For years, tape storage systems have played a key role in efforts to store data for backup and retrieval, archiving, and contingency planning purposes. More recently, tape has been called on to help preserve and safeguard data to meet data retention laws and regulations. The challenge is how to manage, retain, and safeguard the data volumes being generated today. To put the data explosion issue into perspective with respect to its impact on tape, consider that even in last year’s tough economic times shipped disk storage capacity grew at a remarkable rate. All of the data being placed on that new disk capacity needs to be backed up, and much of it must also be retained for long periods of time. New tape technology provides a solution. With a capacity to store 3 TB of data per cartridge, recently introduced Linear Tape-Open (LTO)-5 tapes offer twice the storage capacity of LTO-4 and about four times the capacity of LTO-3 systems.
