A
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 –
Powered by Symantec Backup Exec provides flexible,
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
