This mezzanine backup-restore solution blueprint provides customers:
•
Faster single file recovery from inexpensive near online storage.
•
Decreased backup window by distributing file backups to near online storage and tape. Disk files
are then copied to tape for offline storage.
•
Increased data reliability by first capturing file backups to RAID-protected near online storage,
where failure does not mean data loss.
As required, offline or offsite backup files can be efficiently staged or copied to tape.
Solution design and design rules
An MSA1500 provides large-capacity, low-cost storage over a SAN. This storage is used by a data
protection application [HP OpenView Data Protector (Data Protector), VERITAS NetBackup (NBU),
VERITAS BackupExec (VBE), Legato NetWorker (LNW), or Computer Associates BrightStor ARCserve
Backup (CABA)] for mezzanine (near online/tiered) storage. In the example solution presented here,
an HP StorageWorks Enterprise Virtual Array (EVA) can back up data to tape resources through an
HP StorageWorks Network Storage Router (NSR) or to the MSA1500. Using zoning and Selective
Storage Presentation (SSP) in both the MSA1500 and the NSR, multiple hosts can be configured to
use the MSA1500 and NSR storage devices. While multiple hosts can share a single tape device
behind the NSR through the use of shared storage/SAN options in the application, each MSA1500
logical device [Logical Unit Number (LUN)] must be presented to one and only one host. A host may
have more than one LUN from the MSA1500.
Using the data protection application, a “virtual jukebox” (Data Protector), a “disk storage unit”
(NBU), a “backup folder” (VBE), a “File Device/Advanced File Device (LNW), or a “File System
Device” (AB) is created, pointing to the newly created/presented MSA1500 LUN. This allows the
MSA1500 to act as a backup target. Reading from the source disk array such as MSA1000, EVA, or
XP, data is packaged and backed up to the MSA1500 LUN using the logical backup device created
for the MSA1500 LUN within the application. Mezzanine storage provides faster single file recovery,
a reduced backup window, and increased reliability.
