Backup Central

Hello everyone,

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.

Hello everyone,



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

Bacula can not do this because it only recycles volumes when a volume
is needed. Before running a job it does not have any idea how many
volumes would be needed. One way for you to figure out what tapes it
will ask for is to sort your destination pool by lastwritten.

John,

Thanks for the reply. I will give that a try and work on a script that will
tell me the next two tapes I could use based on the last written date.
