Avamar and VSS errors

Hello All,

We are experiencing an interesting combination of Avamar errors associated with certain Microsoft Volume Shadow Copy Service (VSS) errors logged in system and application event logs on our Windows 2003 SP2 servers. In Avamar logs we find errors 7831, 6197, 7826, 1 (always the same combo) and in event logs we see Event ID/s: 8019, 12302 in Application log. Interesting part is these errors seem to disappear the next or the following day only to reappear a few days later exactly the same way. Some times it takes up to two weeks for these errors to reappear on the same server. We have already applied Microsoft KB940032 and Patch MS940349-V3. No luck so far…..Any ideas or suggestions?

Thank You!

Re: Avamar and VSS errors

Do you have any 3rd party snapshot providers installed? Like OFM or OTM?

can you give the output from "vssadmin list writers" and "vssadmin list providers" please?

can you make a snapshot from the command line? try running the "vssadmin create shadow" command (server products only)
