I'm having trouble trying to do a simple backup of our 2-server SharePoint 2010 farm. I'm running the backup process with a Powershell command, backing up to a UNC shared folder on the SharePoint server.
I have SP2010 on one server and SQL 2012 on another. SQLserver.exe is being run by a new Managed Service Account. I have put this account into a new group and then I gave that group read/write permissions on the backup share at both the Share and Filesystem level.
My farm account also has read/write access to the backup folder. I'm starting my backup process via Administrator account.
My backup commands:
Add-PsSnapin Microsoft.SharePoint.Powershell Backup-SPFarm -Directory \\SHAREPOINT\Backup\Sharepoint -BackupMethod full
The error I'm seeing:
[8/13/2012 12:07:01 PM] Warning: [SharePoint_Config] Cannot open backup device '\\SHAREPOINT\Backup\Sharepoint\spbr0001\000000C6.bak'. Operating system error 5(Access is denied.). BACKUP DATABASE is terminating abnormally.
I'm thinking that for some reason MSAs aren't supported with this backup method but I can't find any information on this anywhere. SharePoint 2010 doesn't support using MSAs for running the services but SQL 2012 does.
I am unable to use the MSA as a login account to be able to check if it can access the UNC from the SQL Server properly like I would a normal account.
