automatically delete the oldest backup to free up space for the new one.

13.4.4. Full + incremental/differential backups with automatic
rotation
Because of Vista and Windows 7's housekeeping activities such as defragmenting and indexing that
usually run in the background, incremental and differential backups may be comparable in size with
full backups even if changes made by a user are few and far between. Taking this into account, the
optimum backup policy for users of Vista and Windows 7, as well as automatic disk defragmentation
programs such as Diskeeper may be making only full backups.

programs such as Diskeeper may be making only full backups.
With this in mind, let's consider a more complex backup strategy scenario requested by a real Acronis
True Image Home user. You want to schedule backups as follows: on the first day a full backup,
followed by 6 incremental (or differential) backups, than a new full backup. You want to keep 3 weeks
worth of backups but not more. At the beginning of the fourth week, once the full backup has been
created, you would like the program to automatically delete the full backup from the first week and
all 6 linked incremental backups. This is not possible to implement with one backup task, but three
backup tasks will provide the desired result.

Suppose you plan to make backups every night at 10:00 PM.
a) When you come to the Scheduling step while configuring the first backup task, select the Weekly
option, set "Run the task every 3 weeks", then select all seven days of week and set 10:00 PM as the
start time. Leave the current date as the "Start date".

c) Create the second backup task with the same settings as the first one. To do this, right-click on the
just created task on the Tasks and Log screen and choose Clone in the pop-up menu. Rename the
cloned task as you wish and then choose Edit on the toolbar or in the pop-up menu.

When creating the second task, make sure that the target archive name differs from the archive name assigned
in the first task, because if the names are identical the backups created by the second task will overwrite those
created by the first one.
