If you are adding a backup to the existing backup archive, the Full method will be unselectable.

You can set a backup policy for the backup task. Acronis True Image Home offers three types of

backup policies:

 create full backups only

 create full backups after a specified number of incremental backups

 create full backups after a specified number of differential backups

When the first backup on a schedule is executed, Acronis True Image Home always creates a full

backup.

If you choose (1) by selecting the Full method, you can also choose what to do with the previous full

backup when creating a new one. By default Acronis True Image Home overwrites the previous full

backup, but you can choose to keep it by unselecting the A new full backup overwrites the previous

one box.

If you choose (2) or (3) by selecting the Create a new full backup after box, the next backups will be

incremental (or differential) until the specified number of incremental (differential) backups is

reached. After the selected number of incremental or differential backups is made, the next time a

new full backup and a set of subsequent incremental (differential) backups will be created; this

process will then continue until you decide to change it.

When the Delete previous backup archive box is selected, creation of a new full backup in

accordance with the specified backup policy results in deletion of the complete previous backup

chain – the previous full backup and its subsequent incremental (or differential) backups regardless

of the overall limitations you set on the archive at the Automatic consolidation step.

If you decide to keep old backups (by not selecting the Delete previous backup archive box) and

creation of a new full backup results in violation(s) of the limits set for automatic consolidation, the

program will use the following algorithm:

1. if the actual number of backups exceeds the maximum number of backups; the program

automatically consolidates the old full backup with the oldest incremental (differential) one to

correct this quota violation;

2. if after correcting the number of backups limit violation other quota violations remain; the

program consolidates the oldest backup to correct the storage period of old backups limit

violation (if possible - otherwise it deletes the old full backup);

3. if after correcting the storage period of old backups limit violation the archive size limit violation

remains; the program consolidates the old full backup with the oldest incremental (differential)

one, then will repeat consolidation (if necessary and possible);

4. if after consolidating all the previous backups the archive size quota violation remains; the old

backup archive will be deleted in order to correct the violation;
