Many companies would simply
stop working without access to their mainline business applications, so it is surprising to find that many companies' backup procedures fail to address best practices for contingency and business continuity planning. As a business owner you need to plan for contingencies such as IT failure, fire and flood, and there are a number of sensible backup procedures that you should consider implementing
to protect against IT failure and give yourself the best chance of keeping the wheels turning
when disaster strikes:
Data Backup
Every company needs a plan for data backup, and in fact most
companies do at least something. We often find however that these plans can be
very simple, and often just comprise taking a backup of the server to a backup
drive or tape.
Offsite Backup is a must!
Unless you have offsite backup of your company data, you are
not protected against real emergencies such as fire or flood, where both a
company’s main server and the backup drive can be destroyed. Given that loss of
your data through fire is effectively your worst nightmare, surely every
company should be backing up their business critical data (i.e. that which is
needed to get you up and running again) to cloud storage to protect against
this eventuality. Whilst many people still have legitimate concerns over data
security in the cloud, there are a number of suppliers that provide affordable
encrypted online backup which will protect your confidential data and ensure that you can recover your business
data swiftly in the event that disaster strikes.
Don’t Rely On Manual Methods
We also still find companies where offsite backup is a
manual process. While any offsite backup is better than none, do you really
want to run the risk that lightning strikes when the person who performs data
backup for you is on holiday? Given that there is little or no premium to be paid
for automated offsite backup software, we strongly advocate that you should
remove the element of chance and automate the entire process.
Don’t forget laptops and mobile devices
The great thing with laptops and tablets is that you can work
on the move and carry your work round with you wherever you go, but unless you
do something about it, that information is not going to be backed up anywhere
in the event that your laptop is stolen, lost or the hard disk fails. There are
some very neat solutions to address this issue now, some of which are built
into standard data backup solutions, and others which provide cloud backup /
synchronisation as part of a cloud storage service that allows you to share
information across desktop PC’s laptops and tablet devices. You will need to
take into consideration the way that your employees work in selecting the right
solution for your company, but backup for laptops and mobile devices should be
considered if you want to avoid the wringing of hands (not to mention data
recovery costs) when your laptop hard disk fails taking with it the business
plan that you have been working on for next week’s meeting with your bank
manager!
Plan For Resilience When Moving To The Cloud
Cloud computing adoption is now moving swiftly ahead. Apart
from email, many companies are starting to move business applications such as
Customer Relationship Management (CRM) and Enterprise Resource Planning (ERP) to
cloud based services. If industry experts are correct, we will all be buying
our business software on subscription from a cloud supplier within the next 5
years.
The benefits of cloud computing are clear. You gain access
to all of the software that you need to run your business without having to
invest in expensive servers, or the technical expertise to install and maintain
them. Furthermore social media services such as Facebook, Twitter and Google
Plus are becoming part of everyday marketing and customer service activity. Yet the more we become reliant on the Internet to run our
businesses, the more disruption we suffer when technology fails leaving us disconnected from our customers and business information.
Keeping The Internet Running
Fortunately, firewalls, routers
and the links that connect us to the Internet are fairly
reliable. Nonetheless, given the potential loss of productivity that businesses are likely to suffer in the event of the loss of
Internet service, it makes sense to make provision for backup.
Firewall Resilience
The majority of business class firewalls such as those
provided by SonicWall can be configured as a high availability pair such that a
secondary unit automatically takes over in the event of failure of the primary
firewall. The software and configuration of the secondary firewall needs to be
identical to the primary unit, but manufacturers provide concessionary pricing so
that the cost of firewall resilience is affordable.
Internet Link Resilience
Many firewalls will include the provision to automatically
switch over to a second line in the event that your primary Internet link
fails. Nonetheless, you need to be careful to ensure that your backup Internet
link enters your offices through a different route to your primary link. It
wouldn’t be the first time that a company’s primary link fails only to find out
that their backup Internet link enters the building using the same cable route
that has just been dug up by the gas board! To avoid this issue, there are two
options:
- If you can live with a reduced service for a few hours that
will provide you with limited browsing together with the ability to access
email, a 3G or 4G cellular connection
can be connected to the firewall for use when the primary link fails.
- If you need better performance, a 2 MB satellite link can
provide the backup Internet connection with only minimal degradation of
service.
The problem with building resilience into your IT systems is
working out where to stop. Should you install resilient hard disk configurations, mirrored servers, or do you simply outsource the problem of system resilience to a cloud provider? As a business owner, you will need to weigh the likelihood of a failure of a server, network component or internet link against the impact to your business and the cost of incorporating different levels of resilience, although we would be pleased to
advise anyone who needs some help in these areas.
The points raised above are simply
a starting point, but if they help you to formulate a Business Continuity
strategy that will help you to sleep a little easier, I will have done what I
set out to do.
