In May we renewed our license. Last year we did not buy the advance open file option, but with version 12 it is included. We have one server, our main fileserver, that always gives the following error: "V-79-57344-34110 - AOFO: Initialization failure on: "\\SERVER.DOMAIN.COM\D:". Advanced Open File Option used: Symantec Volume Snapshot Provider (VSP). AOFO: Unable to get minimum quiet time for physical volumes. Reduce the activity on these volumes, or wait and run the backup when there is less activity on the volumes."
Backups are done at night (2AM), there shouldn't be many people using the system at the backup time. As what I found online, I reduced the quiet time and defragged which did not help the issue.
Any help is much appriciated.
