Hello,

I have scheduled backup and one is related to the LXC 104.

As you can see: the backup of the VM 103 is ended and start the backup of the LXC 104 which have started 2PM:

Code:
INFO: Finished Backup of VM 103 (00:01:27)
INFO: Backup finished at 2024-02-29 02:09:56

INFO: starting final sync /proc/1735164/root/ to /mnt/usb/bkpvm/dump/vzdump-lxc-104-2024_02_29-02_09_56.tmp

I have to unlock the LXC, (pct unlock 104) to stop it and then to start it.
The config of the LXC:

Code:
root@pve:/etc/pve/nodes/pve/lxc# cat 104.conf
arch: amd64
cores: 4
features: fuse=1,nesting=1
hostname: srvtools
memory: 512
nameserver: 192.168.1.254
net0: name=eth0,bridge=vmbr0,gw=192.168.1.254,hwaddr=D2:65:25:32:80:E2,ip=192.168.1.180/24,type=veth
onboot: 0
ostype: debian
rootfs: local:104/vm-104-disk-0.raw,size=10G
swap: 512
root@pve:/etc/pve/nodes/pve/lxc#

If you have any idea where I can check things.

Thank you

Hi,
please note that you should not use snapshot or suspend backups for LXCs with FUSE mountpoints [0]. Try to perform the backup in stop mode or use the FUSE mount on the host with a bind-mount into the container [1].
