Hello,

going to test incremental backup in 4.4.

Is this page the updated one to use:

https://www.ovirt.org/develop/release-management/features/storage/incremental-backup.html

This page contains a lot of data about the feature and includes must of the APIs but it still needs some updates.

There is currently no up-to-date documentation but we are working on it.

Please share your inputs when you have some insights.

You can have a look at the session we did on the DevConf 2020 conference [1]

Also, please note that in order to use the incremental backup feature you must set  'IsIncrementalBackupSupported'

to 'true' in the Engine database and restart the engine before taking a backup - 

engine-config -s "IsIncrementalBackupSupported=true"

 

 

?

Is there already any ansible module/role ongoing to support it?

There is no Ansible implementation for it but we provide a python SDK 

script for backup a VM using incremental backup new API [2]

Thanks,

Thank you very much for your insights, Eyal.

In the mean time I enabled the feature in the engine and I'm going to watch and read the resources you provided.
