Do you know a syncing tool which would work with a VeraCrypt image? (rsync algo doesn't for example)

- Groxx 3y agoRsync syncs only differing blocks of data (not whole files) by default - it's pretty much the reason it is so popular. There are a lot of ways to lose that though. No rsync able to run and calculate block checksums on the other machine -> no block syncing. Change a byte in a file in an encrypted volume -> it might copy-on-write and make a wholly new encrypted "file" with everything different in the final encrypted data. Etc, it depends on a bunch of stuff interacting in ways that they might have legitimate reasons to not support, particularly with security/privacy sensitive stuff. Not sure what you're encountering, but if it's important to you there are a few ways to troubleshoot it. It might be possible to get it working.
- zeroimpl 3y agoBy default if rsync sees any difference in metadata (timestamps), it just copies over the file fresh - first to a temporary file and then renames over the original. To do an in-place update you'd need to specify an arg for that. And even then, it needs to do a full read of both files to compare, so all it saves on is bandwidth.
- brokenmachine 3y agoSyncthing uses block syncing, so I imagine it would work well, although I haven't tried.
- aeyes 3y agoWorks fine with rsync here.
