I would like an application to efficiently image my hdd -> compress -> upload to cloud backup. But I'll settle for just a cheap cloud backup so I don't have to compress it. I'd also like to encrypt the whole thing, so does anyone know of a good all-in-one solution there?
You could use Amazon Cloud Drive. Mount it with acd_cli or other tools. Mount any folder from ACD with EncFS (adds an encryption layer). Config the backup-app to write images to this folder. Let the compression be handled by the backup-app (acronis true image; easeus backup or other free tools). There are good unlimited cloud space providers that costs 5-6$/month - acd, crashplan, backblaze.
