The channel is a disk and the backup files are all going to that same disk.=

CONFIGURE DEVICE TYPE DISK PARALLELISM 4; # default

CONFIGURE CHANNEL 1 DEVICE TYPE DISK FORMAT '/u01/backup/oracle= _sid/bu.d%d.t%t.s%s.p%p' MAXPIECESIZE 1 G;

Is this going to run faster or the fact of a single disk will slow it down?=
