I'm on a mac. Is there an easy way to encrypt my data before it's uploaded? Would an encrypted image, permanently 'open' on my system suffice?

- IAmEveryone 9y agoThe encrypted image would theoretically work. Practically, I'm pretty sure iCloud cannot do differential backups and any change to any file in the image would require a complete re-upload. I actually wouldn't have a problem trusting Apple's promises on data privacy. Unfortunately, iCloud Drive is not yet encrypted end-to-end, unlike messages, keychain, photos and some other content. They're supposed to be working on it.
- C14L 9y agoThere is `rclone`, a command line tool a little similar to rsync, that supports many cloud storage providers. It does diffs too. https://rclone.org/ https://rclone.org/
- mercer 9y agoI just realized that I already have an encrypted volume stored on Dropbox, so I did not need to ask. But to answer yours: I'm not 100% sure about iCloud, but at least Dropbox seems to have no trouble uploading only the changes of my (large) encrypted volume, whether it's mounted or not. I have run into problems, however, when I mount the image on multiple computers, so I'd recommend against that, or at least making any changes before everything is properly synced.
- kccqzy 9y agoYou can use sparse disk images so that your encrypted content is stored in chunks as little as one megabyte.
- innocentoldguy 9y agoThis may not be what you're looking for, but I've been using SpiderOak on my Macs for about five years. SpiderOak encrypts all your files and syncs whatever folders you want it too seamlessly. I use it to keep the files on all my Macs in sync.
- mercer 9y agoThanks for the tip! I'm currently okay with not syncing everything, and for backups I'm quite happy with Tarsnap. But there might be a time where I do need to sort this out.
