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.

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.

Daily backups run every workday except Friday, which is left for weekly and monthly backups.
Monthly backups run every fourth Friday, and weekly backups run on all other Fridays.
Monthly ("Grandfather") backups are full;
Weekly ("Father") backups are differential;
Daily ("Son") backups are incremental.
Parameters
You can set up the following parameters of a Grandfather-Father-Son (GFS) scheme.
Start backup at: Specifies when to start a backup. The default value is 12:00 PM.
Back up on: Specifies the days on which to perform a backup. The default value is Workdays.
Weekly/Monthly: Specifies which of the days selected in the Back up on field you want to reserve
for weekly and monthly backups. A monthly backup will be performed every
fourth such day. The default value is Friday.
