Question : Problem: BackupExec - Exchange Backup fast by only 1 Storage Group
Dear community
Exchange-Backup with BackupExec 11d to 12.5.
Something was very strange here ....
I've 4 Storage Groups - for us named SG1, SG2, SG3 and SG4.
SG3 has the largest amount of items (summary of all included users) and also
the largest DB (in summary) size.
Let's assume:
SG3 - 10GB, 300'000 items
SG4 - 9GB, 250'000 items
During our backup window, no other jobs will work on the network (traffic, we backup directly trough our network) and no other jobs on the exchange server (online defrag, ...) are active.
However, BackupExec will backup the SG3 (with granular technology) with a speed of 2000MB/min.
All other storage groups will just backuped with a throughput of 600MB/min.
What every I do ... interchange the backup start time of the SG3 and SG4 - the SG3 will backup with
a higher troughput - SG4 with nearly the same sizes - slower troughput.
I'm a little bit frustrated ... why the other jobs are in the relation so slow?
Can't find any disruption.
Anyone an idea whats happen?
- We've change the backup start time => same results
- We've check and compare the amount of objects and the summary of db size of all SG's
=> the largest one was the fastest one ?!
thanks, regards
A.F.
