Hi Omar,
Even though you don't have the AOFO option and have not selected it during the backup job, the job will use the Snapshot technology to backup the shadow copy components of Windows 2003. Hence, the AOFO notes in the job log.
You do not require the AOFO option, however you do need to check if Volume Shadow Copy service start type is set to Manual or is started. Please check the services applet for Volume ShadowCopy Service.
Also, would like to suggest you to check the Event logs for VSS errors.
Thanks, hope this helps you.
If you require further assistance, do reply to this post within two business days else we will assume that the issue is resolved and will archive the post.
