Is there a way to *manually* rollover snapshots retaining the .number sequence? That is, without doing this in a script:

rsh filer snap delete vol0 nightly.N rsh filer snap rename vol0 nightly.N-1 nightly.N ... rsh filer snap rename vol0 nightly.0 nightly.1 rsh filer snap create vol0 nightly.0

Reason is, I need to do a few things just before midnight and then a few things after midnight, but the things before midnight might not finish exactly before midnight when the filer makes the nightly snapshot, and I need them to be included in the read-only snapshot.

So, I'd like to do something like:

1. do my pre-midnight commands 2. rsh filer snap nightly 3. do my post-midnight commands

("commands" are things done from an NFS mount to manipulate the data/files on the filer, not commands executed on the filer itself)

and have step 2 do all the numbering bookkeeping for me, according to the snap schedule.

Probably not, since that would mean some other switch to tell the filer *not* to the automagic snapshots. But, I'd thought I'd ask anyway, in case anyone has any better ideas.

Orrrrr, how about a resnap? I could let the filer make its nightly.0 snapshot as usual, and then a few minutes after midnight, execute something like:

rsh filer snap redo vol0 nightly.0

Oooo, I like that better. That helps with other snapshot manipulations we use, instead of:

rsh filer snap create new rsh filer snap rename image old rsh filer snap rename new image rsh filer snap delete old

Would this be useful enough to more than just me for an RFE?

Until next time...
