Hey People,
i´m searching for many hours a problem and i´m at the end now.
I have a two node Failover Cluster with Availability Groups. The OS is Windows Server 2016 with Sql Server 2016, all System are up to date.
Two Instances are allready configured with AG and everything is fine. SqlServerWriter is still running if i show it in Powershell with "VSSADMIN LIST WRITERS"
Now is the thing i dont unterstand. I´ve created my two Instances on each server and want to use the AG Feature. For This i go to SQL Server Configuration Manager and mark the "Enable AlwaysOn Availability Groups" at this moment the "SQL Server Writer" dissapear and im not able to perform my backups anymore. Reinstall doenst help, at the same point the VSS Writer dissapear all the time.
If i delete the Instance or disable the Services of this Instance it appears again - Verry confused about that
I´m useing for each instance different Service Accounts
I´m think about an missings Securithy Right. But which one ? Any ideas ?
Thank you Guys!
