SBT stands for Serial Backup Tape. Configuring Parallel Channels for Disk and SBT Devices The number of channels available for a device type when you run a command determines whether RMAN reads or writes in parallel. As a rule, the number of channels used in executing a command should match the number of devices accessed. For tape backups, allocate one channel for each tape drive.
