I just finished one of these.

I did not back up data to the original server, tsm-a in your case.
I set all backups to occur to tsm-b.

Just did not run expiration on tsm-serverb until the export was finished.

If things got tight, I suspended the export to free up resources, then resumed 
as necessary.

It was very slow.  About two terrabyte in something around 96 hours.
Won't do that again unless forced.

Hope this  helps.

Subject: [ADSM-L] Another export question

Question - this may be obvious but I want to make absolutely sure





Does exporting data at the same time it is backing up cause a issue?



Example: I am exporting a client node from TSM SERVER A to TSM SERVER  B and 
it's a large export and it has run more than a day. Can I allow the backups to 
run (on the TSM Server A original server) while the export is still going on 
without causing a problem? It will eventually export any new data over to the 
new TSM SERVER correct?







Note: I created the node on the TSM SERVER B but it's going to backup on there 
yet of course



Thanks
