we are running SME 5.0 on windows 2008 servers. exhcnage 2007. while backup i am receiving following error.
[08:01:14.035] Status for writer Microsoft Exchange Writer: FAILED_AT_PREPARE_SNAPSHOT(0x800423f3 - VSS_E_WRITERERROR_RETRYABLE)
[08:01:14.035] Exchange has reported error writer status. [08:01:14.035] Error code: 0x800423f3 VSS_E_WRITERERROR_RETRYABLE: The writer failed due to an error that might not occur if another snapshot is created.
can anyone tell what could be the reason for this.
Indeed I'm using Windows 2008 (as the original poster stated). There is another backup solution present on the system (Tivoli Storage Manager), however it was inactive during my tests. I am very sure of that.
I know there is an issue of TSM using the ONTAP VSS provider, but I was not aware that this could interfere with my SME backups. Can you elaborate on that, please?
It doesn't seem to be a specific database, because I can backup them individually. Just not as a group. A single log-LUN is shared amongst 10 databases (each on their own LUN), so I should backup these 10 databases at the same time. And I have 4 such groups to backup (= 40 databases). Each database is about 400 GB.
When we've seen this is in our environment, we fail the active node to the passive, reboot the active node (windows clusters) and then fail back. Sometimes the VSS writers fail and only thing to fix it is reboot.. It's windows
