Back It Up, Buster!

Remote backups aren’t even remotely optional. Do it!

It still shocks me how many people don’t keep backups of their files. Every time people ask me to look at their computers (almost always a malware-infected Windows machine), I ask them if they have backups before I start poking around. Invariably, the answer is no. Sometimes the computers even contain vital business data, and the closest thing to a backup is a local copy of the database in the same folder as the active copy. As someone who had a house burn down, I can tell you, off-site backups aren’t just for fancy government organizations!

Things That Aren’t Backups

RAID (Redundant Array of Independent Disks), as wonderful as it is, must not be mistaken as a backup. Simply put, RAID is a method for ensuring your single, local copy of data is less prone to failure. And that’s really only for RAID levels that create mirrors or parity. Using RAID level 0, you’re actually more likely to lose data than by storing it on a single hard drive!
