Yes, we know that there is now a world day for just about everything, and March 31st is World Backup Day (
@WorldBackupDay for the ‘twitterati’ amongst you). There is a point to this, how many of us have never, ever, lost data for want of a backup, whether it be photos, a report, music. And increasingly we are doing more and more online, eBooks for example.
The World Backup Day website http://www.worldbackupday.com has some good advice, as well as games and other stuff.
Worth a look!
