This results in minimal downtime, but needs additional space to hold the container copy. - ++ When the container is on a local filesystem and the target storage of the backup is an NFS server, you should set `--tmpdir` to reside on a local filesystem too, as this will result in a many fold performance improvement. Use of a local `tmpdir` is also required if you want to backup in `suspend` mode a local container using ACLs to an NFS server. - ++ For QemuServer, this mode will suspend the VM, start -a live backup, and resume the VM. +a live backup, and resume the VM.
