| Selecting a Backup Solution
for Your Critical Information
A recent study conducted by Insight Express showed that 30% of IT
managers estimated that their companies lose at least $10,000 in revenue
and productivity after a server failure. For 85% of the respondents,
recovering from a server failure takes two or more hours.
The same survey, however, found that many
businesses lack backup plans or recovery measures. Thirty-five percent of
those surveyed don't back up on a regular basis. Insight Express also
found that 54% don't see the need to back up their entire systems more
than once a month.
And here's something else to consider: Gartner
Research has stated that two out of five enterprises that experienced a
disaster went out of business in five years.
For today's small businesses, it is no
exaggeration to say that information is the engine of their business.
Think about it. Everything about your company - product development,
sales, finances, human resources, everything - exists in and is managed
through your information system. Information technology isn't just an
administrative marvel, either; it's the repository and means of delivery
for the information that drives your business. In a very real sense, your
information is your company. How you protect it, manage it, and put it to
work is the key to business success.
Of course, all of these tasks have been greatly
complicated by the exponential growth in data volumes. According to a 2004
survey by Horison Information Strategies, a consulting firm that
researches the storage market, the amount of corporate data is increasing
at an average rate of 50 percent to 70 percent every year.
That's why, more than ever before, you need to
ensure that your network is adequately protected. It's also why you should
integrate your security technology and policies with an effective backup
and recovery plan. A multi-tiered approach should cover antivirus
programs, firewalls, content filtering, vulnerability management,
intrusion detection, and a regularly tested backup and recovery plan.
In the event of a system failure, such an
approach can have you up and operating again in no time.
Backup Procedures Maintaining the
integrity of the information on your system is essential. Hardware breaks
and people make mistakes, so it's imperative that you make frequent
backups of your system. How often should you back up? Should you perform a
full, incremental, or differential backup? The details below will help you
decide what type of backup best suits your business.
Full Backup - As the name suggests, a
full backup backs up all files on the system.
Incremental Backup - An incremental
back up only back ups the files modified since the last backup. This
type of backup is useful if you wish to have a log of file usage
activity. Incremental backup enables you to restore a specific day's
work without restoring any changes made since that point in time.
Differential Backup - Differential
backup is a cumulative backup of modifications made since the last full
backup. This type of backup enables you to restore all files changed
since the last full backup.
No Need to Choose In the past,
companies were often forced to choose between fast backups and quick
recovery. That's no longer the case. It is now possible to create backups
and restore to specific system recovery points quickly, ensuring that, in
the event of a crash, mission-critical systems are promptly brought back
online. Here's how the combination of the two solutions enables you to
maintain data availability while minimizing system downtime:
D2D2T Backups A multi-stage,
disk-to-disk-to-tape-based data protection solution offers significant
benefits over traditional backup media, such as tape drives. These
benefits include faster backup; improved media reliability; reduced
total cost of ownership (TCO); and reduced IT intervention and
management.
Recovery The latest recovery solutions
enable users to recover systems quickly and reliably with low-level
images of the entire logical disk structure, serialized and written to a
single file. Recovery solutions may be used for the following:
Bare Metal System Recovery. Depending
on the amount of data, a server with applications, settings, and data
can often be recovered in less time than it would take to reinstall the
operating system alone.
Change Management. Before a change is
applied, a system can be backed up while still online. You can also
prompt an up-to-the-minute incremental backup just before the change is
applied. If problems occur due to the new change, such as adding a
device or installing a patch, a recovery solution will enable a full
recovery back to the most recent incremental backup.
Introducing Continuous Backup In May,
Veritas (now a part of Symantec) introduced the Backup Exec "Panther"
beta, a solution that delivers true continuous data protection. The
Panther functionality captures granular changes in real time and ensures
information is continuously protected. In other words, whenever a change
is made, that change is captured and protected. Multiple versions of files
are captured and available for recovery or retrieval. True continuous data
protection means businesses no longer have to perform time-consuming full,
incremental, or differential backups.
Keep Up the Backup Below are some
additional things to keep in mind once you have a backup and recovery plan
in place:
- Scheduling - Know how long the network will
be down so you can set up convenient times to back up.
- Retention - Know how long data should be
retained - several months or for years?
- Review - After each backup job, review logs
and archives for errors.
- Library Maintenance - After spending the
time to back up your files and applications, make sure you clearly label
the media and note where it is stored.
- Rotation and Expiration - Depending on the
media used, you might be able to re-use the backup media. While
cost-effective, keep in mind that at some point the media will reach its
end-of-life and will need to be disposed.
- Disposal - Do not think throwing media in
the trash is enough. Physically destroy it so unintended parties cannot
access it.
- Verify Backups - Test your data restoration
so you can take corrective action if needed. Regularly scheduling test
recoveries ensures that backup procedures work properly when they're
needed.
Conclusion The ongoing explosive
growth in corporate data has resulted in a greater-than-ever demand on
small businesses to provide necessary data protection. A simplified and
automated process for backing up and recovering all data and system
information is key to keeping a business up, running, and growing.
