You can use the VSS COW Snapshot Scheduler wizard to add a snapshot schedule.
The scheduling capability automates the process of taking snapshots. At the scheduled time, the specified volumes are automatically snapshotted. Once configured and applied, the schedule is maintained by a scheduler service, VxSchedService.exe, that runs in the background. In a clustered server environment, ensure that the scheduler service is configured on each node with domain administrator privileges so that any node in the cluster can run the schedule after a failover.
To schedule a snapshot for a selected component
Name of this schedule |
Enter a unique name for the snapshot set schedule. This name identifies the snapshot schedule if you later want to view information about the snapshot status. A default name consists of the application name and a numbered suffix that increments with each schedule. |
Description of this schedule |
Optionally, enter a description to help you identify the schedule when you view information about the snapshot status. |
Start Time |
The time of the day to begin taking snapshots. |
End Time |
The time of day to end taking snapshots. If a snapshot is in progress it is completed but a new one is not started after the end time. |
Schedule takes effect on |
The date on which the specified schedule takes effect. The default is the current date. |
Restart task every |
The interval between snapshots, in minutes. For example, if the interval is 360 minutes and you schedule a snapshot start time of 12:00 P.M. and an end time of 7:00 P.M., the snapshot occurs twice. If no interval is specified the snapshot occurs once. |
Every |
Enable the Every option to have the snapshot schedule continue to occur. Otherwise the schedule applies only for one day. Specify the number of days before restarting the snapshot schedule. For example, 1 day would mean that the schedule takes effect daily, 2 days would mean every other day. |
Start On |
If you enable the Every option, specify the starting date. |
Pre Command |
Optionally, specify the full path of a command script to run before the scheduled snapshot occurs. |
Post Command |
Optionally, specify the full path of a command script to run after the snapshot is complete. |
Days of Week |
Select one or more days on one or more weeks of the month. You can click a button at the top of the column to select the entire column or a button to the left of a row to select the entire row. For example, clicking First schedules the snapshots to occur on the first occurrence of all the week days for the month. |
Days of Month |
Select one or more days of the month. You can also check the Last Day check box to schedule the snapshot for the last day of each month. |
Specific Dates |
Select one or more specific dates to include in or to exclude from the schedule. Excluding a date takes precedence over days scheduled on the other tabs. For example, if you schedule every Monday on the Days of Week tab, and you exclude Monday October 9 on the Specific Dates tab, the snapshots are not taken on October 9. |
If two schedules overlap for the same snapshot set, only one snapshot is taken. For example, if you select every Thursday plus the last day of the month, and the last day of the month occurs on Thursday, only one snapshot is taken on Thursday.
