So.. just upgraded my eol omv3 to omv4.
I had a bunch of rsync jobs setup to push data.
It worked like a charm.
I pushed subfolders of a share to another omv installation.
But I didn't not down my config... big mistake.
Now I am trying to remember how I got rsync to only sync subfolders of a share and I cannot remember..
Any clues...? No matter what I do to the source shared folder entry it just reverts back to the main share...
