Set schedules
Shadow Copy schedules control how frequently shadow copies of a volume are made. There
are a number of factors that can help determine the most effective shadow copy schedule for an
organization. These include the work habits and locations of the users. For example, if users do
not all live in the same time zone, or they work on different schedules, it is possible to adjust
the daily shadow-copy schedule to allow for these differences.
It is recommended that shadow copies be scheduled not more frequently than once per hour.
Scheduling shadow copies
When the Shadow Copies service is enabled on a volume, it automatically schedules shadow
copies to be made each weekday at 7 A.M. and 12 noon.
