Bug Description

I set up sbackup 0.11.6 on Ubuntu Server 12.04 LTS.
I scheduled (as administrator) one backup of one directory via ftp.
I did a first full backup from user interface and i waited for next incremental backup after one hour (i scheduled an hourly backup)
After one hour i got this log error:

Using sbackup via ftp as user works perfectly, but when i disconnect user backup start with errors.
Is it a bug?

Thank you for using sbackup and reporting this issue.

It is a "kind-of" bug: sbackup uses GIO/GVFS as default backend to access remote location e.g. over FTP. The gvfs-daemon, in turn, is started via Dbus on user login, so it is not running without user session. For reference see http://ubuntuforums.org/showthread.php?t=1924017 Gvfs exports dbus services and thus should be actually started by dbus (see http://superuser.com/questions/228261/how-to-properly-start-gvfs-without-gnome)

As a workaround I suggest to use the FUSE backend implemented in sbackup. Please follow the instructions at https://answers.launchpad.net/sbackup/+faq/1326 to enable the FUSE backend.

HTH!
