Description

  • SnapMirror lag is the difference between when a snapshot is created on the source system and the system time on the destination
  • Lag time can be higher than expected due to a failed transfer, long running transfer, a scheduling issue or if the last transferred snapshot is not the latest and an old snapshot is still in progress
  • Incorrect destination cluster time could also lead to an inaccurate SnapMirror lag
