A Storage Location should be used by only one media server. When multiple media servers use the same Storage Location, if the Storage Location is deleted from one media server, then the other media server can no longer access it.
Storage Locations must be in a Windows Domain or Active Directory. Computers running the Desktop Agent can be outside of a Windows Domain or Active Directory. However, the computers must authenticate with the domain or directory to access the media server or Storage Locations. Users are prompted to provide domain credentials when the Desktop Agent is launched.
If your original files reside on an NTFS volume, then the desktop user data folder and the network user data folder should also be NTFS. If your original files are on NTFS and either the desktop user data folder or network user data folder are on a FAT or FAT32 volume, you may see duplicate entries in the Restore and Restore Search screens. If duplicates do appear, you can select either file to restore.
After you create a Storage Location, you cannot change it. However, you can delete a Storage Location if no users or Automated User Assignments are assigned to them. You can move users to new Storage Locations.
See Moving Desktop Agent users to a new network user data folder.
If you receive errors when creating Storage Locations, verify that the logon account for the service named MSSQL$BKUPEXECDLO has sufficient rights to create directories and change permissions for the Storage Locations. Use the Windows Service Control Panel to change the logon account for the MSSQL$BKUPEXECDLO instance. You can avoid these problems if you specify a domain account when you install Backup Exec.
