You can set the system environment variable "NSR_AVOID_ARCHIVE" to a
non-null value on win2k and winNT client systems.  This requires a reboot
of the client system but will cause NetWorker to ignore the archive bit's
value when determining whether a file has changed in some way other than
modtime and checksum.  This configuration change has saved us *hundreds* of
GB of needless backup every night while providing the necessary coverage.

On the NetApp its only windows-data via SMB.

Ah. Is there any good way around that? In order to get level 1-9 backups
to work as expected? What kind of file access changes the archive bit?
Read access or does the file need to be opened with R+W? Or is an actual
change necessary to set this bit? Is that up to the client or the server?
