World-class Application Backup and Recovery
A common expression among true information technology
experts is: “IT amateurs
backup; IT professionals recover.” The expression is popular because having a
solution that can just backup your applications and applications’ data is
ineffective. If you have a problem and you cannot quickly and easily recover
your applications or your application server, from your backups, is your backup
solution any good at all?
Every server based application should be properly backed up and easily
recoverable to prevent losses from data corruption; unforeseen disasters, such
as a hardware failure; and from any type of user error, such as accidental file
deletion. The expense and sheer complexity of implementing traditional general
purpose servers and third party tape backup solutions are common reasons why
several small and medium size businesses do not have an effective strategy for
backing up and recovering their applications and application servers.
Nitix Application Edition makes it easy for any small or medium size business
to backup its Linux-based server applications and, if need be, perform either an
application restoration or a complete
application server restoration .
Applications that run on servers are usually
applications that multiple users connect to simultaneously and/or applications
that store information in a database. Examples of server based applications
commonly found in small and medium size businesses include: accounting,
inventory tracking, client billing, and patient management systems. These
server-based applications tend to be extremely important to the normal operation
of the businesses that use them.
What would happen if an application running your server stops working
properly? Perhaps you had to patch the underlying operating system due to a
security issue; perhaps someone changed some configuration settings; or perhaps
the application stopped working for no apparent reason. Will your business be
down for a long time, or can you recover quickly? If your server-based
applications run on a general purpose server the answer is “it depends.” How
quickly can you figure out exactly what the problem is? Is it the application;
is it the operating system; is it a configuration issue; or is it something
else? Once you determine the root cause of the problem, do you know how to fix
it, and if so, how long will it take?
Choose to run your server-based applications on Nitix Virtual Server and
there is always a quick and easy way to get your applications working again.
With Nitix’s built-in idb backup feature, if any one
of your applications should stop working properly, you can restore the Nitix
Virtual Server environment to the way it was before the application issue
occurred. For example, if you suspect that an update you applied to an
application might have caused the application to stop working properly, click a
button and restore Nitix Virtual Server to the way it was before the update was
applied. It is that easy, because Nitix’s built-in idb
backup feature
can backup Nitix Virtual Server and all your applications as often as every
fifteen minutes.
In the event that a traditional general purpose server
needs to be completely recovered (perhaps from a hardware failure or from a
disaster, like a flood), typically the operating system must first be restored,
then patched to the latest version, then the backup software needs to be
restored and patched to the latest version, and then the application and
application data can be recovered, from the previous night’s tape backup.
Depending on the amount of data and the complexity of the application operating
environment, it is not uncommon for this type of restoration to take anywhere
from several hours to a couple of days to perform, which is especially
problematic if the server being restored is your only server. Once the
restoration of the server is complete, several hours of data might have been
lost. For example, if the overnight tape backup used to restore data from
completed its daily backup a 3:00AM, and a hardware failure occurred at 6:00PM
that same afternoon, an entire business day’s worth of data will have been lost.
With Nitix’s System-ER disaster recovery
technology and the appropriate replacement hardware, a Nitix-powered server can
be recovered from any type hardware failure into a functional state, in just
2-minutes. Once a Nitix server reaches a functional state, it is ready to
perform application services again. Next, Nitix’s
idb backup feature
will restore all the data that needs to be put onto the replacement server,
including the data required to restore the Nitix Virtual Server environment, so
that applications will run properly again. Nitix’s idb
backup feature
restores data a rate of approximately forty gigabytes per hour, which means that
a compete server recovery for a typical small and medium size business customer
will be finished in less than a couple of hours. Because Nitix’s
idb backup feature
performs backups as often as every fifteen minutes, no matter when a
hardware failure occurs, when the restoration of the server is complete, no more
than fifteen minutes of data will be lost.
