Thread: Necessity of Data Backups

If you're convinced about the necessity of data backups, you need to sit back and understand your requirements. The frequency of generation of data will determine your choice of software, as there are some upper limits to how frequently you can back up. Likewise with issues of retrieving older copies: some software allow you to store multiple versions of the same files, while others overwrite older versions and keep only the latest version in storage.

Data backup methods have evolved over the years. Until about a few years ago, most SoHos used the older and cheaper way of data backup¬optical media (CD / DVD). But though CDs and/or DVDs are still useful for one-time backups, they can be a pain in the neck when regular backups are needed. More user-friendly storage would be external USB hard drives. Many drives feature the "one-touch backup" option; they come with software that automatically backs up data at the press of a button.
