About user-directed backups of SharePoint Server and SharePoint Foundation
User-directed backups of SharePoint Server must be performed from the front-end Web server. Back up the Content, Services, and User profile databases together.
If the policy that has a user backup schedule enables consistency checks, these checks are also performed before user-directed backups.
Note:
If you open multiple backup windows (in the NetBackup client) to browse SharePoint resources, the windows may unexpectedly terminate. Instead, use a single backup window to browse SharePoint resources for backup.
