Dianna,

I do this all the time.

My Unix Rman script runs Rman that puts the backups in a certain directory. I use the find command to compress all files that have not already been compressed. (find $BACKUP_DIR/* \! -name '*.gz' -print
-exec gzip {} \;)

These files are backed up by another tape process. I also use the find command to keep the directory clean (files older than a week are deleted).

I Ungzip the files for the weekly validate run or when we need Rman to run a restore/rollback. Easy enough to do.

Tom

Subject: Compressing RMAN backup pieces at O/S level

Per Metalink Note 247705.1
...
You can compress RMAN backup pieces at O/S level once they have been created
but keep in mind that these are not directly readable by RMAN. You will have to
manually uncompress these backup pieces before making them available to RMAN for
restore.
...

Does anyone do this or have any comments/thoughts? TIA.
Dianna G.
