Backintime doesn't support plain SFTP backends so it does not seem to be easy to setup a remote backup to a Synology Diskstation (in my case a DS214 with DSM 4.3).
Backintime supports SSH/rsync based remote backup but the Synology doesn't seem to allow automated SSH logins with trusted entries.
What is the best way to backup to a Synology NAS backend with Backintime?
So far, I could only manage a backup with mounting the Windows share to the workstation (with CIFS) and configuring Backintime as a local sync to the mounted folder. This works but I would like a solution which doesn't include Samba & Windows shares.
