Backup and recovery for a distributed relational database

 

In a single system environment, backup and recovery take place locally. But in a distributed database, backup and recovery also affect remote locations.

The i5/OS® operating system allows individual tables, collections, or groups of collections to be backed up and recovered. Although backup and recovery can only be done locally, you might want to have less critical data on a system that does not have adequate backup support. Backup and recovery procedures must be consistent with data that might exist on more than one application server. Because you have more than one system in the network, you might want to save such data to a second system so that it is always available to the network in some form. Strategies such as these need to be planned and laid out specifically before a database is distributed across the network.
