5.9 Recovery Manager
5–16 Management Tools
5.9.3 Partial Configuration
Partial backups and restores provide more flexibility and control over networks than
do backups and restores of entire hubs. Partial configurations include backups and
restores of the following:
• Individual slots or groups of slots
A device failure is an example of when to execute a partial configuration —
in this case, to restore saved parameters to the replacement device. Rather
than restore the entire hub, you can choose to restore only the slot (or group
of slots) from a previously saved backup.
Another example is to restore the configuration of a device to another like
device in a different slot in the same hub; this can be compared to using
Recovery Manager in a dubbing mode.
• Individual parameter subsets or groups of parameter subsets within each slot
Recovery Manager provides more flexibility by allowing you to backup and
restore selected parameter subsets rather than all subsets supported. For
example, if you wanted to copy only the address filters from one DECswitch
900 bridge to another in the same hub, leaving the protocol filters and span-
ning tree parameter subsets intact on the destination bridge, you would select
only the address filters subset in a restore operation from the source backup
file to the destination slot.
