Dust accumulates in this corner about once a week. Maybe there is some kind of a vortex of air and dust particles that causes it to accumulate at an unnatural rate. In any case, I know that I must sweep it up or eventually there will be a dust pile that will take over the house.
Similarly, there are tasks we need to do regularly or we may pay the price. One price that might be huge relates to your data. When was the last time you backed up your data? If it wasn’t this week, think of the time you would lose if your hard drive crashed.
Solution? Easy. Buy an external hard drive.
Mac: Attach the drive and it will walk you through Time Machine, a built-in program. Apple has instructions here, if you need help.
Windows? Just about any external hard drive comes with a program to do automatic backups.
My recommendation is to leave the drive attached and let it do your backups regularly.
A word of caution: if you think your computer is too new to require this precaution, think again. My brother’s hard drive died last week after just 18 months.
