The method used follows loosely the grand-father/father/son method typically used in backup procedures. There are 3 rules to decide if a backup file will be kept :
|•||For how many days do you wish to keep backups.|
|•||After that period, for how many weeks do you wish to keep the backup of a given day of the week.|
|•||After that number of weeks, for how many months do you wish to keep either the first or the last backup of the month.|
Your company's network administrator probably already has a backup scheme in place, and I suggest you contact him/her to make the Q++Studio backup purging correspond to your company's guidelines.
