Figure 1 effective security solution centralizes not only the backup, but also scheduling, tracking and auditing. LAN-free Linux on System z Level Data Protection LAN-FREE Linux on System z FileFile-Level Data Protection Virtual Granularity Recovery at the volume level is the fastest and most appropriate solution for disaster recovery. A full-volume restore can be done concurrently without interruption to an ongoing system and can support recovery of specific file data. A backup with file-level granularity, however, is a more appropriate solution to protect specific application data. An ideal backup solution will select only changed data when virtualizing, to synthetically create virtual full-volume backups and yet still support individual file recovery.

Leveraging the mainframe’s resilience and dataprotect ion, applicat ions can take advantage of its scalability, flexibility, efficiency and high performance to securely transfer backup data. z/OS Disk Tape Figure 2 Deduplication Savings De-duplication Savings z/OS Native Storage I/O LAN-Free Transfers Most Linux on System z data-protection solutions, even those that run under z/VM*, use TCP/IP to move backup data over the LAN. Such an approach is only suitable for small amounts of data. Even medium-sized databases and application files can create excessive network congestion and take a considerable amount of time to reach the protection of mainframe tape and disk. A LAN-free solution provides high-speed full-volume and file-level data transfer. For a model of LAN-Free Linux on System z file-level data protection, see Figure 1 (right). A limited number of transport methods are available for moving data from Linux on System z and enterprise open systems to a mainframe backup server: on network across a physical Ratio to 1 Percentage Saved Percentage Stored ESCON TS1130 FICON T10000 GigE Native 3590 3490 Tape Data 10,15, 20x+ De-dupe Tape I/O Metadata De-duplication Deduplication Appliance Appliance 3 12 16 20 25 50 67 % 92 % 94 % 95 % 96 % 98 % 33 % 8 % 6 % 5 % 4 % 2 % ibmsystemsmag.com/mainframe JANUARY/FEBRUARY 2010
