Hi.

After install s3-f3 and mount s3 storage container does not backup. LXC contaiter freezes, backup task not ended.
unmount s3 storage solves problem.

Hi,
yes, this is a known issue: https://pve.proxmox.com/pve-docs/chapter-pct.html#_fuse_mounts You'll need to use stop mode backup or not use FUSE mounts.
