SP5 fixes what SP4 broke???

I think they fixed some of the IP issues in SP4 and further fixed them in
SP5.

However I think it may have more to do with your network and someone
changing some switch and NIC settings.  This sounds more like you were
having issues with duplexing and someone fixed them by hard setting your
card and switch to full full, and now you are seeing that performance gain
and it just corresponds with the SP5 installation.

I have seen SP3 and SP4 boxes get closer to 10GB and hour with NBU

Just a point of interest here, We have noticed that most of our
NT servers (25 active clients) require NT SP 5 to perform well.
We can backup and restore fine to SP 4 systems.  But the performance
goes from < 1GB /hour to 6-10 GB hour by applying SP 5.
Serious performance increase.

Anyone have an explanation?

Hello all,

  We have a situation where we are migrating some NTFS filesystems, and they
are using NetBackup to accomplish the migration (I have suggested other
ways!) The problem is that some of the directories that we backup are
compressed using NTFS compression. When NetBackup restores the files, are
the files restored compressed or uncompressed. (We're moving a 45GB
partition with some directories compressed to a 48GB partition. You see the
likely problem.)

  We, or I, don't really understand the interplay between NTFS and it's
compression architecture, and how NetBackup plays with NTFS.

  We are using NetBackup 3.2 (patch J0820326) on an HP LH3r server (NT 4.0
SP5) and all clients are running 3.2 on NT 4.0 SP4 or SP5.

    Bryan
