How to clonezilla efficiently a LVM volume?

I have a Debian 12 system that I want to backup using clonezilla. This system is using LVM and a bunch of little partitions. Some using ext4, and some in xfs. The issue, is that, if I don't do anything special, and use exclusively the gui, clonezilla stop the lvm manager before doing a backup and switch to raw mode to save the disk. Resulting in a quite long backup process and quite long restore process. The image is small compared to the disk size (512GB save to a 17GB file). Why clonezilla don't want to save each lvm partition ? Do I have to ask clonezilla to backup each lvm partition, and use a custom restore script where I create the lvm volume myself before issuing a bunch of restore commands ? Is there a way to make this backup more efficient ? Best regards.
