RMAN doesn't backup the entire database , but it does backup space that has EVER been used (as opposed to space that is currently used).
that is, perhaps at one stage more than 9Gb of space was in use and then records were deleted. One way around this is to resize the datafile (this can only be done if the free space is both continuous and at the start of the datafile. Have a look at Metalink Note:105208.1. HTH, Bruce Reardon -----Original Message----- Sent: Saturday, 5 October 2002 8:09 AM Since everyone's advocating RMAN here, I decided to start an RMAN backup for one of our development databases. And I had issues with disk space. Now, one of the tablespaces has been allocated 15 Gb of space, of which only 2.2 Gb has been used as per dba_extents. I started an RMAN backup directing this tablespace backup to be written to a file system with 9 Gb of free space. This backup filled up the file system and errored out. So, my question is, the first time you take a backup, does RMAN backup the entire datafile?
