I am dealing with the aftermath of a hardware issue that left me
with several clone tapes that were severely underutilized (less than
50 GB used on an LTO-4 cartridge). Sadly, in trying to stage these
small fragments to better utilize the media, I am discovering (yet
again) that I am also staging large portions of other tapes that
were fully utilized and now they are going to be underutilized. I'm
almost to the point of scrapping the entire clone run from last week
and start over (which of course, I don't have the time to do).
Wouldn't it be really nice if NetWorker provided the capability to
stage just the portion of the SSID/CLONEID pair that was on a
particular tape volume to a new tape? I think it would be. Does
anyone else agree?
While the idea would be nice in theory, I think in practice it would
be a nightmare, and open NetWorker administrators (particularly
inexperienced ones) up to making some terrible mistakes.
To put a counter-argument, which may sound blunt or uncaring: IMHO if
you're worrying about media utilisation on individual tapes, your
company isn't providing sufficient budget for you. Obviously we have
to on an overall scale be congisant of the amount of media that we use
within backup, but I often find that wanting (or needing) to get to
that level of granularity comes from budgetary pressure to be miserly.
Cheers,
Preston.
