ACRONIS BACKUP AND RECOVERY 10 ADVANCED SERVER - UPDATE 3 User Manual page 369

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.
Jan 1—Jan 7
Jan 8—Jan 14
Jan 15—Jan 21
Jan 22—Jan 28
Jan 29—Feb 4
Feb 5—Feb 11
Feb 12—Feb 18
Feb 19—Feb 25
Feb 26—Mar 4
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
