Sort of an odd issue; I have an LXC Debian container and it fails to do backups when the mode is set to Snapshot. It tries to fall back to Suspend mode but eventually that fails. I was successful in running a backup in Stop mode, but that's not ideal as it turns the container off for a period of time.
Any ideas? Thank you for any help!
