Backing Up and Restoring LAN Operational Mode Setups, Release 12.2.2

The following table provides an overview of the significant changes up to this current release. The table does not provide an exhaustive list of all changes or of the new features up to this release.

The following sections describe how to back up and restore LAN fabrics.

Backing Up a LAN Fabric

You can back up all fabric configurations and intents automatically or manually. You can save configurations in Cisco NDFC, which are the intents. The intent may or may not be pushed out to the switches.

The backup has the information related to intent and fabric configurations in addition to the associated state of the resource manager in terms of used resources on the fabrics. Cisco NDFC backs up only when there is a configuration push.

The following sections describe the necessary steps to back up a fabric:

• Setting the Maximum Number of Backups Per Fabric

• Enabling an Automatic (Scheduled) Fabric Backup

• Enabling a Manual Fabric Backup

• Marking a Backup as Golden

Setting the Maximum Number of Backups Per Fabric

To set the maximum number of backups per fabric, navigate to:

Admin > System Admin > System Settings > Server Settings > LAN-Fabric

Locate the Maximum Backups per Fabric field and enter the number of backups that you want to have stored per fabric. The default entry in this field is 2.

When new backups take place, the oldest (non-golden) backup gets removed automatically. Increase the value in this field only after guidance from Cisco TAC.

---

The backup count also includes golden backups. Cisco NDFC supports a maximum of two golden backups per fabric. See Marking a Backup as Golden for more information.

---

Enabling an Automatic (Scheduled) Fabric Backup

Cisco NDFC triggers an automatic backup only if you did not trigger any manual backup after the last configuration push.

To enable an automatic (scheduled) backup for fabric configurations and intents:

1. Navigate to the Fabrics window:

   Manage > Fabrics

2. Select a fabric from the list of configured fabrics, then click Actions > Edit Fabric.

3. Click the Configuration Backup tab, then enter the necessary information in the fields in this tab.

   Fields	Descriptions
   Hourly Fabric Backup	Check this box to enable an hourly backup only if there is a configuration deployment since the last backup.
   Scheduled Fabric Backup	Check this box to schedule an automatic backup at a specified time, entered in the Scheduled Time field.
   Scheduled Backup	This field becomes editable if Scheduled Fabric Backup is enabled. Enter the time that you want the automatic backup to occur, in a 24 hour (UTC) format (00:00 to 23:59).

4. Click Save when you have completed the configurations in this tab.

Enabling a Manual Fabric Backup

To enable a manual backup for fabric configurations and intents:

1. Navigate to the Fabrics window:

   Manage > Fabrics

2. Double-click on a configured fabric to bring up the Overview window for that fabric.

3. Click Actions > More > Backup Fabric.

4. Enter a name (tag) for the manual fabric backup, then click Create Backup.

Marking a Backup as Golden

Once you have a fabric backup configured (either a manual or an automatic backup), you can mark that fabric backup as golden, indicating that you don’t want to delete that backup even after you reach the archiving limit. Golden backups will not be removed automatically to make space for new backups.

Note the following guidelines with golden backups:

• NDFC archives only up to ten golden backups.

• You can’t delete golden backups of fabrics. However, you can remove the golden backup designation on a particular backup as described below, which would then allow you to delete that backup, if necessary.

You can mark a backup as a golden backup while restoring the fabric. To mark a specific backup as golden:

1. Navigate to the Fabrics window:

   Manage > Fabrics

2. Double-click on a configured fabric to bring up the Overview window for that fabric.

3. Click Actions > More > Restore Fabric.

4. Select the backup that you want to mark as golden, then click Actions > Mark as golden.

   If you want to remove a golden mark on a particular backup, select that backup in this window and click Actions > Remove as golden.

Beginning with NDFC release 12.2.2, a unified backup and restore is now available at the Nexus Dashboard (ND) level, where a backup and restore performed at the ND level backs up not only the configuration information for ND, but also for any services (such as NDI, NDO, or NDFC) running in that ND. With this unified backup and restore feature, the backup and restore functionality at the upper NDFC level is no longer provided through the NDFC GUI, and is no longer documented in this document; you will backup and restore at the NDFC level using the unified backup and restore functionality through the ND GUI instead. See the Unified Backup and Restore for Nexus Dashboard and Services article for more information.
