Backing Up Windows Systems
Chapter 5 185
See “Using Backup Options” on page 225 for information on using and
structuring your backup specifications.
Backing Up Windows Shared Disks
Data Protector allows you to back up data on Windows shared disks. You
have to use a regular Disk Agent client, which can then be used to back
up other remote systems via shared disks. Then you can configure a
backup specification.
NOTE Backup using the shared disk method is a workaround for backing up
systems which cannot be backed up otherwise. It is better not to use it as
the main backup approach.
When to Use
Shared Disks
Backup
Use shared disks backup in either of the following situations:
• The remote system does not belong to the Data Protector cell and does
not have the Data Protector Disk Agent installed.
• The platform to be backed up is not directly supported by Data
Protector, for example, Windows 3.11.
TIP To reduce the network load, the Disk Agent client should be the Media
Agent client as well. Otherwise, data is transferred over the network
twice.
You can use one Windows client to manage backups and restores
involving shared disks or other remote systems. Backup performance
may be reduced if you start too many backups at a time, since one Disk
Agent is started for each backed up disk. In this case, you should
configure additional Disk Agent clients to increase the backup speed.
Limitation Backing up writers that store their data on network shared volumes
using the VSS functionality is not supported.
