In this link
https://ovirt.org/documentation/admin-guide/chap-Backups_and_Migration.ht...
in point 4 it is said that
4 .Attach the snapshot to the backup virtual machine and activate the disk:
POST /api/vms/22222222-2222-2222-2222-222222222222/disks/ HTTP/1.1
Accept: application/xml
Content-type: application/xml
<disk id="11111111-1111-1111-1111-111111111111">
<snapshot id="11111111-1111-1111-1111-111111111111"/>
<active>true</active>
</disk>
What does this 22222222-2222-2222-2222-222222222222 mean do we need to
create a new virtual machine and attach the snapshot to that.
Could you kindly explain it further
The 22222222-2222-2222-2222-222222222222 is the ID of the VM that the
backup solution runs. You will need a VM that does the actual backup. This
is the "Backup VM" copies the data from the other vm disk snapshot and
stores it somewhere safe. Other VMs snapshots will be attached to this VM,
which will do the backup, then detached.
If the Backup VM is doing the API requests, it can get its UUID by looking
for itself via the API or via dmidecode (UUID field).
