Backup Central

Amanda 3.1.2 on Solaris 10x86.

Occasionally we see this failure, even when the prior run
ends cleanly.

I'm not sure how amanda handles it,
does sit fail to create the snapshot ?
does it destroy and then create a new snapshot ?

It did successfully backup the DLE.

Can you find in the debug files why the destroy failed in the prior runs?

It doesn't destroy and recreate the snapshot.
The backup use the snapshot, so it backup old data

destroy and create is probably good in case of 'dataset already exists',
can you post a patch?

It sounds simple enough... and I figured out how to apply
a patch yesterday. I was so close, needed gpatch rather than
patch, I was so proud. [else you get these weird errors]

Jean-Louis,

I involved Dave Remling at my site, his Perl being far better
than mine.

We actually has a large number of broken pipes, which began
with 3.1.2's installation, the next day things ran somewhat
better and all of the prior day's snapshots where cleaned up
at the end of that second run.

Wondering if the left over snapshots are a side-effect of the
broken pipe issues ?

If so, is that fixed in a more recent amanda snapshot (unfortunately
collison of terms) or in 3.2.0 ?

If we, will will build and install that and then see if we need
to patch the perl to fine/destroy/recreate snapshots.

thank you,

Brian
