1.3. Restoring MicroShift data backups manually
You can restore MicroShift data from a backup manually. Backups can be restored after updates, or after other system events that remove or damage required data. Automated backups are in the /var/lib/microshift-backups directory by default. You can use this directory for manually backing up and restoring data by specifying it in each command. When you restore a backup, you must use the entire file path.
On an rpm-ostree system, MicroShift backs up and restores data automatically.
Prerequisites
- Root access to the host.
- Full path of the data backup file.
- The MicroShift service is stopped.
Procedure
Manually restore MicroShift data by using the full file path of the backup you want to restore by running the following command:
$ sudo microshift restore /var/lib/microshift-backups/<my_manual_backup>Replace
<my_manual_backup>with the backup name that you used. Optional: You can also restore automaticostreebackups using the full file path.Example output

Manually restore data from a customized directory by using the full file path of the backup. Run the following command:
$ sudo microshift restore /<mnt>/<other_backups_location>/<another_manual_backup>Replace
<other_backups_location>with the directory you used and<my_manual_backup>with the backup name you used when creating the backup you are restoring.- Restart the host. Restarting the host enables all workloads and pods to restart.
Verification
-
Use the
oc get pods -Acommand to verify that the cluster is running, then check the restored data.
