So we all know that it's important to keep an up to date backup of anything that's essential to our businesses. Client information, listing photos/info, business expenses, not to mention priceless family photos. What do you all use to backup your data? External hard drive, online backup, or the old fashion burnt CD's/tape drives? I'm looking for a good online solution (to protect against hardware failure, as well as disasters such as fire & theft). Can anyone recommend one?
