Re: Backing up via NFS.

[Dan L. Ostrom]

All,
        Along these lines, I too have tried doing an NFS backup using
Amanda, without much luck.
        
        The *client* machine, is an SANS, so installing client daemons
on it is out of the question.

        Doing an amcheck pointing to the nfs mount point in the conf file
would fail with the typical *dis. offline* error message.

        There was this link on the WEB about getting this to work that a
co-worker pointed me to:

http://www.karakas-online.de/myAMANDA/test.html

        So, I then changed my conf file to point to the nfs mount point and
specified using tar to do this. I then modified the
client-src/sendbackup-gnutar.c and commented out the --one-file-system line,
recomplied and installed amanda.

        For testing purposes, I told it to backup 1 directory, less than 2k.

        I then did the command line check (shown in the URl) and it came back
with a size parameter (this supposedly is what amdump looks for, more
specifically, the sendsize module).

        I was then able to do an amcheck, and it succeeded. Doing an amdump still
fails however. Looking into the log file (sendsize.-----.debug) it indicated that
amdump is not receiving the size information (presumably from sendsize module)
that it needs to complete the tar.
        
        It is bewildering that amcheck works, but amdump would fail, but then
amanda was written to have clients out there, so this is a little beyond it's
scope. I am not a C programmer, but I am going to continue to *hack* at this
to try and get it to work.

        If anyone else out there has already solved this problem, please by
all means send the fix. I really don't need to re-invent the wheel

        Thanks.

Hey, Paul: yah; I'm already using tar instead of dump.

Yeah.  It's actually the libraries, etc., that're giving me the most grief.  Guess it's time to hunker down and just get 'em all.

True 'nuff, but I wouldn't know where to begin.  Think I'll take the "compile, darn you" approach.  Assuming I get it to work, is there anywhere that I should put the binaries and/or patches/HOWTO for public consumption?

P.S.  I should explicitly thank Eric Schnoebelen as the guy who was kind enough to send me the patches for Amanda under HP/UX.  Thus far, I've seen nothing wrong with them, but rather with my "development" suite (ha!) under HP/UX.  See
http://www.google.com/search?q=Amanda+HP%2FUX for the dialog.
