Shared Folder Permissions When Running Backup-SPFarm

I have setup a farm according to Medium Security Option on Vlad Catrinescu's blog. I setup a backup of this farm using Backup-SPFarm powershell script. If I grant read/write permissions to Everyone on shared folder everything works fine. But if I limit permissions only to SP_Admin account backup fails.

The solution is to grant the following accounts read/write permissions to shared folder:

  • SP_Admin 
  • SP_Services 
  • SQL_Services 

where SP_Admin is the user account which executes the script.
