Ever heard of CRYPTOWALL ? I think that I got it from
looking at PDFs on the
web while doing some research. It's a trojan, not a virus. It runs in the
background encrypting files. Then it pops up a message demanding 500 euros
for the key!
Sounds like Cryptolocker. Even the police paid the ransom to get their
data back.
At home I use an older Supermicro 15 bay 3u server as a NAS. I bought
every disk in a pair, and usually don't buy it in advance. Even though it
has a 24 port 3ware card, only the OS disk is mirrored, all the others are
exported JBOD (single disk, no RAID)
Then I manually run an rsync script here and there to copy the data from
disk set A to B.
Disk set A is the only one exported via NFS/SMB, so the only one the
Windows and Mac systems can get to.
Originally I was meaning to script it so the B disks would be spun down,
but haven't gotten around to that yet.
