Backing up Ex2010 problem
We are having a problem to backup one information store. Both in full backup and incremental backup it fails at some point with following error:
V-79-57344-915 - Unable to complete the operation for the selected resource using the specified options. The following error was returned when opening the Exchange Database file: '-1022 There is a disk IO error. '
We are backing up to a dedupe folder. AOFO is off and GRT is on.
Any suggestions what could be the cause?
