Oh, I see, you have been having a conversation, but forgot to include any of that context for people to comment on. I'll take a random stab in the dark: 1) You are using rsync to backup remote hosts 2) You are looking at the speed shown by backuppc for the transfer 3) You are multiplying that speed by the amount of data you need to backup, across all your machines You have overlooked a number of factors: 1) Enable checksum caching, and complete at least 2 more full backups, then complete a third full backup and start looking at the times 2) You will almost certainly do some incremental backups in between the full backups 3) If you have 50 hosts, and each one takes 1 hour, will it take 50 hours to complete the backups? NO. You do 5 in parallel, it will take 10 hours. 4) If you take 1 hour for a full backup, an incremental will probably take 10 minutes (or less), and if you do one full backup every 7 days, then 42 machines will do incremental backups on any particular night (approximately). So, take a breath, if any of the above is wrong, then we are happy to discuss it, but you will have to provide some details. Whatever problem you have, someone else has almost certainly had the same problem and solved it, not to say there are not some very difficult issues, but they can be resolved if worked through.
