Disaster Recovery
We have spoken about computer backups in the past in this column, and there are some things that you just can’t remind people of enough! However, some recent experiences have encouraged this column to be on more than just backup, but total disaster recovery.
Most large corporations have what is known as a ‘business continuity plan’ which basically covers how the business can make sure that it can keep the doors open, even in the face of a catastrophe. Usually, the plan is a mixture of backup, redundancy and preparation: multiple, regular backups of all critical data; extra pieces of computer equipment as spare in case something breaks; and planning and communication to all staff to ensure that best practice is followed.
There is a lot the average home user can take from these plans. With the price of external hard drives so low these days, there really isn’t much of an excuse to not be backing up your critical files and photos regularly. But backing up isn’t just copying to a hard drive. Make sure you follow the 3-2-1 model – 3 copies (1 primary, 2 backups), 2 on different formats (e.g. hard drive and DVD), with 1 copy stored offsite (including online).
Also think about the less obvious outages: what happens if you lose your internet connection? Do you have a backup dial-up modem? How long can your home business run without email? Do you have paper copies of really critical documents in case the digital copies were lost forever? Do you test your backups to make sure they’re ‘good’?
The best time to plan for a disaster is well before it happens. So we suggest you hop to it!
