Yes, we are going to start using RMAN down the road, but like the hardware, we probably won't be able to implement it before this surge of data hits. we have literally hundreds of databases where I work of all shapes and sizes. we like to keep the backup strategy the same, so going to RMAN is not so easy as it would be if we just had a few databases to work with.

So my questions remain -

Are concurrent hot backups and exports bad because of the fact that consistent exports make a lot of rollback, and when the rollback tablespace is getting hot-backed then there is contention? Is it unsafe or just not good practice?

thanks!
