Backing up and recovering the application serving environment
The product uses many operating system and application resources
that you should consider adding to your backup and recovery procedures.
About this task
WebSphere
Application Server resources can be saved while the product environment is
active. When backing up database data, you may have to shut down some or all
services if a snapshot cannot be obtained. This would occur if there are requests
which obtain locks or have open transactions against the database being saved.
In a distributed environment, you may need to consider how to get a consistent
backup across several systems. If the data on systems is not closely related
to data on other systems, you may be able to backup each system in isolation.
If you need a snapshot across systems simultaneously, you may need to stop
activity on all systems while the snapshot is taken.
How often you back
up resources depends largely on when or how often you expect them to change.
Procedure
- Back up your product environment configuration.
This
category covers the resources that define your WebSphere Application Server
operating environment. Once you have done initial setup, this information
should change very infrequently. You might backup this information only when
you change these settings, and not include these resources in regularly scheduled
backups.
- Back up your applications.
This category covers the
applications you run using WebSphere Application Server. You should back these
up the same way you back up other applications on your system. You could backup
these resources every time you add or change an application, or include these
resources in a regularly scheduled backup.
- Back up your application data.
This category covers
the data stores used by your WebSphere Application Server applications. Unless
your applications serve only static information, these resources are usually
quite dynamic. You should back these up the same way you back up other business
data on your system. These resources are suited for inclusion in a regularly
scheduled backup.
What to do next
If your applications are using other resources or services that are
external to the product, remember to include those in your backup plan as
well.
