Among other things, I’m running a small Nextcloud instance on my home server and over time, data somewhat piles up (especially photos). My main storage is sufficiently sized & redundant for now, but I wonder how I am supposed to do a serious backup: The moment will come where the backup’s size will exceed any reasonly prized single drive. What then?
Of course I can just buy another disk and distribute the chunks, but that’s manual work - or is it not? At least
rsync has no builtin option for that.
Using a virtual, larger file system spanning among multiple drives looks like the easiest option, but I doubt it’s a good idea for a reliable backup - if one disk fails, all of the backup is gone. On the other hand: That’s true for the distributed chunks as well.
What do you people do? Right now I don’t have to bother as my data fits on a single device easily, but I wonder what in theory & practice is the best solution.
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 may have missed to point out that my server’s storage is my NAS. ;)
I realized that may be the case after commenting. I didn’t read your post as closely as I should have, but I kept the comment up in case someone finds it helpful.
Unfortunately I’m not aware of any solutions beyond buy bigger drives, stand up a backup NAS, or omit unimportant/non-critical/easily recoverable data from backups. I don’t think that’s what you’re looking for though.
Thank you nonetheless!
