Joni, You should be taking some how an online backup of the Notes nsf files and the Oracle databases. The nsf files won't compress at all, so you won't gain any reduction in used space on the disks/tapes where the backups end up. And with an olnine backup of Oracle, either directly to TSM or first to disk and then a file system backup to TSM, will contain only the used blocks in the Oracle data files. So no gain again with software compression on an Oracle server. Generally you will be using more resources on the client when the compression is done over there. The achieved ratio can be found in the summary of the backup session (for a file system backup). best regards, Kurt

Hello All! I am considering turning client compression on for our Lotus Notes Domino and Oracle servers. What should be looked at/considered before client compression is turned on? How do you monitor the impact of turning client compression on? Any ideas/suggestions are appreciated!
