VPS backup? (lemmy.ml)

I've returned after taking into consideration everyone's advice on what I should do with my basic VPS and.....listened to none of it for reasons. Well, I had a good reason. I wanted to diversify my internet consumption with all this Reddit API mess and have gone back in part to RSS. In that vein I have stood up Minflux and Wallabag on said VPS. Both are excellent if you need a RSS and a read it later app. And they can tightly integrate with one another which is rad.

So now that I've got it set up the way I want, what is the recommended method for backing it up in case of failure/data loss? It's running Ubuntu 20.04, if that helps. I have Google drive space as well as Backblaze B2 I could leverage. I just need to know which direction to look for solutions. VPS is rented through Racknerd and I confirmed they don't have snapshot function unfortunately.

You should do application level backups and put those in backblaze b2:

for postgres look here.
look at all the software you’re running and what they say about making backups.
for files that don’t change often, making a an archive (with tar) is probably good enough. But if it changes during making the archive, the backup will be inconsistent.
think about your RPO: how much data are you willing to loose in case of a crash? 1 day? 2 hours? 15min? Schedule your backups to be at least as frequent.
Don’t forget to test your backups! Otherwise you’ll only find out that the backup is unusable when you need it most…
