Maybe you could call it Sinker.
You have me interested, reinventing the wheel is often a good thing.
I am a little unclear about your intended functions.
Could you outline that for me please?
I have been using LuckyBackup for quite a while, mainly backups (incremental and accumulative), between several computers. Also occasionally for synchronizing folders to reduce unwanted redundancy. I was using it in combination with Dropbox and Mega... the cloud segment was always kludgey.
Recently (a few months ago) I added Syncthing to the mix, and dropped Dropbox entirely. That is now working smoothly, but I am still tweaking it.
