Re: [Bacula-users] Swapping tapes mid job with an autochanger

Thanks John, 

I hate when I think of all the details to provide in the email but forget to 
type them out.

Yes, it's a Dell PV-124T changer with a single LTO4 drive (also single 
magazine, which with a 2nd mag, this wouldn't be an issue).

I tried the auto-label during some testing and the I couldn't get to produce 
the same label format that manually labeling produces via "label barcodes".

I assume you have only 1 LTO4 drive otherwise this would not be a
problem. I swap magazines all the time with jobs running on 1 drive
and use label barcodes on the open drive.

No you can not pause the backup and I do not think you can run label
barcodes when bacula is asking for a tape. There is a way to label new
tapes automatically without running label barcodes. I have never used
that however.
