Backup and restore

Use the Backup And Restore screen to create a backup of the appliance, or to restore an appliance from a backup.

● Before you backup or restore an appliance, for each installed plugin, ensure you have read and complied with the limitations and requirements in the Manage backup and restore for plugins section of each plugin's User's Guide .

● Before you backup or restore an appliance, ensure that the system is stable, that is, there are no critical alerts on the appliance. For scheduled backups or restores, choose a low-volume time frame to lower the risk of critical alerts.

● You cannot Migrate an appliance in this version of OpenManage Enterprise. This option is included as infrastructure only in this release, and it will be documented in detail in a future OpenManage Enterprise version, as soon as it is relevant.

CAUTION: Only one backup / restore process is supported at a time. Running more than one backup / restore process at a time can lead to unexpected system behavior.

Restricted

The default state of the OpenManage Enterprise appliance. In this state, all features provided by the appliance are accessible and fully functional.

A banner is displayed at the top of the OpenManage Enterprise GUI when the administrator begins the backup process or the scheduling process initiates the backup based on a predefined schedule.

A banner is displayed at the top of the OpenManage Enterprise GUI when the compressed backup file (including both OpenManage Enterprise and plugin backup files) is ready to be streamed out. The appliance must be in this state before the actual streaming operation can be activated.

Backup an appliance

Use backup jobs to store appliance data like resource allocation, CPU, memory, system configuration and plugins.

Prerequisites

● Ensure you are a root (backup) administrator, as described in

User roles

.

● Ensure there is enough storage space on the target appliance.

● Ensure all installed plugins are enabled.

● Ensure FSD is disabled, as described in

Disable FSD

.

● Ensure the Backup / Restore Settings are configured, as described in

Manage console settings

.

● Terminate currently running jobs or wait for all running jobs to complete.

● If the backup location is a local network share:

188 Backup and restore

○ Ensure OpenManage Enterprise has both read and write access to the share, as described in

Enable read and write access to your network share

.

○ For backup files over 4GB, use CIFS or NFS share types, as HTTPS shares have a 4GB limit.

○ For HTTPS shares, ensure the Destination Path does not contain encoded characters.

For example: https://100.100.100.100/backup%20and%20restore/ is not supported.

About this task

● During a backup:

○ The appliance is in Maintenance state. During this time, all new task scheduling is suspended. Only administrators are able to log in and all write operations targeting the appliance return an error. No operations can be performed on the console during this time.

○ All other users are logged off and unable to take action until the backup is complete.

● The Technical Support Report (TSR) and diagnostic reports are not included as part of the backup process. The TSR and diagnostic reports are stored in: ../shared/dell/omc/cifs/idrac/tsr/ .

Steps

1. Click Backup / Restore > Backup .

2. Select the Backup Location :

● Select HTTPS in you have an HTTPS share, and enter the:

○ Destination Path to where your backup file(s) will be stored.

○ Username used to authenticate the share.

○ Password used to authenticate the share.

● Select CIFS if you have a CIFS share, and enter the:

○ Domain on which the share is hosted.

○ User used to authenticate the share.

○ Password used to authenticate the share.

● Select NFS if you have an NFS share, and enter the Destination Path to where your backup file(s) will be stored.

3. Optionally, enable Backup File Encryption by entering a Passphrase that will be required in order to recover this backup.

4. Optionally, change the value of Set Schedule to configure the automatic backup process to Run Now , Run Later , Run On

Schedule , or set it to Off .

NOTE: Best practice is to select Prerequisites > Running Tasks > Complete Running Tasks Before Running

Backup for scheduled backups.

5. Click Run Backup .

Results

A backup job is initiated. The backup is created in the specified location and can be used to

Restore an appliance

.

Next steps

During backup, you can click Abort Backup to stop the backup at any time.

NOTE: Abort Backup fails when the appliance is in Maintenance Pending state.

Restore an appliance

Restore an appliance from a backup to reinstate an appliance data like resource allocation, CPU, memory, system configuration and plugins after updates or major configuration changes.

Prerequisites

CAUTION: Restoring an appliance overwrites its data, and this action cannot be undone in OpenManage

Enterprise. Best practice is to take a snapshot of target appliances before you restore them.

● Ensure you are a root (backup) administrator, as described in

User roles

.

● Ensure the restore location is registered.

Backup and restore 189

● Ensure FSD is disabled, as described in

Disable FSD

.

● Ensure the Backup / Restore Settings are configured, as described in

Manage console settings

.

● Ensure the OpenManage Enterprise and plugin versions on the source and target appliances are identical. If they aren't, update them as described in

Updating the console and plugins

.

About this task

After restoring backups with plugins, a plugin synchronization job may start if there are plugins installed on the source appliance that are either not installed, or disabled, on the target appliance. Since firmware bundles are not part of the backup file, any firmware update will cause the re-download of catalog files for the upgrade if the task was triggered by a baseline.

Steps

1. Click Backup / Restore > Restore .

2. Display the list of available backups:

● Select HTTPS in you have an HTTPS share, and enter the:

○ Destination Path to where your backup files are stored.

○ Username used to authenticate the share.

○ Password used to authenticate the share.

● Select CIFS if you have a CIFS share, and enter the:

○ Domain on which the share is hosted.

○ User used to authenticate the share.

○ Password used to authenticate the share.

● Select NFS if you have an NFS share, and enter the Destination Path to where your backup files are stored.

3. Click Test to validate the appliance's access to the destination path.

4. Click Apply to display the list of backup files available on the device.

Select the checkbox to Only show backups generated by this appliance .

NOTE: Backups generated from the same appliance can be deleted.

5. Select the required backup file.

6. Enter the Passphrase required to de-crypt th backup file.

7. Click Restore .

Results

● A restore job is initiated on the target appliance.

● An active backup job is displayed while the restore job is running.

● The target appliance is overwritten and cannot be restored.

● Once restoration is complete:

○ the backup job is stopped.

○ the restored appliance reboots.

○ when the restored appliance is up and running, all group discovery and regular discovery jobs are initiated.

Next steps

● Upload the Dell Update Package (DUP) to the restored appliance.

● Check for running or failed plugin synchronization jobs in the api/BackupRestoreService/

RestoreExecutionDetails response.

● While services are being loaded, do not trigger multiple executions of the same job through the Jobs screen.

● If the source of the backup file is not the target restore destination:

○ When restoration is complete, shut down the source appliance.

○ Recreate the source appliance configuration on the target appliance, as described in

Configure the system using the TUI

.

○ Ensure the restored appliance is registered with an FQDN in the DNS settings.

○ Update static routes to the restored appliance network.

○ Upload your custom certificate to the restored appliance.
