It would would be a nice feature for Networker to give some
warning/error/explanation when it decides to ignore W2K directories
containing billions of bytes of data .
Yes thats whats happening here . Its happened on 2 different W2K servers of
dissimilar configurations. The setup is
1) W2K server running Networker 6.1.2 client (or greater)
2)Solaris 2.6 running Networker 6.1.2 or 6.1.3 server
Heres the ugliness

In one case the drive on the W2K box was 'E:\" in another case "F:\".
In the client setup I said 'ALL' for the savesets. After the backup runs you
see that a particular directory(lets say XYZ) containing in one case 70 GB
data does not get backed up. Review of both server and client logs shows NO
ERRORS/NO WARNINGS . This is not good.Further inspection of the backup
results shows that some of the data on "F:\" was dumped , only XYZ was
ignored.
I then go on to discover that by listing the directories explicitly (F:\A
F:\XYZ F:\FUBAR) every thing gets dumped . This is not a good solution for
obvious reasons .

I have been struggling with this issue since last October. Legato 'technical'
support must not think its much of an issue since I'm the only one reporting
it.(We go through a 3rd party for support).

Is it a Networker BUG? W2K BUG? Networker Config Issue? W2K Security Issue?
W2K Config Issue ? I don't care . I have supplied every log available form
both server and client,every configuration detail from both server and
client. Silence . All manner of back up tests run . Silence

If you have a configuration similar to ours you might want to double check
your back up results.

Heres some real data.

# savegrp -n -c xxxx -G TEST
  xxxx:C:\ 8004 records 1585 KB header 872 MB data
  xxxx:C:\ 874 MB estimated
  xxxx:E:\ 96 records 18 KB header 11 MB data
  xxxx:E:\ 11 MB estimated
  xxxx:F:\ 240 records 51 KB header 424 MB data
  xxxx:F:\ 424 MB estimated
  xxxx:SYSTEM STATE:\ 4 records 1 KB header 0 KB data
  xxxx:SYSTEM STATE:\ 1 KB estimated
  xxxx:SYSTEM DB:\ 4 records 1 KB header 0 KB data
  xxxx:SYSTEM DB:\ 1 KB estimated
  xxxx:SYSTEM FILES:\ 2 records 1 KB header 0 KB data
  xxxx:SYSTEM FILES:\ 1 KB estimated

Notice the estimate for F:\

Now by listing F:\XYZ we see

# savegrp -n -c xxxx -G TEST
  xxxx:F:\XYZ 17689 records 4094 KB header 71 GB data
  xxxx:F:\XYZ 71 GB estimated
  SSSSS:index:8cfbc825-00000004-3d09d4b4-3d09d4b3-04670000-ac112846 352
records 72 KB header 26 MB data
  SSSSS:index:8cfbc825-00000004-3d09d4b4-3d09d4b3-04670000-ac112846 26 MB

Slight difference between 424 MB and 71 GB
