Backing up the database

In an Alfresco system, the ability to support hot backup is dependent on the hot backup capabilities of the database product Alfresco is configured to use.

Database hot backup requires a tool that can "snapshot" a consistent version of the Alfresco database (that is, it must capture a transactionally-consistent copy of all the tables in the Alfresco database). In addition, to avoid serious performance problems in the running Alfresco system while the backup is in progress, this "snapshot" operation should either operate without taking out locks in the Alfresco database or it should complete quickly (within seconds).

Backup capabilities vary widely between relational database products, and you should ensure that any backup procedures that are instituted are validated by a qualified, experienced database administrator before being put into a production environment.
