s backup windows shrink and system avail-

ability requirements increase, IT organiza-

tions must find ways to protect and manage

their ever-growing data with limited staff and hard-

ware resources. Tape has been the traditional media

of choice for backup and recovery, but it comes with

a variety of disadvantages, including a lack of flexibility

and time-consuming data recovery. Although cost-

effective disk technology has been available for some

time, only recently has it become practical to imple-

ment disk-based backup as part of an overall data

protection strategy in enterprise IT environments.

To help meet the backup needs of organizations

of all sizes, Dell has worked with two leading backup

software companies, Symantec and CommVault, to

introduce two new backup-to-disk appliances: the Dell

PowerVault DL2000 – Powered by Symantec Backup

Exec and the Dell PowerVault DL2000 – Powered by

CommVault.

The new Dell PowerVault DL2000 –

cost-effective disk technology to support simple, man-

ageable data protection. Combining high-performance

Dell hardware and market-leading Symantec backup

and recovery software, this appliance helps accelerate

backup and recovery, enhance media reliability, lower

total cost of ownership, and minimize the need for IT

staff intervention and management.

TAPE- AND DISK-BASED BACKUP

Although tape has made significant improvements in

throughput and capacity, its sequential-access nature

typically makes it inflexible compared with disks.

Because the raw throughput of disk is typically faster

than tape, in most cases, backing up to and restoring

from disk is faster than using tape—disk drives can

begin transferring files instantly, whereas tape drives

require that the tape be loaded, accessed, and sequen-

tially written. Disk volumes, especially RAID volumes,

can have very fast read performance, rivaling the

throughput of even the newest tape drives. Disk snap-

shot technology, meanwhile, enables disk backups and

restores to be virtually instantaneous. Importantly,

these high levels of performance and efficiency enable

administrators to schedule frequent backups, helping

reduce the risk of data loss, while high levels of flexibil-

ity mean that, unlike tape, disks can support simultane-

ous backup, restore, and duplication operations.

Backing up multiple sources to a single tape drive

requires a technology called multiplexing, or inter-

leaving, which helps increase tape device efficiency
