@_elena Backing up, no matter how you do it, is important, what is even more important is that you test the restoration of your backups. There's a saying that says that an untested backup is no backup at all.
Also, I would recommend you look at restic over borg, as it's a more modern backup solution that has a very well audited encryption setup. Also, it's easy to setup with autorestic.
@ainmosni thank you for the feedback Daniël. May I add your advice to my blog post?

Dear sysadmins, you have all my respect and admiration, truly. One day I will learn how to do incremental backups with Borg, I promise.

@_elena Of course!
@ainmosni I'm looking after my little one who's home from school with a fever... will try to get to it ASAP.
Thanks again for the brilliant feedback

@_elena No rush, if I my executive dysfunction would ever let me, I might sometime write a blog post about my own self hosted setup.

Hi Elena,Just my 2 cents. I run Yuno for a lot off services. One is next cloud, which contains a lot of data (over 1 terabyte) If I use the yuno backup option I need a huge drive just to do the backup. So now I just shutdown the server, take out the physical nvme drive and connect it to my laptop. Then I use dd to make an exact 1:1 copy of the entire disk. This image is synced to different locations. Maybe this is useful to some folx. Thank you for your continued sharing.

That was my first comment too: you’ll have to test your backups otherwise you don’t know if you have backups
It’s a Schrödinger’s cat type of problem −> you have to open the box.And it leads me to a second aspect: automation. good backup processes (the one that brings piece of mind) are automated. And of course the backup check can be automated too.
It’s piece of cake for a backup solution that you can script (borg, restic, kopia, rsync, etc.) but frankly I don’t know about Yunohost, may be you can’t do better.On the side, I’ll share one of my sysadmin fails: I had a finely tuned backup process with scripts/config/etc. that was running daily for years flawlessly. Someday I leveraged that backup as a source of data to do a server migration (shutdown old system, start new one, restore data from backup). That worked great. Then I tested some web apps: epic failure (missing MySQL tables). What could have gone wrong?
Answer: I had setup my backup script to ignore files named*/mysql/*log*because I don’t want to backup MySQL log files. Not so much of a surprise: this element of config instructed my backup process to exclude database files named like dc_log.MYD or oc_login_address.ibd (and many others).
Of course I had another way to retrieve the missing data. But, hell, I was not comfortable. -
@_elena "Side note: I had to delete all my backups to simulate what the screen would look like for a new user and let me tell you... I was delighted to create a new backup right away (sigh of relief)."
...cue the suspense music from any decent horror movie.

> Fun fact - and sorry I'm addressing this point only now but the right way to pronounce "YunoHost" is Why-You-No-Host (Y-U-NO-Host). In the first couple of months of using the service I routinely mispronounced it YoU-No-Host.I have already learned something today and it’s not even 7a!

@_elena I laugh at your ‘trigger warning for sysadmins’ but also sadly know why you have to. I do hope it triggers some in a way that helps developers empathize with ‘normal’ people more, and work on sanding off more rough edges.
Thanks again for your posts. I think they provide a nice window to see how software works for other groups of people -
