EMC Avamar 7.0 Release Notes 47
Microsoft SharePoint VSS plug-in
The following table lists known problems for this release of the Avamar Plug-in for
SharePoint VSS.
N/A Public Folders permissions requirements
To back up public folders, set the Exchange Permission Level on the public folders for
the account that is performing the backup to a minimum of Reviewer. In other words,
set the Read permission to Full Details and the Other permissions to Folder Visible on
the Permissions tab of the Mailbox Properties dialog box.
To restore public folders, the account that is performing the restore must have
sufficient permissions to write to the folders and their parent folders. In other words,
the Write permission must have Create Items and Create Subfolders selected, and the
Other permissions must be set to Folder Visible. If the account that is performing the
restore does not have write permissions, then the recover operation is reported as
successful, but no data is restored.
Note: You can set permissions to hide public folders by clearing the Folder Visible
option in the Other permissions on the Permissions tab of the Mailbox Properties
dialog box. If a folder is hidden from the account that is performing the backup, then
the folder is hidden from the backup process. The hidden folder is not saved, and no
errors or warnings are provided.
N/A Upgrade of the Exchange VSS Plug-in with UAC enabled does not offer Exchange GLR
plug-in option
When upgrading the Exchange VSS Plug-in from release 5.x to release 6.0 or later, with
User Account Control (UAC) enabled, you cannot select the Exchange GLR plug-in if you
use the Windows Control Panel > Add/Remove Programs feature for the upgrade. To
enable GLR, disable UAC and use the Add/Remove Programs feature, or run the Avamar
Exchange VSS MSI file from an Administrator command prompt.

N/A Issues after upgrade to Windows SharePoint Services 3.0 SP2
When you upgrade from Windows SharePoint Services 3.0 or 3.0 SP1 to 3.0 SP2 on a
system with the Avamar Plug-in for SharePoint VSS, the SharePoint topology does not
display correctly in Avamar Administrator. This may prevent you from backing up a
SharePoint farm.
