Hi, One of my CentOS 4 server is a repository for backups for other machines. In this server, there is a 3ware RAID card and 2 HDD for the OS + data of this server. I also have 2 drawers (each containing one 200GB hdd), connected to a promise TX2000 card. One disk will remain in the server and one will be taken outside. What would be the best strategy for syncing the hdd when I swap them? Note: I don't want to do hot swap. No problem putting this server down once a week. It is a development server.
