    Hey everybody, this is my first one over here, so upfront:
    great site so far and man I really spent a lot of hours already trying out the most of the how tos, not that they are so fdifficult but most of all they very interesting and many of them available;-).

    To the point:
    I tried to figure out http://www.howtoforge.org/dedicated_server_backup_restore_systemimager
    but it fails with

    Code:
    @ERROR: Unknown module 'scripts'
    rsync error: error starting client-server protocol (code 5) at main.c(1171)
    ERROR: rsync of the master script failed!
    
    So I took a look at the script itself and found this line

    Code:
    rsync $image_server::scripts/$image_name.master /tmp
    to be honest I have no clue what thi ":scripts" should be and why there is a ".master" behind the image variable

    One would think the command should be s.t. like
    "rsync -r $image_server:/var/lib/systemimager/images/$image_name /tmp"

    So I guess the error is somewhere there ..

    Would be amazing if some of you guys could gimme a hint ;-)
    thanks in advance

    Please post the output of
    Code:
    ls -la /var/lib/systemimager
    on the image server.

    ok this hints me to edit the ::scripts with my real directory which is /var/lib/scripts

    I edited your script and now i get this
    Code:
    --13:43:51--  http://www.falkotimme.com/howtos/dedicated_server_backup_restore_systemimager/functions
               => `functions'

    mv: cannot move `functions' to `/etc/init.d/functions': No such file or directory
    /tmp/my_image.master: line 13: /etc/init.d/functions: No such file or directory
    
    btw I also use a strato server but the rescue system does not seem to be busy box .. this maybe a problem right?

    ok next thing I now just made an mkdir /etc/init.d/ so your skript can work

    but next failure is this

    Code:
    
    --13:58:51--  http://www.falkotimme.com/howtos/dedicated_server_backup_restore_systemimager/functions

    Old partition table for /dev/sda:

    write_variables

    LFS based rescue system
    
    ok this is caused because my image originated from an sda install and the server only has a hda
    so I just changed the sda`s with hda`s

    but now I ended up here
    Code:
    : bad interpreter: No such file or directory
    
    I think this is caused by this
    Code:
    ::${IMAGENAME}/
    part in the my_image.master
    and I am sure it fails for the same reason like the script failed in the first place above where I replaced
    ::scripts with my real directory which is /var/lib/scripts

    but I dont know why this doesnt work out of the box ?
    what do the two colons mean?

    I guess you have edited the file on Windows and then transferred it back to your server? Make sure you save the file with Unix linebreaks, not Windows linebreaks.

    hmm ok so i started it all over again, I did edit the files in windoze, because the f.... up vi on the rescue system didnt let me to.


    but the root of all evil still seems to be the following notation
    Code:
    rsync $image_server::scripts/$image_name.master /tmp
    could you please explain to me why there are two colons right one after another?
    Code:
    ::
    maybe this is just damn easy but I ve never encountered such a notation I am just familiar with
    Code:
    rsync $image_server:/scripts/$image_name.master /tmp
    Is this some kind of shortened way for a path?

    And man, thanks so far for your quick replies and your kind help.
    It is great to have such support in ones learning process


    ADDED:
    I asked around a bit and looked at the rsync man pages and there I found that the
    Code:
    rsync HOST::SRC DEST 
    and that this requires a rsync daemon....

    so I guess for your script to work a rsync daemon must be running?

    Yes, you must have rsync on your rescue system.

    I found it ;-)

    on the the image server runs a xandros system and for whatever reason, the rsync manager included in systemimager-server was not startet...

    now everything works fine just right out of the box without anything needed to be edited
    JUST it ends with a few errors ;-:)

    I don't know where the df warnings come from, however, they are warnings, not errors.
    Have you tested if the image works afterwards?
