Some time ago, I wrote up my data protection strategy.
I’m no longer using most of what I describe in that article for two
reasons:
- For various reasons, we
are now using Windows as our primary laptop computing platform.
- Backing up to an external hard drive is not robust against
ransomware such as CryptoLocker that
encrypts your files and holds them hostage until you pay the criminal or
organization deploying the attack.
This second point is particularly important: in addition general
practices to keep from running ransomware (or other malicious software)
in the first place, the best protection against CryptoLocker-style
attacks is a good backup strategy where the backups are kept out of
reach of the backed-up system. These attacks typically try to encrypt
all the data files they can find, including on external drives and
network shares, so if your backups are stored on such a drive they’ll be
scrambled too.
However, if you have good backups out of reach of your computer, and
you get hit, you can recover relatively easily: reset the computer from
install media, restore data from backups, and go on your merry way.
Being careful, of course, to avoid opening potentially-malicious files,
as it’s quite possible that the infection arrived through some document
that is saved in your backups.
