Managing NE backups and restores
A 5620 SAM backup policy specifies the conditions under which the 5620 SAM
performs an NE configuration backup to ensure that the device configuration is not
lost in the event of a failure. A default policy that is assigned to all managed NEs is
in place after a 5620 SAM installation. You can create and configure multiple
backup policies, and you can assign them to multiple NEs. You must unassign all
NEs from a backup policy before you can delete the policy. The information in a
backup policy includes the following:
• the frequency of backups
• the files that a backup collects
• the type of file compression that the 5620 SAM uses
• the age and number of backup files that the 5620 SAM retains
You can perform an on-demand export of backup files from the 5620 SAM to a client
file system, and can import NE backups from a file system to the 5620 SAM. The NE
backup files are synchronized between the primary and standby main servers in a
redundant 5620 SAM deployment.
You can configure the 5620 SAM to automatically delete device backup files after
the associated NE is unmanaged. See chapter 6 for more information.
When a device configuration requires replacement, for example, because it becomes
corrupted, you can restore a previously backed-up configuration. Unless otherwise
specified, the 5620 SAM restores the most recent device configuration backup. See
Procedures 8-4 and 8-7 for more information.
As a restore policy works implicitly with a backup, there is no explicit restore policy.
The user must select the imported or pre-existing backup file and click Restore.
Managing NE software upgrades
You can use the 5620 SAM to perform scheduled or on-demand NE software
upgrades, including ISSUs. A software upgrade requires a software upgrade policy.
A software upgrade policy contains settings such as the device family, file transfer
credentials, software image and backup locations, and the actions to perform; for
example, image download, activation, or ISSU. Depending on the device family, the
activation function supports the reboot and reboot upgrade options. See “Reboot and
reboot upgrade” in this section for more information.
Using a software upgrade policy, a 5620 SAM operator can independently perform
the image download and software activation tasks. For example, you can configure
a policy to perform the time-consuming software image downloads only, and then
schedule the image activation as a separate task. When the image downloads are
performed in advance, the 5620 SAM can perform more activations in one
maintenance period.
