Snapvault snap sched 

Using snapvault snap we can take snapshot primary and secondary volume

In snapvault three types of snap schedule
sv_hourly
sv_daily
sv_weekly

Example: 

Pri > snapvault snap sched vol1 sv_hourly 10@10-16

This schedule takes every hour snapshot on vol1 and retain last 10 snapshot copies name called sv_hourly in the primary system.

Sec > snapvault snap sched –x vol1 sv_hourly 10@10-16

This schedule takes every hour snapshot on vol1 and retain last 10 snapshot copies name called sv_hourly in the Secondary system.

Using –x for incremental back up, that means secondary snapvault that compare the primary snapshot and if any modified data in the primary snapshot, it will copied the modified date to the secondary system.

NOTE: If you don’t use the -x option, the secondary does not contact the primary. This schedule take snapshot of vol1 without incremental
