![]() ![]() This is such a great example of the need to keep multiple backups in different locations. Even if the backup data is offsite – in a bank vault, for Heavens' sakes – that off site may be insecure. So all was fine because I still had my intact data back home and the backup HDD had just avoided a soaking but this was a lesson. The high water line around the vault stopped just below my strongbox so I was able to take out a still-dry and working HDD but a couple of inches more and it would have been soaked. When I went to collect my HDD for the weekly backup they were still pumping out the vault. The downhill rush of water washed away the roads connecting the village to the outside world and part of that water flowed into the bank vault. A few years ago there was a catastrophic storm. The bank with its vault is around 250 metres below us. Our village is halfway up a gently sloping hillside in a river valley. A Seatools check threw up an unacceptable failure rate of one of my external HDDS a few months ago and the HDD was scrapped.ġ00% sure. I regularly check my external HDDs with the free Seagate disk checker.A log of the backups is kept on a cloud server so that, when disaster strikes and I have to buy new equipment and restore images, I'll know what is where.I unplug everything if there is a thunderstorm in the vicinity or forecast, e.g.following creation of a large number of files. A second HDD which is kept at home is used for in-between backups during the week, e.g.Those files and all the other data on my PC and other office equipment are backed up weekly to an external hard drive (HDD) which is kept in the vault of a local bank conveniently situated 5 minutes by bike from my home. ![]() My priceless family photos and videos and music are kept on a network server with RAID redundancy.Several years ago a nearby lightning strike generated a voltage spike/current surge that destroyed my PC (the IT repair shop found one of the cards covered with Lichtenberg discharge figures and the HDD controller no longer worked). I assume that one day the burglars will come and take my IT equipment or the house will burn down or encryption malware will – despite my extensive anti-malware precautions – render my data inaccessible. I had a lot of responses to that newsletter, but here is a situation I’ve certainly never heard of from a DocumentSnap reader. Keep at least one copy in a different location. Store 1 backup offsite – Whatever happens to your computer could happen to your backup drive too.What happens if you no longer have a CD or tape drive? If you’re old like me, you’ll remember ZIP drives. Keep these backups on 2 different media – Don’t have your originals and your backups on the same drive.Have at least 3 copies of your data – In other words, have your original PDFs (1 copy) and 2 backups (2 more copies to make 3).The general concept is that you want your data in as many places as possible: Recently on the DocumentSnap newsletter I wrote about an important concept in protecting your paperless documents: The Rule of 321. ![]()
