Configuring the deletion of archived files on placeholder deletion

To configure the deletion of archived files on placeholder deletion, follow the procedure that is appropriate for the type of file server.

Note that Enterprise Vault does not delete archived files in the following circumstances:

For NTFS volumes on which pass-through recall is enabled. This combination of settings can result in data loss.
If the archiving policy applies a retention category with "Prevent deletion of archived items in this category" set. The retention category setting takes precedence.

Note:

Do not configure this option for EMC Celerra devices if you configure the Celerra's pass-through setting. The combination of these options can result in data loss.

To configure deletion of archived files on placeholder deletion for NTFS and NetApp file servers

Select the Delete archived file option on the Delete Placeholder tab of the file server's properties.
We recommend that you specify a safety folder when you use the Delete archived file option. An archived item is not deleted if its placeholder is deleted from a safety folder. On the Delete Placeholder tab, specify the folders to use as safety folders.

A safety folder is useful when a user deletes a file accidentally. You can restore files temporarily from backups to the safety folder so that the user can find the file. The user can delete placeholders from the safety folder without deleting the corresponding archived items.
Where required in your file archiving policies, check Delete archived file when placeholder is deleted on the Shortcuts tab.

Note:

Enterprise Vault does not act on the changes to this setting until it updates the DOD cache.

See How the 'Delete archived file when placeholder is deleted' feature works.

To configure deletion of archived files on placeholder deletion for EMC Celerra file servers

Configure a target volume under the target Celerra file server whose share points to the root of the file system.
Apply an archiving policy to the root volume in which the setting Delete archived file when placeholder is deleted is selected on the Shortcuts tab.
Note that this root volume policy setting controls the deletion of archived files on placeholder deletion for all of the Celerra file system:
- If you configure any additional target volumes that point to specific folders in the same Celerra file system, Enterprise Vault ignores the policy setting that applies to the folder volume.
- Enterprise Vault ignores the "Delete archived file when placeholder is deleted" policy setting in any folder policies that apply to target folders.
Enable FileMover logging on the Celerra device. Logging must be enabled for file deletion to work. You can test whether logging is enabled from the EMC Celerra tab in the properties of the Celerra target volume.
Set the DeleteOnDelete registry value on the Enterprise Vault server whose File System Archiving task processes the root volume.
Set the value as follows:
- Start the Windows registry editor regedit on the Enterprise Vault server.
- Find the following registry key:
```
HKEY_LOCAL_MACHINE
 \Software
  \KVS
   \Enterprise Vault
	\FSA
	 \ArchivedFilesFlags
```
  You must create the ArchivedFilesFlags key if it does not exist.
- Create a registry value named DeleteOnDelete under the ArchivedFilesFlags key, if this registry value does not already exist.
- Give DeleteOnDelete a DWORD value of 1. This value means "Delete an archived Celerra file when its placeholder is deleted".
  
  Alternatively you can turn off Celerra archived file deletion on placeholder deletion by setting this value to 0.
- Save the changes and quit the registry editor.
Restart the Enterprise Vault Admin service on the Enterprise Vault server, to activate the registry change.
Configure the daily deletion schedule for the archived files whose placeholders were deleted.
