Home -> Community -> Mailing Lists -> Oracle-L -> Re: Compressing Rman Disk Backups
I suppose you could manage it with named pipes, and a gzip process sucking
on them. Might be kind of tricky with how rman does multiple backupsets.
I've always thought it would be incredibly useful to have a perl module that functioned as an MML for Rman. Just something that would open up the API so we could write perl backends that could:
compress backupsets
push backups over a network
save backupsets to the least full backup partition.
interface with third-party backup software that doesn't support Oracle
etc...
I don't know if that is feasible or not, but I'd love to see something like this.
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
