Home -> Community -> Mailing Lists -> Oracle-L -> RE: Compressing Rman Disk Backups
Did you consider looking for compressed file systems? I don't know if there is any for UNIX but my guess would be why not :)
Probably the compression would be on the file system block level to allow concurrency.
May be there is an option during the create and the mount of the file system that allows it to be compressed without buying other products.

Waleed

Subject: Compressing Rman Disk Backups
All,
I am attempting to perform Rman disk backups on a data warehouse. While the disk backup runs fine, the size of the output files are, of course, huge. What I would like to do is to pipe the output of the Rman backup while it is running to something like Gzip so that the file gets created compressed. My other option is to break the backup into a tablespace by tablespace multi-Rman run process and gzip or compress the files in between each step.
Anybody found a way to do this?
thanks
PS - Oracle 9.2.0.3 on Sun Unix.
