Disk-based backup (original) (raw)

Disk-based backup refers to technology that allows one to back up large amounts of data to a disk storage unit. It is the technology which is often supplemented by tape drives for data archival or replication to another facility for disaster recovery. Additionally, backup-to-disk has several advantages over traditional tape backup for both technical and business reasons. With continued improvements in storage devices to provide faster access and higher storage capacity, a prime consideration for backup and restore operations, backup-to-disk will become more prominent in organizations.
