Backup2Disc backup of Exchange hangs on loading media
I have three B2D device configured solely for Exchange Database backups
B2D-1: 1.8 TB
B2D-2: 1.8 TB
B2D-3: 900 GB
My Exchange 2007 backups run successfull now (see: https://www-secure.symantec.com/connect/forums/exchange-backups-keep-failing-vss-writers) but today I noticed that Backup Exec decided to use, out of the Exchange B2D pool (all three above disks), a disk with only 60 GB free and no recycle media. (the backup is about 170 GB)
The other disks have plenty of free disk space ( > 1 TB)
The first 60 GB of the backup went fine until it filled up the disk. Now Backup Exec is waiting with the status message "Loading Media"
Question: Why is Backup Exec not using the disk from the disk pool with the most free space and why is it not continuing on a empty disk? What do I need to do to prevent this from happening?
