To configure automatic checkpoints and to specify the checkpoint retention period, you edit settings in the CMS machine policy. Browse to the Checkpoints policy folder:
Defaults to 1140 (19 hours or 7.00 pm). This setting specifies when checkpoints are generated, or how often they are generated.
This setting is dependent on the Checkpoint Frequency setting (see below). If the Checkpoint Frequency setting is:
Set to zero, the Checkpoint Time setting specifies the number of minutes between each generated checkpoint. If the Checkpoint Time setting is also set to zero, scheduled checkpoints are disabled.
Set to one or more days, the Checkpoint Time setting specifies the number of minutes past midnight when each checkpoint is generated.
Note: If a new checkpoint is scheduled but there have been no infrastructure changes since the last checkpoint, a new checkpoint is not generated.
Defaults to 1. This setting indicates how often (in days) checkpoints are generated.
If the Checkpoint Frequency is zero, then scheduled checkpoints are either disabled or generated more frequently than one a day; this depends on the Checkpoint Time setting.
Defaults to zero. This setting specifies the number of infrastructure updates that trigger a new checkpoint. If this setting is zero, the update count threshold is disabled and checkpoints are not generated.
What is a suitable value for this setting? Unfortunately, we cannot give precise guidelines. A simple policy update, perhaps affecting a dozen trigger settings, may only comprise two infrastructure updates (to the policy and blob database tables). Conversely, a major restructuring of a typical user hierarchy, with its attendant impact on policy tables, the group hierarchy, e-mail address tables and so on, can easily comprise tens of thousands of infrastructure updates. We recommend that you leave this threshold set to zero and only change this under the guidance of CA technical staff.
Defaults to 60. This setting specifies how many days checkpoints and their acknowledgments are retained on the CMS. Set this value to zero to permanently retain checkpoints and acknowledgments.
To fully disable automatic checkpoints, set the following three policy settings to zero: Checkpoint Time, Checkpoint Frequency and Update Count Threshold.
