Since I discovered BorgBackup (short: Borg) I have felt way more confident about my backups. Borg gives you a space efficient storage of backups, data is saved encrypted, and you get good versioning of backups. I solved all my previous inconveniences when just using rsync. I lacked the way to keep track and order different versions. Compression and encryption as a great plus even when I just keep my backups locally.
It has been a very complicated year regarding my cloud services. I started completely unaware of the difficulties, and it has been a fun and painful ride. The fact that there are projects aiming to provide personally controlled cloud services is great. The fact that there is people being paid for doing this kind of work for companies means that it ain’t that simple to manage. I encourage to try the sovereign project, which assists you in building and maintaining your own private cloud.
