Hi,
I am posting this here and logging a case for it with Symantec in the hope that someone has a fix...
I am backing up a lot of VM's on VMware using NBD (Soon to be SAN Transport) with a target of a deduplication store located on an EMC VNX SAN attached via fibre.
Most backups are of fairly small VM's with no GRT option selected and these are fine...
I have two file servers which have 800GB and 1.2TB of data stored as VMDK's, for these servers I require GRT so I have enabled only Backup Exec GRT...
The backup for these two servers takes approximately 10 hours total... (2900 and 3200MB a minute throughput according to job log)
Then the catalog process begins and eventually I have to cancel it because it takes such a long time... In 7 hours it had cataloged approximately 200GB of data with a job rate of around 750MB a minute!!! What is really frustrating here is that the server does not appear to be doing anything... IO to the SAN as measured by EMC PowerPath is minimal...
Once I cancelled this the job then began a verify...
Somehow the verify takes 16 hours at 1765 MB a minute (So it is actually taking longer to verify the backed up data than it does to actually back it up?)...
Am I missing something here?
Basically a GRT backup of my file servers at this moment in time is pointless because cataloging the data is so horrendously slow... I saw BE 2012 had similar issues with large amounts of files on AVVI jobs but thought this had been resolved...
More detail:
Dell R710 with 2 x Quad Core Intel E5530 with 16GB of RAM running Backup Exec 2014 with all updates installed on Windows Server 2008 R2 Standard with all updates installed. Microsoft Forefront 2010 AV installed with Excluded files and locations set for the entire C:\Program Files\Symantec folder and the entire drive holding the deduplication store
