Hello, One of the Backup best practices is to rotate your backups.
A common rotation scheme is Grandfather-Father-Son (GFS), which has been in use for quite some time and has proven to be effective. In the generic version of this scheme, full backups are done at two intervals. The first interval is monthly (grandfather). Weekly full backups are also performed (father) then for a predetermined number of weekly cycles (two or three cycles is generally sufficient) switched with grandfather back-up. Daily incremental backups can also be performed (son).
This feature can not be automatically setup in McAfee Data Backup. As some data is only consulted sporadically. The chance of over-writing an existing backup with corrupted data is big with a simple weekly backup sheme.
