Tape Data Recovery and Backup Series *New*
The recent well-publicized backup tape losses at the likes of Bank of America and Ameritrade appear to be pushing some storage end users to consider alternative technologies such as virtual tape and online backup solutions.
Unfortunately, DDS hasn't really done much in terms of growth since the DDS-4 series, and
I haven't heard if there will be anything else from that direction, so I would likely steer clear
of that avenue. DLT has the potential (with compression) of storing up to 80 GB of data on a
single tape, SDLT (Super-DLT) now has the compressed capacity of up to 600GB, and LTO-
3 comes in at an impressive compressed capacity of 800 GB.
Tape backup is still the most frequently used
backup method for business users because of its
cost-effectiveness per megabyte of data, despite
the increasing popularity of recordable CDs and
DVDs. However, just like any technology, tape
drives, backup tapes and tape backup software
A little more than a year ago, a customer told me his company was going to write tapes remotely over an OC-3 connection. The tape drive being used was the StorageTek T9940B, which has a native transfer rate of 30 MB/sec and can support up to about a 68 MB/sec transfer rate with compression.
Answers to frequently asked questions about tape drive, tape failures and tape recovery services by expert Doug Owens.
Over the last few months, the issue of long-term tape archiving has come up in my work several times...
For more than 50 years, tape backup has been a cost-effective and reliable method for protecting organizations from data loss. There are several pluses to using tape, including the fact that it is able to work with all major applications and environments...
One of the big mistakes is not making sure the backup software has permission rights and
security privileges to access the servers and/or files that are to be backed up.
Data Recovery, RAID System and Related Backup Articles
Information has become a commodity in today's world, and protecting that information from being lost is mission critical.
RAID (Redundant Array of Independent Disks) is an acronym first used in a 1988 paper by Berkeley researchers Patterson, Gibson and Katz. It described array configuration and applications for multiple inexpensive hard disks, providing fault tolerance (redundancy) and improved access rates.
A description and analysis of common RAID types and their functions. If used correctly, disk drive arrays may provide several advantages over the single drive: higher reliability and higher data transfer rate.
An analysis of different RAID systems, configurations and their strengths and weaknesses.
There are two main purposes to RAID - a method of storing the same data in different areas (which is where the word "Redundant" comes in), and a way to speed up and stabilize your computer's performance.

For more than 50 years, tape backup has been a cost-effective and reliable method for protecting organizations from data loss. There are several pluses to using tape, including the fact that it is able to work with all major applications and environments. But a tape backup's effectiveness is only as good as the comprehensive business continuity plan that it is a part of.
Network security usually is thought of in terms of securing your network against threats that originate from the Internet. Attacks that come from the Internet are common and relatively easy.
RAID (redundant array of independent disks; originally redundant array of inexpensive disks) is a way of storing the same data in different places (thus, redundantly) on multiple hard disks.
RAID stands for Redundant Arrays of Independent Disks. In practical terms (to our business customers) RAID refers to the level of reliability built into a Server in terms of protecting data should one or more hard disks fail.
Keith Dunlap had never even heard of Cool-search.net. But one day last December, as he opened the browser on his home PC, the site filled his display. The browser's Internet Options window showed his home page had been changed to the arcane address t.rack.cc/hp.php.
Unfortunately, there might not be a straightforward answer to this pretty straightforward question. I could spend a fair bit of time praising the merits of each product, comparing architectures, features and performance. In the end, I would have produced a competitive advantage glossy similar to what most vendors already have.
With the migration of RAID, from RAID 0 to RAID 1 and through other variations to RAID 5, Midwest Data Recovery, located in the Chicago area, offers sophisticated RAID 5 data recovery services.
RAID (redundant array of independent disks) is the primary storage device of a SAN (storage area network). See how this $27 million integrator uses RAID controllers or SANEs (SAN enablers) to make sure mass storage solutions continue its 55% sales growth rate.
No matter how hard we try to avoid it, data disasters can and often do happen. This presentation will walk you through the data recovery process.
Backing up essential business data is kind of like getting enough exercise or eating the right foods - more effort seems to go into talking about it than doing it.
Many small business owners procrastinate unpleasant tasks, such as disaster recovery planning, in favor of more immediate day-to-day challenges. After all, who really wants to consider the outcome of unlikely catastrophes such as a flood, fire, hurricane, or tornado.....
