Dell PowerVault 725N (Rackmount NAS Appliance) - Manual (Page 141)

If a file becomes inaccessible because of the 255-character limit, perform the following steps to ensure that you can access long path and file names in
Windows Explorer:
1. Create a share for the desired snapshot folder. For example:
E:\ActiveArchives\Snapshot 01-01-2001 12.00.00\
2. Access that share through the desired client.
The path and filename no longer include the additional directory information, which shortens the path and filename to the original character length. You can
now access the file through Windows Explorer.
Restoring Volumes From an Existing Persistent Image
To restore a volume(s) from a persistent image, you must select the persistent image to be restored. Ensure that you select the persistent image carefully
because any activity that occurred after the persistent image was taken is lost.
To restore volumes from a persistent image, perform the following steps:
1. Log in to the NAS Manager.
2. Click Disks.
3. Click ActiveArchive.
4. Click Restore Persistent Images.
5. Click the persistent image that is to be restored.
6. Click Restore.
7. Click OK to restore the volumes protected by the persistent image, or click Cancel to leave the volume intact.
Changing the Dell ActiveArchive Event Log Language
Applying a selected language changes the graphical user interface to that language, but it does not change the language in which the Dell ActiveArchive event
log messages are generated. The messages are generated in English unless you run a batch file to change the language to one of the following supported
languages:
l English
l French
l German
l Japanese
l Spanish
To change the language in which the event log messages are generated, perform the following steps:
1. Log in to the NAS Manager.
2. Click Maintenance.
3. Click Terminal Services.
NOTICE: Restoring a volume restores the volume back to its state at the time the persistent image was made. This restore destroys all data on the
volume and replaces it with the data from the persistent image.
NOTICE: A volume is dismounted during a restore. All reads and writes to a volume that occur during the restore process are denied. Therefore, you
must stop all I/O traffic to a volume while restoring it.
NOTE: Restoring persistent images that contain multiple volumes restores all of the volumes in the persistent image. If you want the ability to restore a
single volume, you must take single volume persistent images.
NOTICE: If you delete a share from a volume after a snapshot is taken, that share will not be accessible after you restore the snapshot. For example, if
you create a persistent image of volume E, which has a share called "users," and you later delete "users," when you restore volume E, the "users"
share will not be accessible, although the directory will still exist and contain the files.
