feat: simple "backup" function for a folder (including versions!?)

[mrustl]

[mrustl]

Maybe we can create a additional folder for each file with multiple versions:

test.docx/test_v2.docx
test.docx/test_v1.docx

This is all nice to have but not important now, I think. What we need first is the possibility to download a folder and all of its contents as a zip file (just as via the user interface). How is this done via API?

[mrustl]

Well the benefit of using kwb.nextcloud is that we have all metadata (which we will loose if we download it via UI as zip) I think.

simulating the ui download wouldb be:
https://docs.nextcloud.com/server/latest/developer_manual/client_apis/OCS/ocs-api-overview.html#direct-download

But then I dont see much added value if we do it programmatically....

[mrustl]

It would be enough to downlad the latest files frequently and add the "file-info" metadata to be able to reconstruct later if needed? What do you think?

[hsonne]

I think that a backup is (just) a backup.

[mrustl]

agree + plus one file metadata with content of recursive list_file_infos()

[hsonne]

That would be quite similar to KWB's MW-IT + pathana strategy

[mrustl]

Sounds good

Hm, I get the error: "Direct download only works for files"

>   str(httr::content(response))
List of 1
 $ ocs:List of 2
  ..$ meta:List of 3
  .. ..$ status    : chr "failure"
  .. ..$ statuscode: int 400
  .. ..$ message   : chr "Direct download only works for files"
  ..$ data: list()

Ok, I was wrong the zipfile capability is not offered by public API

Only found old documentation for PHP "OC" API which offers this:
https://docs.nextcloud.com/server/14/developer_manual/api/OC/Archive/ZIP.html?highlight=zip#OC\Archive\ZIP::getFolder

So maybe just run kwb.nextcloud::download_files(), "zip" it and finally add the file-info metadata?

The solution is 21...

Sorry, I was wrong. The solution is #31. @mrustl Would you like to review?