Eventually you'll have to get a new computer. Don't
worry, it happens to all of us ;-) At some point your
old one will wear out, the hard drive will crash or be
erased, or something will happen where you need to
move old data to another machine. There are not many
guarantees in life, but I can guarantee this: if you
use your computer long enough, eventually you'll lose
some data, or have to move it from one computer to
A vital part of any security scheme is backup. No matter how tight your
security is, you always have the chance that a virus or hacker or even your
5 year old kid is going to slip through your defenses and damage your system
and your vital data files. If you don't back up your data regularly you will
be out of luck. And anyone who has been there knows how horrible it is to
realize that your computer is destroyed and there is no way to get the files
If you use a computer, regardless of whether or not it is connected
to the internet, you are in danger. You've spent some money on a nice
system and it's proven to be very valuable. You've got lots of
financial data (at least your checkbook), your graphics, scanned
photos and lord knows what else stored safely on your hard drive.
In today's world of online connections, hackers, information
nabbing, and other nefarious Internet deeds, many wonder what they
can do to protect themselves. This is especially true with those
who have an "always-on" or static IP connection to the Internet
(cable modem, DSL, etc.).
There is far more to antivirus software than just opening the box,
inserting the CD and installing software. To be properly protected
you may actually want to do a little more than that.
BIGGGG TROUBLE !!!! DO NOT OPEN "WTC Survivor"
It is a virus that will erase your whole "C" drive. It will come
to you in the form of an E-Mail from a familiar person. I repeat
a friend sent it to me, but called and warned me before I opened
it. He was not so lucky and now he can't even start his computer!
Forward this to everyone in your address book. I would rather
receive this 25 times than not at all. If you receive an email
called "WTC Survivor" do not open it. Delete it right away! This
virus removes all dynamic link libraries (.dll files) from your
When so many of us rely so much on our email to operate our
businesses or our personal lives, it is important to take
preventative measures to avoid the ultimate disaster of
Recovering from the accidental loss of valuable documents or data, whether
due to a disk failure or accidental deletion, can be accomplished quickly
and completely if regularly scheduled backups are done correctly. The
question to be answered is "what exactly needs to be backed up and when and
You want your computer to last. You've ordered the free preventive
maintenance report from www.hoytstation.com
, cleaned out
the mouse, kept out the dust... but that's all 'hardware' stuff.
What do you do to keep the software in good running order?
Minimizing the risk of disk failures, virus infections, or the accidental
loss of valuable documents or data can be accomplished quite easily by
following simple procedures in the areas of PC setup, routine disk
maintenance, virus updates and regularly scheduled backups. When done
correctly, the ability to recover quickly and fully from any of the
previously mentioned disasters is assured and your PC, as a consequence,
will perform optimally at all times.
Like all plans, there is an ultimate goal to achieve. The goal in a business continuity plan is simply that: to continue your business in the face of a disaster or a disruption. A business continuity plan is not just for a disaster. It's also for the smaller things in life, like your friendly neighborhood burglar who decides to borrow all of your computers or the small power interruption, which causes loss of data and downtime or the fire five floors below you, which causes a 5 hour building shutdown. These are a few of the many things, which do occur every day and do happen to companies like yours.
The risk analysis and business impact analysis have identified risks to key business functions. Also, the potential impacts and probabilities of these risks as well as the costs to prevent or mitigate damages and the time to recover will have been established. Evaluating and selecting strategies is based on using this knowledge. Strategy selection involves focusing on key risk areas and selecting a strategy for each one. The primary goals are to maintain business continuity in the face of a disruption or disaster, to recover key business functions quickly and to mitigate damages.
Essentially, the plan addresses the who, what, where, why and when of recovery. Goal number one is to reduce the risk profile of the business. Goal two is to be well prepared so the impact of any disruption is minimized. Overall, the objective of the plan is to effectively minimize the chances of disruption and, if there is a disruption, to quickly implement the recovery and get the business or organization working again.
RAID systems can be very complex in their structure and operation. In order to help you understand how RAID systems work we have included the following raid specific glossary. This glossary will help you to understand the terms and some of the procedures that are associated with our RAID recovery services.
Data storage has become an increasingly popular topic as information technology continues to redefine modern business practices. This glossary will help you to understand this growing segment of the I.T. industry and its affilition to data recovery services.
RAID (redundant array of independent disks; originally redundant array of inexpensive disks) is a way of storing the same data in different places (thus, redundantly) on multiple hard disks. By placing data on multiple disks, I/O operations can overlap in a balanced way, improving performance. Since multiple disks increases the mean time between failure (MTBF), storing data redundantly also increases fault-tolerance.
