   Alternatively, you can also click Copy To and enter the year to which you want the custom months to be copied. Click OK and then click Apply.

   Note

   If there are some years with no custom month definitions in between the currently displayed year and the year specified in the Enter year to copy to window, the last defined year’s custom month definitions will be applied to those years without definitions. For example; the last defined year is 2007, but the currently displayed year is 2006. If 2010 is entered in the Enter year to copy to window, the 2007 custom month definitions will be copied to years 2008 - 2009, while the 2006 custom month definitions will be copied to year 2010.

2. Click OK twice.

#### Associating a Custom Calendar to a Storage Policy Copy

Associating a custom calendar to a storage policy copy changes the time intervals by which data is copied to and aged from this copy. Selective storage policy copies associated with custom calendars will have data copied during auxiliary copy operations either monthly, quarterly, half yearly, or yearly based on the days defined in the calendar.

If a storage policy copy is re-associated with a different calendar, the auxiliary copy operation re-calculates the dates in which data is copied based on the time definitions set in the custom calendar.

Use the following steps to associate a custom calendar to a storage policy copy:

1. Ensure that you have created a custom calendar using the Custom Calendars option in the Control Panel.

2. From the CommCell Browser, navigate to Policies | Storage Policies | <Storage_Policy>.

3. Right-click the <Storage Policy Copy> and click Properties.

4. Select a custom calendar name from the Calendar for Selective Copy and Extended Retention list.

5. Click OK.

#### Associating a Custom Calendar to a Job Schedule

Custom calendars can be used to create monthly and yearly schedules. For example:

- A monthly schedule for a custom calendar that defines months that are 32 days long runs every 32 days, starting on the starting day of the month as defined in the custom calendar.

- A yearly schedule runs based on the yearly number of days defined in the custom calendar.

The following sections describe how to create schedules using a custom calendar.
