lvm in new setup

[elkondor]

i need to setup new machine with 6.2 i have old 4.4 with machine without lvm-thin storage and vm in qcow2 file and no lxc.
now i interesting to use lxc together kvm.
if i set no lvm-thin storage, with new version is possible to backup lxc machine in non lvm-thin storage situation or not?
because i prefer qcow file management for backup/restore.

what are the advantages of using only lvm-thin for all?

LXC containers can not be put in qcow2 files, if that's what you're asking. You don't need to use lvm-thin for everything, but if you do, then VMs and CTs can share the thin-provisioned storage.

I know how lxc works.
but I ask if compared to a time, lxc can work on classic lvm (old classic disk file for vm machine) and take snapshots without interruption,
because kvm/qemu can snapshot in some mode and storage type

(sorry for my english)

See our storage documentation for which storages support snapshots: https://pve.proxmox.com/pve-docs/chapter-pvesm.html#_storage_types

If snapshots=yes in the linked table, then containers on that storage support snapshots as well. They won't be interrupted, but in comparison to VMs they only support file-system snapshots, so RAM state cannot be saved.
