Backup as a service (BaaS) is a way to back up data that by purchasing backup and recovery services from an online data backup provider like Xiologix. Instead of performing backup through a centralized, on-premises IT department, BaaS connects systems to a private, public or hybrid cloud managed by the outside provider. Backup as a service is easier to manage than other offsite services. Instead of worrying about rotating and managing tapes or hard disks at an offsite location, data storage administrators can offload maintenance and management to the provider.
