If you execute a job sequence with automatic restart, jobs that complete successfully record a checkpoint.

Should not all the activities in the sequence finish successfully, restarting the sequence will skip any checkpointed activities. An entry will be logged indicating that they are being skipped.

Some activities, however, must run irrespective of whether it's a full run or a restart run of the sequence - for example a routine activity or job activity that generates a unique run ID must execute every run. Using "do not checkpoint" is how you guarantee that this activity is executed every time the sequence is executed, not just on full runs.
