no, incrementals are more efficient on bandwidth. they do a less strenuous test to determine if a file has changed. at the expense of CPU power on both sides, you can compress the rsync traffic either with rsync -z or if you are using ssh then with ssh's compression. if you REALLY wanted to go

Hi, new to backuppc, I want to use to send my backups across the Internet (DSL) to an offsite server. Are there any known backuppc tweaks/settings that are proven to increase transfer performance over wan links? Specifically with using rsyncd or rsync as the transfer method. For example a prefe
