SFTP ISSUE vs VERSIONING

[zed]

Hi

We have a profile, configured in exact mirror

LEFT SIDE ----> Windows environment,access samba \\IP\FOLDER
RIGHT SIDE ---->Linux Environment,access ssh-sftp

Everytning works fine, but when I activate in VERSIONING tab, the option to keep a back-up, I can not delete any folder-file in destiny if no exists anymore in source, also I can not make any bck.

Is a bug?
Hava I miss anything?
Thanks in advance
