Just over a week ago my laptop started giving me warning messages saying that a fatal drive crash was imminent. I talked to Dell who started walking me through diagnostics, and then quickly stopped listening to the diagnostics and started arranging for a new hard disk drive. It arrived on Monday, and now (late on Friday afternoon) I think I am about done with installing software and restoring it to where it was. Oh, and extending my warranty just in case.
I was able to carry on working on other computers, and because as soon as I got the error messages I backed everything up to an external drive. Which I copy to another external drive, and store each in different buildings - though if the whole town blows up I am in trouble.
I know it is a cliche, but really - if you haven't backed up recently, do it now. That is
now! The interuption to your business could be fatal.
One thing I use that helps is Dropbox - see
here. This is a free web based utility that makes it easy to sync files between computers, and your phone. It also acts as a backup for your documents, so you don't lose them if your HDD crashes. There is a paid for service, and it used to be that I could get more free space if I invited you to join, but really this is a public service announcement not an advert.
Back up now. Just in case.
