interesting , we are actually thinking about using this. what are your thoughts . how are restores performed if data is moved to tape.

In short, we backup up to disk, then based on age of the files, 2 days, 5 days, 7days, the savesets are moved to tape. Works great.

I think a big part of the problem is that during backup, rman can shovel the files into Networker in parallel, but when it is time to restore the files, the parallelism (or most of it) goes away. We have started keeping a copy of the backup on disk as well as on tape. We have just started this for the same reason you have experienced, so we are still experimenting. Our current strategy -- subject to change if somebody comes along with something better -- is to backup to disk; then run a script that uses mminfo to see what is on disk that isn't on tape; then use the save command to send the new files to tape; then delete yesterday's backup from disk. In our case, we have about 1.8 Tb allocated for this. So yeah, we're talking about a wee bit of disk space here. ---------------------------------------------------------------- Please see the official ORACLE-L FAQ: http://www.orafaq.com ---------------------------------------------------------------- To unsubscribe send email to: oracle-l-request@xxxxxxxxxxxxx put 'unsubscribe' in the subject line. -- Archives are at //www.freelists.org/archives/oracle-l/ FAQ is at //www.freelists.org/help/fom-serve/cache/1.html ----------------------------------------------------------------- ---------------------------------------------------------------- Please see the official ORACLE-L FAQ: http://www.orafaq.com ---------------------------------------------------------------- To unsubscribe send email to: oracle-l-request@xxxxxxxxxxxxx put 'unsubscribe' in the subject line. -- Archives are at //www.freelists.org/archives/oracle-l/ FAQ is at //www.freelists.org/help/fom-serve/cache/1.html -----------------------------------------------------------------
