Thx for your reply i need to test. Lxc export is taken from lxd 5.11 new server is running 5.16. As the old server luckly recovered .
I was using 5.11 as I was expirencing the bug/issue
I will test and let you know.
However it would be good to know how we can take LXC backups/export unrelated to any lxd version.
I was thinking of making images to avoid this problem, not sure its the best way.
