Is anyyone out there that has used the Terastation with Backup Exec and might be able to help? Im in a serious time crunch and have hit an absolute wall.

Thanks in advance!!!!!!

Checked the share permissions are not set to Read Only as they are by default on newly created Windows CIFS (Not the NTFS folder permissions, Im talking about the actual SHARE access permissions on the CIFS you have created) ?


I have verified that the account I am logging in under is added to the share permissions on XFS share permissions. I have looked to see if I should be using a DIFS file system but the TeraStation does not allow me to format as CIFS on XFS.

Just something I ran up the tree when I saw your post.

This seems to be an issue with the way Backup Exec queries the folders on back up to disk folders. It cannot see the mapped drives from the terastation. Windows mapped drives are no probelm though.

Can you map a drive to it when logged in as the Backup Exec service account? If it's running as local system then you may just need to change it to run under another user.

Thank you for your responses. Unfortunately, I have tried them all and are still in the same boat. I can map windows shares no problem, I can do it with the backup service account login, but as soon as I try to create a backup to disk folder in BE, the access denied error pops up. I have tried UNC PAths and IP Address to map the drive. I have tried both way in BE also. If I attempt to use a mapped drive in any instance, I cannot see the mapped drive in BE to select it. Just use the drive letter anyway? Yep you guessed it, resource not found.

Still huntin' for a solution. Any help is appreciated greatly.

Not much help from Symantec, http://support.veritas.com/docs/237737 . There are people on the Web saying they got it to work as B2D although setting the maximum size of B2D folders to 1GB has been necessary for some. It may need ADMIN$ and C$ hidden shares creating like it does to be able to backup generic NAS boxes.

Hi, there

on that remote backup folder is that windows 2003 SP2 ?. I found when you are using the backup to folder it needs to be mx 2 gb files.

regarding my question on Win 2003 SP2 is caused in Active directory

Local domain security

look here under assign user rights assignment then now on the right hand site there is 4  security settings that needs a "backupexec" account + Domain Administrators, Administrator, Enterprise admins, Backup Operators.

Log on locally
Log on as a service
Backup Files and folders
Restore files and folders

If you under windows explorer can map a drive to your backup folder using credentials as administrator + password on the local box then can you use that as credential in BE.

As a last thing what build of Be is this here 6235 or the 7170. Your license will fit both.


I am running build 6235. I can map the drive no problem using my admin account in active directory. So the AD integration is working. However, BE gives me an access denied even when I use that account for the logon account.
