| 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.
