After you identify the data sources that you need to protect and determine your recovery goals, your next step is to analyze the information that you gathered so that you can organize the data sources into protection groups.
A protection group is a collection of data sources that share the same protection configuration. The protection configuration consists of the protection group name, and settings for disk allocations, replica creation method, and on-the-wire compression.
To plan a protection group, you must make the following decisions:
- Which data sources will belong to the
- Which protection method (disk-based,
tape-based, or both) will you use for the protection group?
- What are your recovery goals for the members
of the protection group?
- How much storage space will be needed to
protect the selected data?
- Which tape and library should be used?
- What method will you use to create the
replica for the members of the protection group?
The topics in this section provide guidelines for making the decisions involved in creating a protection group.
