11.1.4 Additional backup options for Windows
In this section we discuss backup options available for Windows clients only:
Adaptive subfile backups should be used if backups are sent on a device with
very limited bandwidth, such as a modem. Only changed portions of the files
are sent over the network. This reduces traffic in the network and speeds up
backup as well. Set the subfilebackup, subfilecachepath, and
subfilecachesize in the client options file, dsm.opt.
You can perform Open File backups on Windows 2000/2003/XP clients if the
Logical Volume Snapshot Agent (LVSA) is installed and configured. Tivoli
Storage Manager takes a point-in-time copy of a file that is locked (opened)
by another application. LVSA can be installed using the client configuration
wizard.
You can back up the Windows 2000/XP system objects together or
individually. We recommend that you back it up together to maintain
consistency. For Windows 2003 clients, you can back up system state and
system services. Tivoli Storage Manager uses the Microsoft Volume
Shadowcopy Services (VSS) to do this. Figure 11-4 on page 345 shows how
to back up the system object from the Tivoli Storage Manager GUI. We
recommend that you perform a full backup of all the components of the
system object at the same time so that it is in a consistent state.
