Yes, I have seen problems with subsequent ndmp backups after one gets
interrupted mid-stream.  However, in my experience it only affects the

you can share?  I'm sure you've tried this, but have you rebooted the
Legato server?  Have you tried labeling fresh tapes for the ndmp pool?



Yup, we've tried rebooting our Legato server..

We are attempting to test this out by running backups on our smallest
(least data) NDMP client (which was not even being backed up at the time
this interruption ocurred). We also rebooted the NDMP server. We get
errors that look like:

OK, I figured you had done that, but sometimes you just gotta ask :-).

Here is what I know about this.  The messages that contain the NDMP
Service Log:  are just lines that are logging the stderr from the ndmp
client.  I sure would like to have a look at the 4 lines that got
suppressed.   Only way I know of to see that is to run a client manually
from the command line.

Example:

savegrp -c client -G ndmp
