Exchange 2010 Backup : Updating Catalogs Very Long

When backing up Exchange Server 2010 it appears to backup the data with zero issues.  However, it takes 20+ hours to run a Differential backup due to the length of time it takes to update the catalogs.  This was an issue for us in the previous version of Backup Exec 2010 R3.  The issue was not consistent though.  For instance; in 2012 we had an issue in late July and early December.  The issue in July seemed to correct itself?  The issue from December is still ongoing.

The backup rate is at about 282 MB/min.  Whereas while updating catalogs runs at about 1 MB/min.  This definitely appears to be the issue as the entire backup is less than 10GB.  The full backup runs normally and does not take an extended period of time while updating catalogs.

For all Exchange backups we are running GRT.

Any help would be greatly appreciated.

    Any progress on this one ?

    Just got hit.

    Incremental backup of my exchange 2010 server hangs on Updating Catalogs with BE 2012 fully patched.

    I think we'll just have to pray and wait for BE 2010 R2 and BE 2012 SP2....

    ...er, BE 2010 R3 was released a while back which superceded BE 2010 R2...I suspect you mean whatever version will replace BE 2010 R3 SP2!

    Thanks!

    We are having the very same issue.

    actually now we're testing bews2012 as a candidate for production.

    DAG Exchange 2010 (2 db servers, 2 cas servers) all fixes are up to date

    bews2012 all patched up

    agents are also up to date

    backing up to raid-5 de-dublicated disk array on windows server 2008r2 with more that 100MB\sec write speed using 1Gb link.

     

    the full backups are seems to be at normal (at least acceptable) speed, but incrementals are disaster !

    having 1.7TB total size (4 DBs) incrementals are at speed 10-30MB\sec on updating catalogs state.

    Waiting very much for a patch.

    I've got my hands on the new beta SP2 now - after installation and agents updating (reboot was required)

    i'm now testing the full back up of my DAG - exchange 2010 sp2 rollup6

    i've created a new job leaving all by default exept i've unckecked the checkpoint restarts.The job is backuping to de-dup disk device.

    (exchange options - passive then active copy)

    i may say that the speed is just terrible now...

    well, it was about 1500-2700MB\min (i got pure 1Gb low latency network with no network issues) after the beta sp2 it's about 450-550MB\min which is terrible!

    I'm backup up from physical to physical servers...

    Please advice.

    I cant remember, but i think there were some registry related settings for improving performance of  a BEW agent and Exchange back up - i'm afraid they were overwritten by update.

    oh no, i was wrong - it was vmware related  and actually worked very well!! https://www-secure.symantec.com/connect/blogs/performance-tuning-keys-vmware-backups-and-restores

    now i'm trying a full backup to simple disk device - the speed is 3500mb\min stable from the start!

    what the heck?! Where to look for the issue?
