I use osb and the following script to backup my db:
CONFIGURE RETENTION POLICY TO Redundancy 3;
CONFIGURE CONTROLFILE AUTOBACKUP ON;
allocate channel c1 device type sbt parms 'ENV=(OB_MEDIA_FAMILY=mftest)';
delete noprompt obsolete device type sbt;
backup database include current controlfile;
release channel c1;
I have read in oracle docs that when AUTOBACKUP oprion is ON, the 'include current controlfile' at the end of the backup command, causes rman to form one backup piece for both the database and controlfile.
But It always uses one volume for database backup and one volume for control file backup, although there is enough space on one volume for both of them. What can I do to backup both of them on one volume?
