Safety from cryptoviruses

[ig0r]

A friend was using Dropbox as a backup solution when his computer got attacked by cryptovirus. All his files got encrypted. He wanted to restore them from Drobpox historic versions of the files, but they were allegedly encrypted as well.

How is it with the safety from such cryptovirus attacks in Seafile? Are in case of such attack historic (snapshot) versions affected as well or can one easily restore them to their corrupted/unencrypted versions? Does it make a difference if one is synchronizing files via Seafile client or if one has mounted Seafile as a network drive? What I'm asking is, if there is any way, that old versions get affected form changes caused by cryptovirus.

A cryptolocker type malware can't encrypt old versions on Dropbox as there is no ability to access them. If he was using the free version though only the last 30 days of versions are kept so if it took more than 30 days to realise thenyeah it might be un recoverable.

A cryptolocker on a users machine wouldn't be able to do anything to seafile but one on the server could.
