I help a school with their tech needs including a 2 bay Synology NAS unit. Yesterday, one of their PC's got infected with Cryptowall. In addition to encrypting local files, it also encrypted any of the shares that user had access to on the Synology Diskstation.
Thankfully I had a cold (disconnected) backup of the Synology NAS from two weeks ago. Not much was lost. We will continue to keep a cold storage hard drive off premises for a number of reasons.
Is there a automated hot backup strategy that might have kept safe daily or weekly backups? Maybe backup the diskstation shares to an external usb 3.0 hard drive connected to the synology and retain a few different backup sets. week 1, week 2, week 3, week 4 and they would get copied over the first, second, ... week of each month. More importantly, as long as those are not mapped to any computer on the network, would they stay safe from crypto locker/wall style attacks?
Thanks for your guidance. Sean
