Evergreen backup

[thbenner]

Hello,

I would like to realize a kind of evergreen backup

1) The target disk holds all files which once have been on the source disk.
2) If a file is deleted on the source disk it should not be deleted on the target disk
3) In order to avoid duplicates a file or directory which is moved on the source disk it should also be moved on the target disk

Is there a tool or a set of tools that can handle this automatically. I didn't find a sync or backup app until now which can handle all three points.

You would want to use 'update' as your sync method, but it will not detect moved/renamed files
