I think that's the only point you made I actually disagree with. Rsyncrypto was built so that you can recover your entire data set using a single private key that need not be updated. Just make sure you store that securely (say, on a DoK in a safe, or whatever), and you can lose the entire local data and still recover everything. You can even post the private key, password protected, to the same place you back everything else up. Not having an on the fly mode ... but, on the other hand To where do you backup your data offsite?  rsync.net is great, but relatively expensive at rest compared to object store cloud offerings like AWS S3's lower classes and Glacier, Backblaze B2, Azure's archival offerings, etc.  Rclone would appear to be the equivalent program for those, with its own limitations, including greater bandwidth use. But on the fly mode would, pretty much by necessity, be incompatible with current rsync. This means that even fewer backup providers would be eligible. When originally written, rsyncrypto was meant to be the technological side of a backup service I intended on running. On the fly would have been acceptable there (but would have reduced its usability to everyone else). The power of open source is that the technology lives on where the business has failed, but I guess even that has its own limits. Ah, that brings up a 4th: rsync/rsyncrypto shines for files that have small portions changing, like log files, but today for many if not most users that's minuscule compared to media files that don't get changed.  Compare to people with only a few computers to back up not finding deduplication compelling, because storage and bandwidth costs and capacities have changed so much. Like I said, the world has moved on. I accept it. It's why you're not seeing new versions coming out. Shachar
