I have two Vcenters that I integrated in my master and I have two media or backup host which synchronize with these two Vcenters to distribute the costs of backup operations.
I have a problem, whatever the media used for the write operations of the backups on the DataDomain, the backup speed is fast on one Vcenter and on the other hand on the other Vcenter the speed is very slow and sometimes causes failures backup after a start of writing.
My Netbackup environment is as follows:
- NetBackup version: 8.0
- Master is custom built host (OS version: Red Hat Enterprise Linux Server release 6.4 (Santiago))
- backup host version: Netbackup Media 8.0
- ESXi version: 6.0.
Please what can be the cause of this slow backup operations on this second Vcenter?
