World Backup Day 2011 is happening on March 31. As part of the global data-saving initiative, you are encouraged to back up all of your cherished photos and videos, and important documents. If you've ever had a hard disk fail, and not had a backup to fall back on, you'll know that it's a bit like losing a sizable fragment of your soul. If you've never backed up your important files -- or if you only back up sporadically -- do it on World Backup Day!
"A 2TB drive costs only a fistful of dollars, and it takes just a few minutes to set SyncToy for Windows, or Time Machine for Mac, to mirror your data every night. If you prefer a cloud-based solution, there's always SugarSync and Dropbox. Finally, don't forget that Bundlelytic has a charity giveaway for three excellent data-backup-and-recovery tools -- $160 of software for only $25, and 100% of the proceeds to go the Japanese Red Cross."
