The verb form, referring to the process of doing so, is “back up”, whereas the noun and adjective form is “backup”. Backups can be used to recover data after its loss from data deletion or corruption, or to recover data from an earlier time.
Backup-as-a-Service (BaaS) – An approach to backing up data that involves purchasing backup and recovery services from an online data backup provider. Instead of performing backup with 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.
