That'll tell you how much bandwidth you're using. If you're just about saturating your 100mb NIC, then BackupPC is not slowing you down.
Check 'iftop' when backing up a single host, and again when backing up a few hosts. Note that rsync takes some time to compile the file list, during which time it uses very little bandwidth. You might want to see how long it takes to compile the file list under various circumstances. Be sure to test it for both full and incremental backups (fulls take much longer). -Rob ******************************************************** The information transmitted is intended only for the person or entity to which it is addressed and may contain confidential and/or privileged material.
