Replication / What if scenario ? • • Q. If a Replication update does not complete and a new update is scheduled, is the new update just skipped or does it start right after the previous update completes? A. If a Replication update is still in progress when the next update is scheduled to begin, it marks the relationship to run again and will start the new update at the top of the next minute. For example, if you have an hourly update and the 1 a. m. transfer goes to 2: 30 a. m. , the 2 a. m. scheduled update marks the update as desired and begins the new update at 2: 31 a. m. If that update finishes before 3 a. m. , updates will be back on schedule. If that update finishes at 3: 05 a. m. , the next update will begin at 3: 06 a. m. As another example, if you have an hourly update a 1 a. m. that finishes at 3: 30 a. m. , the replication engine marks the relationship for running again at 2 a. m. and 3 a. m. At 3: 31 a. m. , the replication engine begins the next update. If that update finishes before 4 a. m. , the next transfer will begin at 4 a. m. Note: If a scheduled update is reached when a previous update is running, the replication engine marks, not queues, the relationship to do another update. Only one mark is seen, regardless of how many times the relationship is marked to go again. 13 Net. App Confidential

Replication / What if scenario ? • Q. Under what conditions can or cannot a replication transfer be restarted from a checkpoint and what is required to ensure that an interrupted transfer with a checkpoint can restart from the checkpoint? • A. The replication engine saves restart checkpoints during a transfer so that in case of transient errors like temporary network outages, it can resume the transfer rather than resend the data it has already transferred. Replication transfers take a new checkpoint every five minutes. The replication engine retries an interrupted transfer from the checkpoint until the next update transfer is scheduled. The next time a transfer is scheduled to begin, abandon the interrupted transfer and start the update from the last base snapshot. 14 Net. App Confidential
