Installing Network Accelerator Agents
VERITAS Backup Exec and Computer Associates ARCserve network accelerator agents can both be installed remotely by
installing the agent to the system from a remote system on the network.
See the documentation for your backup software for more information about how to install the network accelerator
agents.
Backing Up Persistent Images
Backing up persistent images eliminates the possibility of files changing during the back up job. Persistent images always
contain the data that existed when the persistent image was taken. However, backing up persistent images requires that
you perform several steps and should only be performed by advanced backup administrators. Dell recommends that you
use the available open file agents in VERITAS Backup Exec to back up your open files rather than backing up persistent
images.
NOTE: Do not use Computer Associates ARCserve to back up persistent images.
To back up a persistent image correctly to ensure that you can restore it properly, perform the following steps:
1. Use the NAS Manager to create a persistent image.
NOTE: For increased performance, only back up read-only persistent images.
2. On the NAS Manager primary menu, click Maintenance, and then click Terminal Services.
3. Log on to the system.
4. Using the Windows Explorer, browse to the persistent image you created in step 1.
Persistent images are located in the Dell ActiveArchive™ directory of the volume on which you created the
persistent image in step 1.
5. Right-click the persistent image, and then click Sharing... .
6. Click the radio button adjacent to Share this folder.
7. Enter a name for the share in the Share name text box.
8. Click Permissions.
9. Set the required permissions in the Permissions window, and then click OK.
10. Click OK in the Properties window to finish the share creation process.
11. On the system that is running VERITAS Backup Exec, set up VERITAS Backup Exec so that it is able to back up
user shares.
You can find this option in Tools—> Options menu on the Network tab.
12. In the VERITAS Backup Exec Backup Selections window, browse to your NAS appliance under Entire Network.
13. Select the share name that you created for your persistent image.
14. Deselect the Persistent Storage Manager State directory when performing persistent image backups.
This directory contains files needed for persistent images. However, to save space on your backup media, backing
up the files is not recommended.
15. Click Backup.
16. Select Run Now to run the backup now or Schedule to schedule your backup job to run at a later time.
