If you want bare-metal backup and restore to work, DON’T exclude /dev and /proc or you will probably have to mkdir them from your live-cd restore environment before your system will boot as expected.
I run fsarchiver from the live system with no LVM (but I’m not running any databases like *sql) and it has been stable for years, countless restores to P2V with no issues - except before rebooting into the restored VM, you should modify certain files in /etc such as:
/etc/network/interfaces , etc/rc.local , etc/hostname , etc/hosts. And /etc/fstab if certain drives that would otherwise automount are not included in the VM.
Systemrescuecd** has fsarchiver built in and has been very handy for doing P2V to VMs and occasionally restoring bare-metal if an upgrade went sideways.
** distrowatch dot com/table.php?distribution=systemrescue
Regardless, always test your restores - in a VM if possible, otherwise to an external bootable USB or separate internal drive. Fsarchiver has proven more useful than tar because it stores all the metadata by default as part of the backed-up filesystem. (And it has compression and multi-cpu support.). It’s a wonderful free backup program for Linux.

Hello!
How are you?
We use OMV NAS, it has backup plugin with fsarchiver option. The process get no errors. I do not know if when I did try restore the backup breaks something, because when try to restore to new disk device the omv system does not boot anymore. What are my errors to restore process?
Thank you!
