We are using Bacula 5.0.1 running on an Ubuntu 10.04 server attached to a Dell PowerVault TL2000 tape library. I run differential daily backups Monday thru Thursday and a full weekly backup on Friday. I have pools setup for both the daily and weekly tapes and use the list nextvol command from bconsole to determine the next tape I should be using. This works fine for the daily differential backups because they only use one tape each day. However, the weekly full backup always takes two tapes. If I use the list nextvol command for the full backup it only gives me the next single tape to use.
Since I place the tapes in the tape library’s magazine before I leave each day I would like to be able to know which two tapes to use for the weekly full backup. What I have been doing so far is to place in the library all the remaining tapes in the full backup pool. I would prefer for Bacula to tell me what the next two tapes should be used instead. Does anyone know how to accomplish this?
Thanks in advance.
