New EX2007 SP2 server on new WS2008 SP2 server, all fully patched.
BEWS 12.5 SP2 media server and RAWS, all fully patched. B2D backups.
Exchange is configured with LCR. Per Microsoft, recommended backup for LCR systems is weekly full, daily incremental, so that's what I've been trying to do.
Full Exchange backups with GRT work flawlessly.
Incremental Exchange backups with GRT fail about 90% of the time. All failures relate to GRT. Backups fail on different databases each time (there are 6). Usually, all databases that fail within a given backup job do so with the same error. The errors are as follows, with a rough estimated percentage of jobs it occurs with:
- V-79-57344-759 - Unable to complete the operation for the selected resource using the specified options for the following reason: VFF Open Failure. This can be caused by low memory or disk resources. (90%)
- V-79-57344-759 - Unable to complete the operation for the selected resource using the specified options. The following error was returned when opening the Exchange Database file: '-1213 The database page size does not match the engine. '(5%)
- V-79-57344-759 - Unable to complete the operation for the selected resource using the specified options. The following error was returned when opening the Exchange Database file: '-515 The timestamp in the next log does not match the expected timestamp. '(3%)
- V-79-57344-759 - Unable to complete the operation for the selected resource using the specified options. The following error was returned when opening the Exchange Database file: '-1090 This instance cannot be used because it encountered a fatal error. '(1%)
- V-79-57344-759 - Unable to complete the operation for the selected resource using the specified options. The following error was returned when opening the Exchange Database file: '-501 The log file is corrupt. '(1%)
Remedies in the corresponding KB articles have not solved the problem. Maintenance windows on the databases do not overlap with each other, or with the backup window.
Is anyone successfully doing incremental GRT backups with EX2007? Honestly, I'd just as soon use full backups...incremental Exchange backups make me a little uneasy, MS recommendation or no. So that's probably what I'll do.
But I guess if there's a magic bullet fix for this that doesn't burn a lot of time, I'd like to hear about it.
