Tanberg's RDX Breathes Life into Backup Hardware Market - Is RDX QuikStor the Answer? (
Page 2 of 2 )
Backup is one of those processes that many small
businesses still fail to take seriously. Some argue that it is too much of a
hassle, others say it is too expensive, while many more simply don’t have the
time to baby-sit a backup procedure.
Solution providers have turned to hosted solutions
to solve many of those problems, yet hosted storage fails to provide the real
advantages of a premises-based solution—namely speed, archiving and ownership
of the data. Until recently, tape or traditional hard drives were the only
options to the hosted methodology. Sure, some companies introduced removable
hard drives or other cartridge-based systems, yet those devices suffered from
high costs, fragility or other problems.
With all of that in mind, Tandberg asked a simple
question: What if you could combine all of the advantages of tape with all of
the advantages of a hard drive and eliminate the disadvantages of both in the
backup market? The company answered its own question with the RDX QuikStor—a
new segment of storage that features the backup capabilities of tape along with
the speed and low cost per gigabyte of hard disk-based storage.
The Tandberg RDX QuikStor drive is available in a
few different form factors and interfaces, including internal, external, USB
and eSata. We tested an External Kit, which included a USB
2.0-based drive and a 500GB cartridge, and retails for $799. Solution
providers will find that bare drives retail for as little as $199, while
cartridges range in price depending upon capacity. RDX cartridges are available
in capacities of 80GB, 160GB, 320GB and 500GB.
While $799 may sound like a lot of money, that
price point proves to be very inexpensive when compared with LTO or other tape
drive technologies. What’s more, QuikStor offers much more capacity than
traditional tape drives. Solution providers also need to consider how expensive
hosted storage solutions are based on gigabytes needed and the length of time.
Pre-buying a few gigabytes of hosted service for a multiyear period could prove
to be more expensive than the QuikStor solution.
Solution providers will appreciate the fact that
all RDX cartridges are interchangeable; in other words, any RDX drive will be
able to use any RDX cartridge, regardless of capacity. That offers a level of
economy and promises increased capacities in the future.
To save customers some money, solution providers
can go with a lower-capacity drive for the daily backups and then dedicate a
high-capacity drive for the monthly archives. That way, customers are only
buying the capacity that they need and can still preserve an upgrade path for
the future. The cartridges prove to be just as resilient as tape and can
survive knocks, drops and other shocks without damage. Tandberg states that the
drives have a service life of more than 10 years.
One of the most important factors to consider with
a hardware-based backup solution is speed—after all, for most businesses there
is a very narrow backup window, usually in the middle of the night, to back up
all of the data. Here, Tandberg has designed the drives to work as fast as 45MB
per minute (162GB per hour). During our testing, the drive did approach those
speeds, but on average we saw speeds of around 38MB per minute—a far cry better
than hosted storage and previously tested tape solutions.
Tandberg bundles in a backup program called RDX
File Keeper, which offers CDP (continuous data protection) and disaster
recovery protection. File Keeper uses byte-level CDP for all user data, protecting
data as it is written to disk. An imaging capability allows users to capture
complete hard drive images for disaster recovery purposes.
Even when the drive is not connected, RDX File
Keeper still operates. It “caches” backup data and then moves it over to the
RDX cartridge once connected. File Keeper’s CDP can also be defined to keep
multiple copies of data files based on time stamps to provide simple revision
tracking and control.
Realistically, File Keeper is a single desktop
user tool and is geared more toward the remote or mobile user. For server
protection or network disaster recovery applications, solution providers will
need to rely on companion products, such as Symantec’s Backup Exec or Acronis
True Image, or many of the other backup and DR products on the market.
Since the RDX system works with the OS as a
traditional external storage device, compatibility between the various backup
programs on the market should be excellent. Solution providers should note that
Tandberg does offer better integration with Symantec’s Backup Exec product by
providing the software drivers to leverage Backup Exec’s drag-and-copy features
found in Backup Exec QS.
Basic installation of the drive is simple; users
will only need to install the drivers and applications from the included CD and
then plug the drive into their USB port. It
is that simple. The included software is wizard-driven and extremely easy to
use. The external drive does require a separate power supply, which is included
and comes with multiple plugs to work with various electric grids around the
world.
With the RDX QuikStor, Tandberg Data has proven
that there is still some life in the backup hardware market and has created a
device that can back up small networks, branch offices and individual users at
a price that is very competitive to hosted solutions and much cheaper than
tape.
Hopefully, in the future, Tandberg will increase
the capacities and build rack-level appliances so that the impressive
technology and performance of the RDX system can find its way into the
enterprise.
