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.

Hi,
ransomware gets more and more widespread. If your windows workstation
gets infected with a version of this malware type, all your data files
(local or stored on the network) get encrypted and you need to pay to
get them decrypted again. For more info see:

Of course the real and only reliable solution is to backup your valuable
data. However, I think using owncloud may give some level of protection
to my users (at least for the time being). So my question is:
Am I right to suppose that when the ransomware encrypts the files that
are either synced to owncloud or when owncloud is used as a network
drive through WebDAV: the automatic versioning of owncloud retains the
unencrypted version of the files?
If the answer is yes, it could be very useful to develop a script that
automatically restores all files to a state before a certain timepoint
and nukes any version stored after that timepoint.
By the way, does any owncloud admin have any real experience with a
ransomware infection?
Yours: Laszlo
