6.2.9.3 Simple scheme
With the simple backup scheme you just schedule when and how often to back up data and set the
retention rule. At the first time a full backup will be created. The next backups will be incremental.
To set up the simple backup scheme, specify the appropriate settings as follows.
Backup Set up the backup schedule - when and how often to back up the data.
To learn more about setting up the schedule, see the Scheduling (p. 162) section.
Retention rule With the simple scheme, only one retention rule (p. 39) is available. Set the retention
period for the backups.

At a glance
 Daily incremental, weekly differential, and monthly full backups
 Custom day for weekly and monthly backups

Description
Let us suppose that we want to set up a backup plan that will regularly produce a series of daily (D),
weekly (W), and monthly (M) backups. Here is a natural way to do this: the following table shows a
sample two-month period for such a plan.
