I prefer restic for my backups. There’s nothing inherently wrong with just making a copy if that is sufficient for you though. Restic will create small point in time snapshots as compared to just a file copy so I’m the event that perhaps you made a mistake and accidentally deleted something from the “live” copy and managed to propagate that to your backup it is a nonissue as you could simply restore from a previous snapshot.

These snapshots can also be compressed and deduplicated making them extremely space efficient.

Just look at the bit rate of what you are streaming and multiply it by 3 then add a little extra for overhead.

What exactly do you mean by “not mountable”?

Use the absolute path to the file instead of a relative path.

Debian for all things.

Add a test folder, add some data, delete the test root folder and see if it deletes the data.

Error message? Nextcloud logs?

Can’t tell you whats happening without information about what’s happening other than “it doesn’t work”.

If I’m supposed to be reading that top comment I don’t see where you state what your results were. You apparently “had errrors” but neglected to note any down and now “you don’t” have errors.

This it should be no issue for you to copy and paste that answer in our conversation.

And what exactly happens?

You tried what exactly earlier today?

I do exactly this as well.

Why not just run a reverse proxy container on the server hosting the rest?
