[Bacula-users] feature request For next years vote - NDMPv5

[Florian H. <flo...@gm...>]

Hi all,

I'm still unsubscribed from the bacula lists from my holiday last may,
so I missed the vote this year, but according to the web site this is
just the right time to submit. :)



anyway...

Item  41:  NDMP Support
  Date:   20070204
  Origin: Florian Heigl <flo...@gm...>
  Status:

  What:   Add basic NDMP support to Bacula Director

  Why:    NDMP is used for offloading the transfer of actual backup
data from the backup host, which is only controlling the media and
storing metadata (i.e. filenames, sizes, ...)
This is a feature which offers great performance benefits (think
100MB/s instead 2MB/s ) of  when dealing with large amounts of very
small files and especially needed for 'appliances', i.e. NetAPP.
It's a standard protocol thus supporting it will mean support for a
range of new devices.
Lastly, I've seen 4 people asking about bacula and NDMP support just
over the last 4 weeks in different web forums. so every thread that
comes up has one person asking about NDMP.

  Notes:  I think this should be not too hard to implement and interesting too.
 Probably not too much new code has to be written, as bacula already
has the fd split into another component.
 This must also work for restores :)

---- Note below ---
 Example with each components job:
 director: initiate session with appliance via ndmp
 director: tell sd to tell jukebox to put a tape into a free drive
connected to the appliance
 sd: put the tape in
 director: tell appliance to mount tape and check label
 appliance: tells director it doesn't find a tape
 director: tells sd to put in another tape
 director: emails operator to pick up the dropped tape
 director: tell appliance to mount tape and check label
 appliance: tells director label and ready and mounted
  director: tells appliance what to backup
  appliance: backs up what's requested to tape and streams everything
besides pure data to director.
----- Note right here ----
When I think about it, the tape is still to be written in a
bacula-native format, so a certain bit of information is missing
somewhere in the above. But I suppose whoever picks this will know it
anyway. otherwise I'll dig into the specifications on request.


Regards,
Florian
