Overview - Informix Data Agent
The Informix Data Agent provides an unique, simplified, end-to-end backup and recovery solution for Informix system and user databases in your enterprise. In addition to a complete protection of the system databases that contain user database characteristics, database objects, it also provides more granular backup and recovery of your enterprise’s data, emergency boot files (ixbar), ONCONFIG files, and the logical log files.
You can perform a full or incremental backups of the entire database, individual dbspaces, or logical logs at any point of time.
You can backup both the system and user-defined databases. You can comprehensively backup all the databases in an instance or schedule backups for the individual databases.
In the event that a MediaAgent used for the backup or recovery operation fails, it is automatically resumed on alternate MediaAgents. In such cases, the backup or restore job restarts from the beginning of the job. This behavior is due to a restriction of the OnBar utility that the Commvault software interfaces with.
In the event, that a network goes down, the backup and recovery jobs are resumed on alternate data paths. Similarly, in the event of a device failure, the jobs are automatically switched to alternate disk and tape drives.
You can view and verify the status of backup and recovery operations from the Job Controller and the Event Viewer within the CommCell Console. You can also track the status of the jobs using Reports, which can be saved and distributed. Generate reports for different aspects of data management. Customize the reports to display only the required data and save them to a specific location in different formats. For example, you can create a backup job summary report to view the completed backup jobs.
You can schedule, generate and send the Reports via email without user intervention.
Deduplication identifies, and then eliminates the duplicate items in a data protection operation.
Deduplication at the data block level compares blocks of data against each other. If an object (file, database) contains blocks of data that are identical to each other, then block level deduplication eliminates storing the redundant data and reduces the size of the object in storage. This way dramatically reduces the backup data copies on both the disk and tapes.
The Informix Data Agent documentation uses the following terminology:
|The computer in which the Data Agent is installed and contains the data to be secured.|
|The Informix Server to be used for the backup and restore operations. Each instance can contain one or more of the databases that you want to back up.|
|The Informix database objects that you want to back up.|
