[Owncloud] Owncloud service as a protection against ransomware?

[Erwin Rennert]

I see your point, but I advise against using OwnCloud as a backup 
solution. In my experience it is not nearly robust enough. Quite to the 
contrary, I am undertaking quite some effort to backup the data stored 
in Owncloud.

OC is great for sharing data, but it is not always stable and does not 
always behave as expected.

For protection from malware you are certainly better off educating your 
users and deploying AV software.
