Efficient backup schedules can help maximize the number of backups retained in the fewest number of archival Snapshot copies. In addition to planning each individual schedule, it is important to carefully synchronize backup schedules directed to the same volume. Coordinating schedules from different clients or policies to the same volume can improve overall space savings.
This information applies only to FSE mode storage systems, because archival Snapshot copies are kept only for FSE mode backups. Ensure that the archival Snapshot copies option is set to on.
