Set the time window in which backups for this policy can start. The type of window that you set on this screen depends on the following options you chose earlier in the wizard: instant recovery snapshots, full backup, or incremental backup.

• For the backups that go to a storage unit, start backups when resources are least occupied with business critical operations. For many sites, this time is late at night (Off hours). Although snapshot creation has little impact on the client, the moving of data to storage can affect client, server, and network performance.

• For instant recovery snapshots to disk, choose All day. Such snapshots require no data movement and when you create them throughout the day, they have better data protection. The more often snapshots are created, the more disk space they require.

  Note:

  A backup runs to completion even if the start window closes while the backup is running.
