I've seen behavior like this on AIX, but it shrinks the file back down after the backup is complete. I've not seen this on NT that I recall, I'll have to test it.

Talking to the sysadmin I learned an interesting fact about RMAN and disk allocation. When I use the "set limit channel d1 kbytes=3000000;" to limit the size of the file created during the backup it creates a file on the backup disk and allocates the space for the 3000000 kbytes. It actually uses less than that as it backs up the datafiles. My guess is that it will only place contigous datafiles in the space allocated and not use the rest if it involves splitting a datafile during backup. If I used a smaller kbyte limit there could be more wasteing of space occuring. Is this the same on other OS's? I do not have another system OS to play with.
