Sharepoint “can” be backed up by the SBS server manager backup, which is the built in windows backup for itself provided out of the box. This is not favorable as most customers and most of our networks need more granular management, so we use Backup Exec. That said, backupexec’s backup of sharepoint can’t always be trusted. Therefore, we do 2 things to ensure we can restore sharepoint.
1. We do let BackupExec attempt to back it up.
2. We create a batch file that does a detailed backup of sharepoint and dumps it to a folder. BackupExec can then pick up that folder on its backup routine as well. This backup script below is from MSFT and works well. Just save it as a batch file and automate it as a scheduled task
