Maybe rsync is more suited to be run from command line while Unison (in addition to the command line) adds a GUI. > My idea is to have a external usb disk to avoid crashing/get lose > related with the machines that hold the data, but maybe is easier (and > as safe) if i just connect the disk (external or internally) to one of > the machines and issue rsyncs from there... via network.

That's what usually happens when "syncing" or "mirroring", each of the copies are keep the same but I think this can be customized, at least in Unison. Or maybe you need a backup/archive utility more than just a mere syncing approach. >> There are also package divertions aimed to be used for backup/syncing >> purposes that may include what you want out-of-the-box. > > package divertions? what do you mean? any that come to mind? "Divertions" → "variations" in Camaleon's parlance :-P Packages that while using rsync are targeted to another purposes (backup) like "rdiff-backup" or "back in time". > Also im thinking about encrypt the backup disk if is going to be around > and somebody can just steal it... any recomendations for this? (i never > used encrypted file systems coz im afraid if something is corrupted, is > going to be harder to recover) If the external disk is going to be used exclusively for holding data, I would go here for a complete disk encryption solution using luks or encfs.
