If you have ever forgotten to back something up on your personal computer, you know that will probably only ever happen to you once! If you run a business, it is simply unthinkable that this could happen and any data might be lost forever.
Backing up is essential. Hiring a backup service to do remote backup for a lot of businesses is a way to sort of set it and forget it. Because there is no manually backing up of the data there is no forgetting about it getting done; backups are automatic each day (or several times per day depending on how large the business).
If you are searching for a service to back up your data, make sure they encrypt the data that is being sent over the Internet to insure even more security. Moving unencrypted information including customer data and financial information increases the risk and likelihood that this information could be leaked. You do not want your business to ever have to think about this risk. Encryption will offer your business that layer of protection and peace of mind for both you and your customers.
