Today, we celebrate World Backup Day with a reminder of how important it is to back up our data.

Data loss can occur when least expected, and it’s a shame that so many irreplaceable digital memories are lost. For businesses, it can be costly – the kind of costs that can close the doors!

So take the pledge today, and then get busy.

“I solemnly swear to back up my important documents and precious memories on March 31st.”

What is a backup?

A backup is a second (and sometimes third) copy of all your important files — for example, your family photos, home videos, documents and emails. It’s not something you do once a year and forget about; a good backup plan will be continuous and include multiple layers to not only recover your data but also include steps for data preservation.

The rule of thumb for backing up is

• 3 copies of anything you care about – Two isn’t enough if it’s important.
• 2 different formats – Example: Dropbox + DVDs or Hard Drive + Memory Stick or CD + Crash Plan, or more
• 1 off-site backup – If the house burns down, how will you get your memories back?

Experts advise that you store two copies of your files in external storage media. That can be a local drive on your computer, an external hard drive, you could print documents, burn a DVD, etc. You can backup important files or your entire computer. Another copy should be kept off-site. Many people use an “online drive” like Drop Box or Google Drive. “Cloud” backups are great for people who want to keep only their most important documents safe because there is usually only a certain amount of storage that’s free.

Don’t forget to back up the data on your mobile devices

Thirty seven percent of respondents we surveyed said they do not back up their data. Don’t wait until your device is lost or destroyed – today is the day to do your first backup!
