Delays in backup job transfer and completion
Sometimes you may see a Oracle backup job pause for an extended time during the data transfer. Also, the backup job may appear to hang after the transfer completes but before the job completes. The delay may be due to one of the following:
Oracle delays
Network issues
Storage unit delays
Oracle database server post-backup processing
