ntbackup halts Backup Exec job

Created: 27 May 2013 | 4 comments

I am running Backup Exec 2010 sbs edition on Windows server 2003 sbs.

Basically what is happening is if my Backup Exec job runs a little long it bumps into my exchange backup which is scheduled using ntbackup. When this happens it halts BE and throws a system error. The BE exec is backing up to HP RDX drive and the ntbackup is going to a seperate NAS device(large external HD). To prove this problem I had a BE manually doing a failed backup from last night, and as soon as I opened ntbackup utility it halted BE. The errors being thrown suggest a problem with RDX drives, but I have confirmed they are stable. I use 6 different disks and the problem is not specific to any particular one. The only trigger is starting ntbackup, and it doesn't even use the RDX disks for a destination... I also don't see any issues with memory.

Just for completness I will include logs.

Anyone had a similar issue and possibly have any solutions?

I guess you can't use two VSS compliant backup tools at the same time. I once had the very same problem in a customer who had the same idea.

Do not use two backup tools at the same time, specially if using complex backup operations like snapshots based on VSS Provider and not just filesystem copy.

VSS: Volume Shadow Copy Service. https://en.wikipedia.org/wiki/Shadow_Copy

hope it helps.

1) You should turn off RSM as it is not recommended for BE.

2) Are you aware that the BE SBS edition includes a licence to backup Exchange?  You should use BE to backup Exchange, rather than NTBackup.  It is always better to stick to one backup software.

In reality we don't support RSM (at least on the media serevr) any longer and it should be disabled

This of course then scuppers any ability to use NTBackup which I believe requires it.

Thank you for the answers! I have recently stepped into this role, and was just working what was previously in place. I will definately look into your suggestions.
