I’ve set up a public share that contains PDF and media files frequently accessed by the members of my choir.
Some members asked if it’s possible to use the Nextcloud app to sync this share on their device, so they can access files when they’re offline, or if my server is temporarily unreachable.
So far, I think this is not the goal of the Nextcloud app. But I’ve not found any suitable application for this use case.
The problem is perhaps that WebDAV is actually an online access and does not provide for a copy at all. With Nextcloud, a Nextcloud client (download) is therefore actually used for this case.
Of course, you can also combine davfs2 with rsync on Linux, for example. This is not really great and probably not an option under Windows.
What you can perhaps do if you don’t have too much data is to add /download e.g. https://cloud.server.tld/s/abcdefghijklmno/download to the share and then download all the files as a ZIP file. This can be used locally offline. The disadvantage is perhaps that there can be no incremental offline version. You always have to download the ZIP file again if you make changes in Nextcloud.
But perhaps you can divide the data into several folders (zip files) and also set an update time for your users (e.g. once a day). The folder name could also contain the date and time so that you can clearly recognise how up-to-date the data is.
One goal of the Nextcloud app is to use offline Nextcloud data.
The Nextcloud Android app makes accessing, syncing and sharing your files easy with its modern and intuitive interface.
The problem is rather that perhaps not all users want to install a Nextcloud client and synchronise the data in it. The regularly updated ZIP archive could therefore perhaps be an alternative. But of course you can offer both.
