Hello, Khang
If your intention is to backup the VM's volumes, you can use the
'Snapshot' feature on KVM, which will create a copy of the volume, this
can be done while the VM is stopped or running. With the
`snapshot.backup.to.secondary` configuration, the Snapshot will be
backed up to your secondary storage during the Snapshot process. Thus,
if you lose your primary storage, your secondary storage will still have
backups of your VM's volumes.
Furthermore, version 4.20.0.0 will come with some optimizations of the
snapshot process, as well as introduce the concept of incremental
snapshots when using KVM as the hypervisor; which tends to be a lot
faster and save storage space.
Best Regards,
João Jandre.

Hello everyone,
I'm looking for some advice on solutions for backing up VMs running on KVM
in Cloudstack. I found two plugins in the documentation, but they are both
paid. I also saw the dummy backup, but introductions to Cloudstack mention
that it is only for testing the API's functionality. Can I consider dummy
backup as a "native" backup solution for Cloudstack? I see two offerings,
'Gold' and 'Silver,' but there is no information on how many backups it
makes or for how long...
Can you suggest a backup solution for me or provide clearer documentation
about the dummy backup?
Thank you very much.
