Mailing List Archive: what are the columns in `snap list` ?

I've poked around a bit, and I can't figure out what each column in the
output of `snap list` means.

Here's a snippet of snap list on my filer:
%/used %/total date name
---------- ---------- ------------ --------
26% ( 0%) 14% ( 0%) Nov 02 00:00 nightly.5
28% ( 3%) 16% ( 1%) Nov 01 00:00 nightly.6
30% ( 3%) 17% ( 1%) Oct 31 00:00 nightly.7
31% ( 3%) 18% ( 1%) Oct 30 00:00 nightly.8
33% ( 3%) 20% ( 1%) Oct 29 00:00 nightly.9
35% ( 5%) 22% ( 2%) Oct 28 00:00 weekly.1
36% ( 2%) 23% ( 1%) Oct 27 00:00 nightly.10
37% ( 2%) 23% ( 1%) Oct 26 00:00 nightly.11
38% ( 3%) 25% ( 1%) Oct 25 00:00 nightly.12
39% ( 3%) 26% ( 1%) Oct 24 00:00 nightly.13
41% ( 4%) 28% ( 2%) Oct 21 00:00 weekly.2
42% ( 4%) 29% ( 2%) Oct 14 00:00 weekly.3
44% ( 6%) 32% ( 3%) Oct 07 00:00 weekly.4
47% ( 9%) 36% ( 4%) Sep 30 00:00 weekly.5
48% ( 3%) 37% ( 1%) Sep 23 00:00 weekly.6

According to the MRTG graphs, I'm using 88% of my snap reserve at this
point. How can I tell that from the snap list command? What does "%/used"
and "%/total" mean?

I'm sure this is very basic, and I would gladly RTFM, if only I knew where
to look.

Thanks,

I assume you have date and name covered.

%/used is the percentage of space the snapshot takes based on the amount
of data.
%/total is the percentage of space the snapshot takes based on total
disk size.

So let's say hourly.0 is using 100mb, you have 500mb of data, and your
disk is 1000mb.

%/used would be 20% (100mb/500mb) and %/total would be 10%
(100mb/1000mb).

The number on the left not in parentheses is the percentage of that
snapshot and all the snapshots newer than it. The number in parentheses
is the percentage of that snapshot only. So the number in parentheses
could be all over the place. The number not in parentheses will slowly
climb.

You probably can't find it in the manual because it is in the Data
Protection Guide, not the big sucker.
