If you want to backup virtual machines at a given point in time, you can trigger an on-demand manual backup for an OpenStack virtual machine. After the manual backup is complete, the next backup happens as per the schedule defined in the backup policy.
Considerations
Manual backups ignore backup window restrictions defined in the policy and run until completed.
Manual backups consume all available bandwidth and do not apply policy bandwidth throttling limits.
Before initiating a backup or restore, the system checks current usage against absolute limits to evaluate the target project's quotas. To proceed, the available quota (Total Project Limit – Current Project Usage) must meet the following requirements for Backup Operations (Cinder Project Quotas).
To successfully back up a virtual machine, the target project must have sufficient Cinder (storage) capacity available. For a VM with
nvolumes and a total allocated disk size ofxGB, the project quota must have:Snapshots: At least
navailable snapshots.Volumes: At least
navailable volumes.Storage (Gigabytes): Available capacity equal to at least twice the total volume size, plus an additional 10% grace margin:
Required Storage Quota - (x * 2) + 10%
Procedure
Log in to the Management Console.
Select your Organization from the top menu bar (if applicable).
Navigate to Protect > OpenStack.
Select the target project/region from the left navigation pane.
In the left navigation pane, click Configured VMs.
Select the checkbox next to the OpenStack virtual machine(s) you want to backup.
Click Backup Now and confirm the prompt.
The backup job initiates immediately. You can track progress, and status on the OpenStack All Jobs page.
