You may also want to check mondo:

I am using it for many years, since CentOS 5 (until now with CentOS 8).
There may be a few glitches, but otherwise I am pretty satisfied.
It supports bare metal recovery and can be used for cloning too.

Hi, while relax-and-recover, mondorescue and similar tools have their
place, I mostly find them outdated for VM backup. The main reason is
that they have difficult providing low RTO and RPO.
For my current low-cost linux hypervisors I use a ZFS filesystem, with
backups done leaveraing a mix of both ZFS send/recv and rsnapshot. More
specifically:
- rolling hourly snapshots are taked via sanoid;
- the primary datastore (with raw disk images) is replicated with 1min
interval (thanks to send/recv) to a second, standby server. This
guarantee a byte-for-byte copy of all the virtual machines backing files
*and* the capability to quickly restart all VMs in case the first server
dies;
- a third machine does rsnapshot-based backup of the data inside the VMs
themselves, for added convenience in recovering a single file and for
longer historical retention.
This backup scheme as served me very well.
Just my 2c.
Regards.
