You can manage backups, recovery operations and your media with
BRMS by using either the BRMS plug-in to iSeries™ Navigator or through the character-based
interface. If you have used the character-based interface in the past and
want to use the BRMS plug-in, you should be aware of the differences between
these two interfaces.
Terminology differences
The following table describes
the different terminology that exists in each interface and the definitions
of these terms.
Table 1. Terminology differences between the BRMS
plug-in and character-based interfaceBRMS plug-in to iSeries Navigator |
Character-based interface |
Definition |
Backup policy |
Backup control group and media policy |
A backup policy is the combined attributes of a backup
control group and the media policy in the character-based interface. Both
of these functions control how, when, and where a backup is performed. |
Changes-only save |
Non-incremental cumulative backup |
Saves only those items that have changed since the last
full save was performed. |
Media pool |
Media class |
A grouping of media based on similar characteristics,
such as density and capacity. |
Disk pool |
Auxiliary storage pool |
A software-defined group of disk storage units on a
system. |
Disk pool group |
Auxiliary storage pool class |
A group of disk pools that are organized by similar
purpose. |
Container pool |
Container class |
A grouping of similar types of containers that hold
similar media volumes. |
Compatibility differences
If you are currently using
the character-based interface control groups and they do not reference the
system policy (*SYSPCY), archive policy (*ARCPCY), backup policy (*BKUPCY)
and do not share media policies among control groups, then using the BRMS
plug-in should have no functional impacts to your character-based control
groups. If this is not true, read the following information:
The backup
and archive policies created by the BRMS plug-in can be viewed and run from
the character-based interface. Also, control groups created from the character-based
interface can be viewed and edited via the BRMS plug-in backup and archive
policy properties. A message will be presented to the user when a character-based
created or edited control group is about to be changed by the BRMS plug-in;
the user will have the opportunity to cancel the operation or continue. However,
changing control groups created on the character-based interface using the
BRMS plug-in is not recommended unless you understand the following:
- The BRMS plug-in backup and archive policies are designed to be independent
of each other. Thus, if you make changes to one policy, it will not affect
the others. To ensure this independence, control groups updated with the
BRMS plug-in will have all references to the character-based interface system
policy (*SYSPCY), archive policy (*ARCPCY), and backup policy
(*BKUPCY) removed. These references will be resolved and replaced with the
actual values when the backup policy is saved by the BRMS plug-in. The archive
policy, backup policy, or system policy do not affect backup or archive policies
created or edited by the BRMS plug-in. The exceptions to this are the network
function, sign off exceptions, and subsystem to check controls in the system
policy, which are used by the BRMS plug-in.
- The BRMS plug-in hides the media policy from the user (no BRMS plug-in
functions exist to show or edit media policies). Media policy attributes
are indirectly shown and edited through backup and archive policy properties.
As mentioned earlier, the BRMS plug-in backup and archive policies are designed
to be independent of each other. To ensure this, the BRMS plug-in will create
a new media policy based on the currently used one if the control group being
edited contains a media policy that is used by other control groups or is
a shipped BRMS media policy. If a new media policy is created, the control
group will be changed to use the new one.
- When you create a new backup or archive policy using the BRMS plug-in,
it will use a new media policy that is dynamically created.
- Changes made to other, non-IBM supplied policies are reflected in the
BRMS plug-in.
