Backup and recovery of data files and databases
is an essential operation for any business system, particularly for
data and applications running in production environments. Create and
follow a plan for backing up and recovering data on all tiers of your IBM® WebSphere® Portal Express® deployment.
Backup and recovery includes the WebSphere Portal Express file
system and databases. Your backup and recovery plan needs to address
each deployment tier: complete system backup for catastrophic failures,
backup of middleware such as WebSphere Portal Express and IBM WebSphere Application Server, and backup of individual applications running on the
middleware. Backup and recovery can be performed on any or all of
these tiers, depending on the needs of your portal deployment.
When you create a backup and recovery plan, consider these general
questions:
- What procedure will you use to back up data?
- How often will you back up data?
- What are the trade-offs between online and offline backups?
- How does the scope of your portal deployment affect the backup
and recovery strategy? For example, the number of users and the volume
and importance of the data being stored and used in applications will
affect your decisions about backup and recovery practices.
- Will you use IBM Tivoli® Storage Manager or
other utility to back up the file system?
Attention: Backing up and recovering a WebSphere Portal Express installation
includes the WebSphere Application
Server runtime environment and all applications deployed
on WebSphere Portal Express.
However, if applications use remote information sources outside of
the WebSphere Portal Express databases
and the LDAP directory, you need to consider these remote sources
and develop backup and recovery procedures as part of your comprehensive
strategy.
