Case in point. Let's say I run an incremental on Monday for a particular
group, and another on Tuesday, and for some reason I try to clone one of
the save sets from Tuesday, but the cloning operation fails because it
can't read the save set. If I run another incremental it will capture
all the files since Monday. What I really want is to capture all the
files since Sunday. The only thing I can think of would be to run a
level backup, but this would go all the way back to the previous lower
numbered backup which in our case would be the previous full. That seems
like over kill? Would be nice if you could tell NetWorker to choose a
particular incremental for a particular date.
Will this work: `save -s server -b pool -g group -l incr -t mm/dd/yy` if
I run that command from the server, and mm/dd/yy is Sunday's date?
It might, but I'm not sure of all the ramifications. However, you'd run
that from the client, not the server. Also, you'd want to specify the
time down to the second. I think if you just give a date it'll assume
the beginning of the day (00:00:00). Pull the proper one from 'mminfo'.
I wouldn't risk this strategy.
If your bad incremental were the last one run, it's probably easiest to
just delete it from the media database and rerun the incr.
A fine plan, and even if it wasn't the last you could possibly delete
two or three incrementals to take you back to the right point. These
would not be totally lost since you could scanner them back in in an
emergency.
How long do you go with just incrs? I don't go very long because I'm
sure i'll damage or lose a tape someday and I don't want to invalidate a
ton of other tapes when that happens.
I totally agree - I am not happy to depend on more than about a week's
worth. More than that and I would be wanting a new full or to throw in a
level backup. Recovering a whole filesystem from two weeks of
incrementals is a soul-destroying experience.
