Operation Manual

3) create full backups with specified number of differential backups

At first backup on a schedule, a full backup will be created. If the choice was (2) or (3), the

next backups will be incremental (or differential) until the specified number of incremental

(differential) backups is reached. Then again a full backup and a set of subsequent

incremental (differential) backups is created, then again a full backup and so on.

Using incremental backup mode, you can maximize the number of stored data “shots” given

the restricted storage space. However, archives with very long incremental “chains” are less

reliable since the corruption of any backup in a chain makes data recovery from the later

backups impossible.

Storing only full backups may be regarded as the most reliable and the most space-

consuming way.

Differential backups are almost as reliable as full ones since they do not depend on each

other but only on the initial full backup. No matter how many differential backups you

create, to recover data from each of them you will additionally use only the base full backup.
