    Backuppc not backing up my linux client

    I have been struggling to get backuppc running and finally today figured out what I was doing wrong. Backuppc is running on my Ubuntu 10.04 server. I have it backing up my mac, but I can 't get it work on my Ubuntu 10.04 desktop. I followed the same steps I used in getting it to work in my mac, so I can't really see why there is a discrepancy. This is the error log I'm getting now:

    Code:
    full backup started for directory /
    Running: /usr/bin/ssh -q -x -l root 192.168.1.120 /usr/bin/rsync --server --sender --numeric-ids --perms --owner --group -D --links --hard-links --times --block-size=2048 --recursive --ignore-times . /
    Xfer PIDs are now 14404
    Read EOF: Connection reset by peer
    Tried again: got 0 bytes
    Done: 0 files, 0 bytes
    Got fatal error during xfer (Unable to read 4 bytes)
    Backup aborted (Unable to read 4 bytes)
    Not saving this as a partial backup since it has fewer files than the prior one (got 0 and 0 files versus 0)
    The dreaded 4 bytes error. I was getting that problem before on my mac, but from what I've managed to find, this error usually shows up when you don't have ssh keys set up properly. Once I got that figured out, it started working on my mac. I can confirm that that part is set up because when I execute the following as the backuppc user on the server:

    Code:
    ssh -l root mycomputername whoami
    The response I get is root, which means its working. And I'm not prompted with anything when I enter that line.

    That tells me the SSH part of the process is set up correctly. What could I be missing?

    Thanks for any help

    Re: Backuppc not backing up my linux client

    so I don't know if sharing my linux (linux mint 9 by the way) setup will help, but here is my:

    RsyncClientCmd: $sshPath -l root $host nice -n 19 sudo $rsyncPath

    also I notice you are trying to backup directory /, I haven't tried that. I first started with /home, and then others. I did have to exclude

    ./backuppc/.gvfs ......as it would hang on this.

    I also read somewhere in the docs that you can run backuppc manually and verbose to get much more feedback about what is causing trouble. I will review my notes and post it if I find it, goodluck.

    For this communication, I choose to call this command a "troubleshoot
    command" because it is the first suggestion to try from the backuppc
    wiki page. The "-v" of the 'BackupPC_dump" portion gives verbose output,
    so users can see what is happen and diagnose failure issues.

    When I ran this command, the only thing I remember having to do, in each
    case was, agree that the host was to be added to the 'known_host' file.
    If I understand ssh correctly, that would be the client being added to
    the server (backuppc server) 'known_host' file.



    Hopefully that can give you more hints as to what is going on....
