I did once look into all of our Status 1 results and had several along
the lines of "it's a WINS server and the WINS DB failed" ... sounded
important to me.  Unfortunately, Status 1 is still at the bottom of my
list of things to look at in terms of priority, because there are too
many things above it :-)

Status 1 is not a failure UNLESS it's a database backup.  For
filesystems everywhere I've been we've shown that a status 1 is not a
failure but a warning.  Unfortunately you won't get Veritas to
officially confirm that.

Some things I've seen cause a status 1: 
Open files.
Files changed between the time the list for backup and the actual write
to tape occurred.
Sun "Door" files.

We verified extensively at a job that required FDA Validation that
restores from such backups were indeed complete to the point in time the
backup was started.  At that job we simply had to document that a status
1 was a success for all but database backups.

Note that due to the status 1 scheduling tools Tivoli Work Scheduler
(Maestro) that show abends for non zero exit status need to be massaged.
You basically have to have the Maestro job script check for status 1 and
mark exit the script with status 0 to prevent this.  "exit 0" is all you
have to do in a script to make this work.  It took me a while to get our
schedulers to understand this concept but once they did and I gave them
the syntax they were able to avoid reported abends for this.

Bob
As the image is stored in the DB, I still see Status 1 as a good backup.

As long as you can get the data that needs to be backed up, and you
identify
the reason for the "1" you have 2 options in my view:

1) exclude the file/files that are causing the status code
2) Investigate and if not relevant, revert to point 1.

Anything higher is what I class a failure.

> Exclude the "1"'s as I dont class them as failures :-)

Which might be why NetBackup defines stat 1 as "partial success" _and
keeps
the image_.  Final status <= 1 yields a restorable image; status > 1
does
not (archives excluded).  I think we agree that stat 1 beats the heck
out of
stat > 1.

That said, Operations can not accept a stat 1 without investigation.
What is
a status 1--is it one of the 15-odd conditions in the Status 1 section
of
the NetBackup Troubleshooting Guide?  Is it "just another goofy Windows
busy
perfdat file?"  The definition Ops must apply is "of all the files which
were to be backed up, some were and some were not."


Example A:
Files to be backed up (seletion minus excludes plus includes:  1,000,000
Files backed up:  999,999 Files not backed up:  1
Status:  1

Example B:
Files to be backed up (seletion minus excludes plus includes:  1,000,000
Files backed up:  1 Files not backed up:  999,999
Status:  1

Hence the BBP requirement that intelligence, artificial or human, be
applied
to stat 1s every time.
