Multiple tape sizes
Presently, I inherited a VXA-1 rakpak and an assortment of tapes. I have V6, V10, and V17 tapes. Besides under using the v10 and v17, is there any other way to fit different tape capacities into amanda scheduling? Thanks, Adam Read LocalNet Corp.
Re: Multiple tape sizes
Depending on how many of each you have, you could make a separate config for each. Or possibly just use them for archives. I think it would be impossible for planner to level out daily runs if you didn't know what size tapes were going to appear. One other option would be to change to your longest tapelength and increase runtapes, letting Amanda hit EOM on the shorter tapes and just starting again on the next tape. If your DLEs are large then this could waste a fair amount of tape and time. Frank --On Monday, October 21, 2002 13:55:53 -0400 Adam D.

Using Multiple Tape Sizes
We currently use 20 8 gig tapes for our backup in amanda. We have obtained some 20 gig tapes and we would like to add these to the backup schedule. Do we need to replace the 8 gig tapes with the 20's or can we intermix them? Thanks, Brook
Re: Using Multiple Tape Sizes
I would be willing to bet that you could use..them but since the config specifies the tape size, you would only be using the limits of the previous size. I would say add the tapes in your rotation and adjust your tape size to reflect the new tapes. And remove the the 8GB tapes from your rotation.

Set record=no and you could set a real short dumpcycle so Amanda would try and fit as many full backups as possible on the new tapes. The reason for the record=no is to not mess anything up on the existing backup configuration. -- [EMAIL PROTECTED] - HMC UNIX Systems Manager

I think there is only one place to specify a tape size. What size would you specify? Maybe if you specify the 20GB size, and runtapes 1, failed writes would go to the next, hopefully larger, tape. -- Jon H.

I would say add the tapes in your rotation and adjust your tape size to reflect the new tapes. And remove the the 8GB tapes from your rotation. 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? -- Brandon D.
