Let me set some scene first.
I have a VM install from this repo (which is affiliated somehow with nextcloud developers, right?).
My installation is close to vanilla setup (except for a 2FA plugin, but I doubt that this matters) and planned to be used for home file storage.
I’m setting up automatic backup to a cloud storage and I could really use some space savings, even small ones =)
So, what files and folders of nextcloud data folder are safe to exclude from my backups? Right now I have these one excluded:
/mnt/ncdata/appdata_*****/preview (looks like a folder for image previews)
/mnt/ncdata/nextcloud.log (logs are useful, but not in backups, at least for me)
/mnt/<username>/uploads/ (looks like a temporary folder for user’s unfinished uploads, which I don’t really need as well)
Are these safe to exclude? And maybe there are more folders that I might filter as well?
