Can anyone think of a reason I would NOT be able to manually install and run the FreeFileSync/RealTimeSync (FFS/RTS) Linux tarball in OpenMediaVault? My Linux Mint and Kubuntu FTS/RTS installs are both manual -- the only way to get a current FFS/RTS release in those and most other distros. I'm guessing there shouldn't be a problem in any (most?) Debian-based distros, either, but I figure it's better to ask upfront than be disappointed later on.
BTW, I have years of experience with FFS/RTS and none whatsoever with rsync, which is why I ask. Besides, FFS does bidirectional syncing and it's my understanding that rsync doesn't.
