The Backup Settings table lists the cluster settings that are available for backup:

Constructs

Select this check box to select all of the following constructs for backup:

Storage Groups: Select this check box to back up defined storage groups.
Management Classes: Select this check box to back up defined management classes.
Storage Classes: Select this check box to back up defined storage classes.
Data Classes: Select this check box to back up defined data classes.

Partitions

Select this check box to back up defined partitions.

Note: Resident and Object partitions are ignored.

Inhibit Reclaim Schedule

Select this check box to back up the Inhibit Reclaim Schedules that are used to postpone tape Reclamation.

Note: If the cluster does not possess a physical library, the option to Inhibit Reclaim Schedules is not available.

Library Port Access Groups

Select this check box to back up defined library port access groups.

Note: This setting is only available when all clusters in the grid are operating at microcode level 8.20.0.xx or later.

Library port access groups and access group ranges are backed up and restored together.

Categories

Select this check box to back up Categories that are used to group virtual volumes.

Physical Volume Pools

Select this check box to back up physical volume pool definitions.

Note: If the cluster does not possess a physical library, physical volume pools are not available.

Physical Volume Ranges

Select this check box to back up defined physical volume ranges.

Note: If the cluster does not possess a physical library, physical volume ranges are not available.

Security Settings

Select this check box to back up defined security settings, including the following:

Session Timeout: Specifies the number of hours and minutes the management interface can be idle before the current session expires and the user is redirected to the login page.
Account Expiration: Defines whether and when policy accounts can expire. This setting includes the number of days a policy account password can be used before it expires.
Account Lock: Defines whether and when policy accounts can be locked after a number of successive incorrect password attempts. This setting includes the maximum number of successive times a login attempt can fail before a user is locked out.

Roles & Permissions

Select this check box to back up defined custom user roles.

Important: A restore operation following a backup of cluster settings does NOT restore or otherwise modify any user, role, or password settings defined by a security policy.

Encryption Key Server Addresses

Select this check box to back up defined encryption key server addresses, including TS7770 Data at Rest Encryption

Cluster Network Settings

Select this check box to back up the defined cluster network settings.

Feature Licenses

Select this check box to back up the settings for currently activated feature licenses.

Note: You can back up these settings as part of the

ts7700_cluster<cluster
ID>.xmi

file and restore them for later use on the same cluster. However, you cannot restore feature license settings to a cluster different from the cluster that created the ts7700_cluster<cluster ID>.xmi backup file.

See Feature licenses for feature license information available for backup.

Copy Policy Override

Select this check box to back up the settings to override local copy and I/O policies.

SNMP

Select this check box to back up the settings for simple network management protocols (SNMP).

Write Protect Mode Categories

Select this check box to back up the settings for write protect mode categories.

To back up cluster settings, click a check box next to a setting you want to back up and then click Download. A window opens to show that the backup is in progress.

Attention: If you navigate away from this page while the backup is in progress, the backup operation is stopped and the operation must be restarted.

When the backup operation is complete, the backup file

ts7700_cluster<cluster
ID>.xmi

is created. This file is an XML Meta Interchange file. You are prompted to open the backup file or save it to a directory. Save the file.

Important: When prompted to open or save the file to a directory, it is recommended that you save the file without changing the .xmi file extension or the file contents. Any changes to the file contents or extension can cause the restore operation to fail. To retain this backup file, modify the file name before you complete a subsequent backup. If you choose to open the file, it is recommended that you NOT use Microsoft Excel to view or save it. Microsoft Excel changes the encoding of an XML Meta Interchange file, and the changed file is corrupted when used during a restore operation.

The following settings are not available for backup or recovery:

User accounts
Security policies
Grid identification policies
Cluster identification policies
Grid communication encryption (IPSec)
SSL certificates

Record these settings in a safe place and recover them manually.
