Access "Can Disk Speed Up Lethargic Backups?"
This article is part of the Vol. 2 No. 7 September 2003 issue of Is it time for SAN/NAS convergence?
Backup to tape is fraught with problems, not the least of which is that it's time-consuming. Storage managers already use cheap ATA disk to store secondary copies of data because it's more reliable and easier to restore from than tape. Can disk also help you reduce the amount of time it takes for you to do your backup in the first place? For Joel Larkin, network specialist with the Pension Benefits Guarantee Corp. (PBGC)--a government agency in Washington, DC that pays benefits to workers whose pension plans have closed--disk was the answer to decreasing the time it took to do a weekly full backup. Equipped with an ADIC Scalar 458 library with DLT 7000 drives (10MB/s compressed throughput or 36GB/hr), it was taking PBGC the entire weekend to backup approximately 3TB. With thousands of tapes to use up before being able to justify a drive upgrade, Larkin set out to find a way to "get our backup window down from all weekend to under a day." PBGC bought three Quantum DX30s, 3TB IDE arrays that emulate a P1000 tape library. Rated at about 80MB/s, (288GB/hr), PBGC... Access >>>

Where tape belongs
by David Braue
Ignore the industry babble about whether tape is dead or not: Tape is here to stay. But with the advantages of new low-cost disk systems--especially for fast restoration--tape's role in backup will likely change. The upshot: You'll likely be using your libraries differently.
