I agree with the suggested ratio as a starting point. It's a very good idea to have multiple BackupPC servers. a) It spreads out the bisectional bandwidth of the backup process, since it's an 'embarrassingly parallelizable' problem. b) Each backup server can back up the configuration of the other backup servers, thus avoiding the chicken-and-egg problem of "how do you restore your backup server when it dies?" c) Important backup targets can be backed up on multiple backup servers, in case one of the backup servers happens to be dead when you want to restore a backup. d) It becomes easy to geographically distribute your backup servers (to different buildings, cities, or even continents), depending on bandwidth availability. -- Carl Soderstrom Systems Administrator Real-Time Enterprises www.real-time.com ------------------------------------------------------------------------------ Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.
