From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I am using Borg for years. So far, the tool has not let me down. I store the backups on external hard drives that are only used for backups. In addition, I save really important data at rsync.net and at Hetzer in a storage box. Which is not a problem because Borg automatically encrypts locally and for decryption in my case you need a password and a key file.
Generally speaking, you should always test whether you can restore data from a backup. No matter which tool you use. Only then you have a real backup. And an up-to-date backup should always additionally be stored off-site (cloud, at a friend's or relative's house, etc.). Because if the house burns down, the external hard drive with the backups next to the computer is not much use.
By the way, I would advise against using just rsync because, as the name suggests, rsync only synchronizes, so you don't have multiple versions of a file. Which can be useful if you only notice later that a file has become defective at some point.
