(That page has some coupon codes for backup services, plus apparently there are some Twitter contests to win free backup packages. Smart marketing!)
If your computer isn’t backed up, consider this a friendly public service announcement reminding you that you might want to take care of that soon-ish.
And don’t forget to back up your website(s) as well — in the case of WordPress, you need to back up both your database and your actual website files in order to have a complete copy. There are several plugins that will do the job (I use a combo of WB-DB Backup for my database and WordPress Backup for my files, and there are plugins that will do both parts, but I haven’t tested them yet).
I’ll also remind you that there are a limited number of slots still available in my WordPress Peace of Mind Program, which is open for new signups until April 4. If you join this program, I will do a complete backup of your site (and schedule regular ongoing backups) as well as upgrade WordPress, your plugins and themes.
And I had no idea World Backup Day was going to happen during the enrollment period!
