How to managing and backup the backups?

1

Not related to F-droid itself, more about approaches.

Some apps can make backup of it’s data. For those data I created a directory “backup” in the internal storage with subdirectories inside, each directory for relevant app. (Is it good so far?)

Next step is to backup on cloud storage. What tools do you recommend? Synching?

One more thing is an encryption? How deal with it. As I understand I can’t use droidfs for example, because I won’t be able to open backup from cloud storage on PC. How to deal with this?

Appreciate your participation.

Added.
I’m ok with triggering backup sync manually, it’s even better.

Why do you need encryption when you use Syncthing to backup to your own secure server?

Possible with syncthing or any other cloud provider/client of your choice.

Try this on PC

I haven’t setup any backup yet. And it’s not my personal server (too hard to maintain) it’s will be just common cloud storage provider.

About syncthing the same I haven’t used it before much
