Are Your Backups
The Best? It might be time to change from Tape to Hard
Drives
Most businesses back up their data to tapes. However, the
current trend is to move backups to hard drives instead. This new
method has become popular because of the introduction and low price
of external USB hard drives. Drive-to-Drive backup may be as simple
as copying the contents of one drive to another. However, companies
can still enjoy the same flexibility, reliability and automation
that backup software offers by using the software to back up to
drive instead of tape.
Backup to hard drives can offer
significantly reduced backup times to promote a more available
system. Even more important, it's a much more convenient way to
retrieve files from the backup. Loading a tape to search for a
single file to restore could take as long as an hour to setup the
restore job, load the tape, find the file and to restore it. By
comparison, that same restore operation could take a matter of
minutes with a drive-based backup because the seek times to find
that individual file are much faster on drive than on tape.
Moreover, when catastrophe strikes and a company needs to restore an
entire server, a drive restore is much quicker than a
tape.
Drive-To-Drive – Key Benefits
• Speed Hard drives are capable of backing up
data at sustained transfer rates of 50MB per second whereas the
fastest tape drives today perform at transfer rates of 20MB per
second using streaming. The big difference is that drives do not
need to be streamed, making it wonderful for typically slow backups
like incremental backups, transaction log backups and backups of
clients on slow networks. In addition since the access time is in
milliseconds for hard drives as compared to minutes in a tape drive,
restores are faster.
• Reliability Tape drives
require much more maintenance than hard drives. The headaches of
jammed tapes or cleaning tapes disappear. According to one of the
largest tape library manufacturers, tape drives mounted in a tape
library have an annual failure rate of 60%. Current hard drive
technology averages an annual failure rate of less than 0.8%. Also,
the shelf life of a hard drive is much longer than a tape drive.
Other Benefits of Disk-To-Disk
Fast
restoration can be crucial for mission critical data
Users are less likely to know for
sure whether a backup has successfully completed with tape
Drive prices have fallen
Cheaper backup strategy (media costs
reduced)
Independent Redundant units (better
than one expensive tape drive)
Hardware failure does not stop entire
backup plan
Less complicated recovery (in times
of stress)
From single drive internal and
external units to multi-drive rack and tower models, consider Highly
Reliable Systems. Capacity ranges from 80GB to an impressive 3.5
Terabytes total storage (uncompressed) in the 7 bay Rack-Mount model
using their 500GB HR media!
