I am trying to migrate my 8.2 Linux server to a new 9.0 Linux server. However, when I run the backup CLI, the whole server slows to a crawl, and eventually m clients call up saying their email client says the server is down. When I check load - I see it over 15. Is there a way to run the backup process without it monopolizing ALL of my system resources????? I can;t have my server effectively "down" while the backup is running!!! Any help would be greatly appreciated.
