# Backup and Restore

VeloDB Cloud supports backing up databases to object storage either
periodically or as a one-time operation, and allows users to quickly restore
data based on specified backup sets, comprehensively ensuring high
availability of data.

## Backup​

### Create a Backup Plan​

Click **Backup** in the left navigation bar, and click **Create Backup Plan**
on the Backup page. You can choose between periodic or one-time backups as
needed. Periodic and one-time backups have a mutual exclusion relationship.
Updating the backup plan will overwrite the original backup plan.

If periodic backup is selected, you need to choose whether to enable it, the
backup execution cycle, start time, backup objects, retention days, and the
cluster used for backup, and save the selected settings for them to take
effect.

If you choose one-time backup, you need to select the start time, backup
objects, retention days, and the cluster used for backup. Similarly, you need
to save the selected settings for them to take effect.
