Backups and Ransomware

This week we lost one of the hard drives in our NAS drive (Network Attached Storage).  This is the device which we backup all our data to on a nightly basis.   This meant we needed to replace the drive and while we were at it we decided to review our backup strategy.

My really essential files such as my Family History research live in Dropbox,  which has an automatic backup option, all my data including my 60,000 plus photos are backed up to the NAS drive mentioned above every day using Syncback Pro.  This works well and makes it easy to recover a file if I accidentally delete it and notice before the end of the day.  Additionally we have 3 external hard drives, which come in every week or so from the fire safe in the garage and these also contain copies of our data.  So if we should have a fire or similar problem which destroys the NAS and the computer we can go back having lost only a week or so’s data,  if we have been away we tend to backup to the external as soon as the photos are loaded on to the main computer.

For our boot drive this is backed up using the Acronis Drive image backup three times a week so it’s easy to recover windows if it has a bad day!

Now. . .  In the advent of the new aggressive ransomware, such as hit the NHS here a little while ago,  I thought we ought to improve the security of the NAS drive to prevent it being overridden by a virus which made it past my firewalls and anti-virus,  so what we have done is to modify the NAS so it can only be read by the Windows network and to write to it you need to use FTP and a different user from that which the PC is logged on with.

So hopefully this will prevent the loss of the data on the NAS in the event of an attack.
