Faster backup and single file restore than tape solutions Can offer data deduplicatation and replication Automation Emulate tape - can simplify imple mentation and minimize changes Lower TCO Offline data protection Automation (Library) Energy efficient Long shelf life Portable High capacity/small footprint WORM (LTO-3 & LTO-4) Combines the data access speed of disk for backup and data protection attributes of longer term data retention
â—?
â—?
â—?
â—?
Restrictions Most expensive High energy consumption Not portable to offsite Online (suffers from same risk exposure as primary storage) Requires maintenance Higher cost and energy consumption than tape Media not physically portable to offsite Appear more complex to use than tape Slower restore for single file
â—?
â—?
â—?
First tier backup from primary (D2D)
â—?
Second tier backup in cost disk or VTL First tier backup in cost conscious environments Active and deep archival Offsite for disaster recovery
â—?
â—? â—?
â—?
Need to set policies and procedures to manage migration of data form disk to tape
24/3/2553, 14:38
Suggested Application First tier backup from primary disk (D2D) Mission critical data
