setquota Mountpoint issue

Following a system restore my scheduled backups to Amazon are failing with he log/message:

Creating backup for virtual server domain-name.xx …
setquota: Mountpoint (or device) / not found or has no quota enabled.
setquota: Not all specified mountpoints are using quota.
at /usr/libexec/webmin/ line 1397.

Can anyone advise how to resolve this issue?
