Long-Term Protection on Tape
For long-term data protection, also known as tape archive, you can select a retention range
between 1 week and 99 years. DPM provides management support of your tape archives through
alerts and reports, and it uses the specified retention range to establish the expiration date for
each tape.
The frequency of backup is based on the specified retention range, as shown in the following list:
• When the retention range is 1–99 years, you can select backups to occur daily, weekly,
biweekly, monthly, quarterly, half-yearly, or yearly.
• When the retention range is 1–11 months, you can select backups to occur daily, weekly,
biweekly, or monthly.
• When the retention range is 1–4 weeks, you can select backups to occur daily or weekly.

Recovery Goals for Disk-Based Protection
Planning Protection Configurations
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 protection group?
• 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.
