Hi guys,
This is a new DPM 2010 on a Windows 2008 R2 server, HP Ultrium 1840 SCSI connected. Backups were running fine to these tapes and backup drive with BackupExec.
One backup drive attached (though there was an Ultirum 460 at one point, which I removed), one protection group, file and HyperV data selected. I ran a long term backup to tape, a few HyperV VMs backed up fine then it started on the file data from one of the servers, it got 1.2Tb into this fine and asked for another tape. No problem, this was about 1.5TB onto a single tape so I was happy with that. However the second tape was only in for a few minutes before it looked for another one, only 50-60Gb had gone onto this one! Both tapes were Short Erased before being used.
So I figured it might just be old tapes so stuck in a brand new one and started a new backup. Again a few HyperV images were on but when it got to the same file data it only got to 600Gb before looking for another tape. Stuck another brand new tape in, 300Gb later it is now looking for a third tape!
So before I cancel this job or enter another tape, what troubleshooting can I do here? Is there any way of seeing WHY DPM wants another tape?
Thanks,
Philip
