I'm using backuppc version 3.1.0-6ubuntu4 on Ubuntu 9.10. I'm using "fairly recent hardware" (my backup server uses an Intel Atom 330 CPU, a 1.6 GHz dual-core CPU), yet, this effects me. Here's some of the output of top during a backup:
28539 backuppc 20 0 202m 141m 1368 R 98 4.0 5:26.85 BackupPC_dump 25224 backuppc 20 0 49288 7632 2408 R 79 0.2 1:56.49 ssh Both cores are nearly fully utilized. This remains relatively constant. (On the machine being backed up, a 4 core 2.3 GHz AMD Athlon(tm) II X4 605e, sshd usings just 10%-15% of one of the cores.) I'd suggest fixing this. To minimize the amount that a backup interferes with other programs running on a client, I changed RsyncClientPath to `nice -n 20 /usr/bin/rsync'. Unfortunately, using the same trick for the server does not work: changing SshPath to `nice -n 20 /usr/bin/ssh' results in: Error: SshPath must be a valid executable path (using /usr/bin/nice in space of nice doesn't work either.) It should be relatively painless to prefix the commands that backuppc exec's with a nice. Please do this.
