If the SnapVault feature is scheduled to perform Snapshot management at the same time as default snap sched activity, then the Snapshot management operations scheduled using the snap sched command might fail with syslog messages, “Skipping creation of hourly snapshot,” and “Snapshot already exists.”
To avoid this condition, disable the conflicting times using snap sched, and use the snapvault snap sched command to configure equivalent schedules to create Snapshot copies.
