5.3.2 Backing Up and Restoring Memory
Cisco MGM allows you to backup and restore memory for selected NEs. For example, if you wanted to
save your settings for a particular NE, you can backup the memory for just that NE.
Cisco MGM backs up configuration and provisioning information residing in the flash memory of an
NE.Cisco MGM provides three methods by which to perform the configuration backup operation:
• Manually on demand
• Scheduling (one time only)
• Periodic, automatic scheduling based on a configurable time set by the operator
The operator can specify the number of backup configurations that should be kept at any given time. The
default number is seven.
Note The maximum number of copies that can be saved is fundamentally dictated by the amount of disk space
available.
The oldest configuration that was backed up is replaced by the current backup depending on the
(configured) number of copies the user wishes to retain at any given time. The memory restore function
in Cisco MGM can then be used to rollback to any one of the previous configurations that was saved.
Once the configuration is downloaded, the operator will need to issue CLI commands to activate the new
configuration.
Note This restore operation would be service affecting as the node will be re-booted to reflect the restored
configuration.
Follow the procedures described in these sections to backup and restore memory (configuration data) on
NEs within the following products:
• MGX8880
• MGX8850
