Setup: oi build 151_9
Running in Vbox vm as guest on windows 7 64 host
Trying to get my head around the autosnap process and services.
Its pretty confusing to me, since there seems a million or so sources
of info using google. So much that it's a little un-nerving without
enough knowledge before hand to refine searches.
I found something here:
https://github.com/pdxcat/zfs-auto-snapshot/blob/master/README.zfs-auto-snapshot.txt
Its five years old but seems to be saying it is possible to define in
some way, auto snaps for individual zfs fs or groups of them.
Even says there is an example of such a configuration somewhere.
The page has numbered lines so starting a line 33 I see:
These instances use the special "//" fs-name to determine which
filesystems should be included in each snapshot schedule. See the
description for "fs-name" below.
And on to bottom of page appears to indicate one could configure an
individual filesystem (as example) to have only `frequent' snaps
And set the number to keep.
A little further is says:
The :default service instance does not need to be enabled.
I really could not follow how this is supposed to be done, and it is
not really described in detail.
Also, of course, it is 5yr old.
So, is something like the ability to configure auto snapshots for
individual or groups of zfs fs outside the normal service possible on
recent oi-illumos OS?
(I don't mean `possible' in the sense of writing piles of code .. )
If so, where can I get some detailed (recent) documentation about it?
