The following types of snapshot data set information are available:

  • General snapshot utilities data set statistics—general information about the performance of all snapshot utilities data sets. A selection option allows you to display the performance of a subset of snapshot utilities data sets that match the selection criteria.
  • Summary snapshot utilities data set statistics—comprehensive information about the performance of all snapshot utilities data sets with read and write activity
  • Individual snapshot utilities data set statistics—information about the performance of a specific snapshot utilities data set
  • Detail snapshot utilities data set statistics—detailed information about a specific snapshot utilities data set
Warning

Important

Snapshot Copy jobs that have been restarted accumulate statistics from the initial submission of the job, not from the restart point. Even if you restart a job several times, the statistics are not reset; they continue to accumulate.
