few years (current estimate is 62MB/year for the naming scheme of my snapshots). >From what I understand, ZFS compresses metadata by default, so this history probbaly won't take up much space in the grand scheme of things. However, I was curious just the same about wether or not there was a way to prune down, or limit the size of, the zpool history. Also, is there any substantial performance penalty to having a huge history? Thanks for any pointers. -- Geoff _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
