Configuring Streams for Oracle Backup Copy Operations

By default, backup data is sent to media in two streams. This means that a database is sent to media during a backup in two parallel waves. This results in backup taking about half the time to complete as it otherwise would if only one stream is used.

You can increase the number of streams used for backups for a particular subclient provided the number of streams does not exceed the maximum number configured in the subclient's storage policy. Increasing the number of streams for a subclient further reduces the amount of time a backup takes to complete. For example, increasing the number of streams from 2 to 3 enhances backup time from one-half that of a single stream to one-third.

Keep in mind that the same number of streams used for performing a backup will be needed to restore the data.
