The TSM default policy specifies how TSM manages client files. For example, it specifies that TSM retains up to two backup versions of any file that exists on the client (see Installation and Setup Results for details). Two versions may be enough for most clients. However, if some clients need the last ten versions to be kept, you can do either of the following:
![]() | Storing Directly to Tape
Under the default policy, client files are stored directly to disk. You can also define policies for storing client files directly to tape. In a copy group, simply name a tape pool as the destination. Note, however, that if you store directly to tape, the number of available tape drives limits the number of client nodes that can store data at the same time. |
To create a new policy, you can start by copying the policy domain, STANDARD. This operation also copies the associated policy set, management class, and copy groups. You then assign clients to the new domain.
+--------------------------------------------------------------------------------+ | | |copy domain standard newdomain | +--------------------------------------------------------------------------------+
OR
This operation copies the policy domain, and all associated policy sets, management classes, and copy groups. Within the policy domain named NEWDOMAIN and the policy set named STANDARD, you have:
+--------------------------------------------------------------------------------+ |update copygroup newdomain standard standard standard - | | type=backup verexists=10 | +--------------------------------------------------------------------------------+
OR
+--------------------------------------------------------------------------------+ |validate policyset newdomain standard | |activate policyset newdomain standard | +--------------------------------------------------------------------------------+
OR
![]() | The following conditions result in warning messages during
validation:
|
+--------------------------------------------------------------------------------+ |update node mercedes domain=newdomain | +--------------------------------------------------------------------------------+
OR
TSM will now keep up to ten versions of backed up files for client node mercedes because it is assigned to the NEWDOMAIN policy domain.
