Archiving Rules

This section includes the following topics:

Setting Archiving Rules

Archiving rules are specific to each type of backup set and must be configured while creating or editing the backup set.

You can set the number of days that the backup versions are kept and set the number of versions that are kept. Archiving rules dictate how many versions of each file are kept. The maximum number of versions that can be kept is 99. The maximum length of time a version can be kept is Forever.

The more versions you keep, the higher the storage usage.

If changed, the Archiving Rule applies to the data you back up when the next backup runs. Previous backup sets are not affected.

How Archiving Rules Work

Note: Archiving rules for Files and Folders is used as an example for this section.

The archiving rules for Files and Folders can be selectively applied to particular files and folders. The This rule applies to field accepts wildcard filters using commas.

The default is to keep no fewer than 10 versions for at least 30 days.

Advanced archiving rules can be set based on the following parameters:

  • Days

  • Months
  • Years
  • Forever
Daily

A daily revision is the latest revision from a calendar day, or the closest to 23:59:59 time of day.

Weekly

A weekly revision can be set on any day of the week. The default value for weekly revisions is Sunday to follow the ISO date standard. If no revision exists on Sunday, a search for the closest day after Saturday is performed.

Monthly

A monthly revision is determined by the latest month (or closest to it). During monthly intervals the last Sunday from a month back up is kept, instead of the last day.

Yearly

The latest revision for that year is kept, or the closest to it. The revision day always starts on a Sunday.
