A survey of small businesses found that 41% had lost or accidentally deleted data from their computers. The top causes of data loss were hardware or software failures (31%), accidental deletions (17%), and computer viruses (9%). In response, many small businesses back up their data using external hard drives, CDs/DVDs, or flash drives. However, 31% find existing backup methods a hassle. To address this, Carbonite developed affordable cloud backup plans starting at $229 per year to provide small businesses predictable, unlimited backup storage.
