EHLO,
I have this small but annoying problem: it seems my backuppc setup with
rsync over ssh is copying every file every time and only determines on
the local server what has changed - instead of copying only the changed
files. Needless to explain this isn't very optimal or efficient. :)
I noticed this issue when I was adding 30 GB of static data to the
remote server. In the first night I saw a lot of extra traffic. But,
in the following nights I saw that same pattern again (a lot more
bandwith being used). As these additional 30 GB are static content, I
would expect all nights but the first to see limited amount of traffic.
Both servers are running Debian 4.0 Etch. I am running BackupPC version
2.1.2-6, with the OpenSSH client version 4.3p2-9etch2 on the server that
is doing the backup and OpenSSH server version 4.3p2-9etch2 and rsync
version 2.6.9-2etch2 on the remote server. The data is stored on local
ext3 partitions.
Relevant snippets of the configuration files:
| $Conf{RsyncArgs} = [
| '--numeric-ids',
| '--perms',
| '--owner',
| '--group',
| '--devices',
| '--links',
| '--times',
| '--block-size=2048',
| '--recursive',
| ];
And:
| $Conf{RsyncClientCmd} = '$sshPath -4 -q -l backuppc $host nice -n 19
/usr/bin/sudo $rsyncPath $argList+';
What is it that I am overseeing?
