Use this tab to determine for which instances the archive redo logs will be backed up or deleted and also the instance order for these tasks
Backup Archive Log
Specifies whether archived redo log files will be backed up. These logs can be applied to the database in order to recover it to a point-in-time. Keep in mind that when this option is selected, the Resync Catalog option on the Backup Arguments tab will automatically be selected by default. This option is not available when you select Offline Database.
Archive Delete
Specifies whether archived redo log files will be deleted once they are backed up. Any archived redo log files that do not match the format indicated by the LOG_ARCHIVE_FORMAT environment variable are not deleted. This option is available only when you select the Backup Archive Log option.
Disable Switch Current Log
When selected, log switching is disabled for the current redo log file during an archive log backup.
Archive Log Second Copy
Select to create a second copy of the offline redo log files which were already archived.
Use Traditional Backup for Logs
When you perform an IntelliSnap backup, select the Use Traditional Backup for Logs check box to have the software run a traditional backup of the logs after the IntelliSnap data backup is complete. Use this option when you want to reduce the total number of snapshots that are taken during the backup operation. When you use this option with the snap optimization feature (see Optimizing IntelliSnap Backups), the number of snapshots is reduced. The Use Traditional Backup for Logs check box is only available when you have selected the IntelliSnap check box on the IntelliSnapOperations tab.
