As Don says, you're limited to the size of the lowest capacity tape in
the cycle. But if you've got enough tapes to replace the entire cycle
this procedure might work well:
1) Use 'amlabel -f' to give the 20GB tapes the same labels as the old
8GB ones.
2) Switch tapetype in amanda.conf over to a 20GB capacity.
3) Start the next day by backing up to the tape amanda asks for but from
the 20GB instead of 8GB tapes.
4) Keep your 8GB tapes around until the end of the backup cycle. Should
you be asked in the middle of the cycle to restore something you'll need
to have the previous cycle's worth of tapes to feed to amrecover.
5) You should have succesfully slipped a new tape cycle in.
What you want to avoid is using 'amrmtape' on your 8GB tapes because as
soon as you do that you'll no longer be able to restore off of them.
If you don't yet have enough 20GB tapes to replace your entire 8GB cycle
you might want to think about doing the above but without step 2. You
can use just the first 8GB of the 20GB tape without any trouble. Then
if you later on got the money to replace the rest of the 8GB tapes you
could cycle them in and switch over to a 20GB tapetype.
Anyone out there see a problem with this theory?
