User's Manual

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;
5. if the new full backup file size exceeds the archive size limit; the program will record a warning
into the log.
