There's a heated debate going on within our backup admins around application aware processing on all Windows VMs, not just those with the relevant applications (AD/SQL/Sharepoint/Exchange etc)
The thinking behind this is that it provides as a 'cleaner' backup of Windows VMs, as it uses VSS to tell the VM to quiesce the OS ("prepare to be backed up"). Unfortunately this leads to added complications as backups are set to "require success" and subsequently failing. Now the obvious work around is to set the "Try Application aware, but Ignore failures" but these jobs complete with a 'Warning' status, as opposed to a 'Failed', which leads to the counter argument "helpdesk don't care about warnings, they only care about failures"
My argument is I'd rather have some kind of backup, over no backup at all.
Interested to hear peoples thoughts on this subject ...or if Veeam would consider adding a 4th option to the application aware "Try application aware, if it fails still take the crash consistent, but report as an error"
