As I see,
lxc export at first create backup at
/var/snap/lxd/common/lxd/backups/instances/<VM/LXC_NAME>/backup<#>, only then transfer it to the target dir.
Big VMs/LXCs that use much space are unexportable with mediator dirs, until I enlarge a pool with more vdevs. Also, backuping directly to the target dir will save time.
Can I force
lxc export to export directly to the target dir, to save time?
Data in my VMs and LXCs is not compressible, so compression is waste of time and CPU resources in my case. I started to use
--compression none, am I right?
I just noticed, that after installing LXD via Snap in Ubuntu 20.04, there is no manual for LXD/LXC.
man lxc returns
No manual entry for lxc.
