RE: VSCAN and Backsups - toasters

      We have our backups set to run over CIFS shares that have the vscan
disabled. We can backup at faster speed and the filer is still
protected. We found it easiest to duplicate all of our root shares in
this manner.
cifs shares -add <sharename> <path> -novscan or -novscanread

I may stand corrected, but I don't believe the part below is true.  I
don't believe the real-time settings on the Trend server have any
bearing on which files are scanned.  From what I see, it appears to me
that the Netapp decides whether a file should be scanned or not, and
then sends a specific manual "Please scan this file" request to the
Trend server.
The Netapp is supposed to "cache" which files have been scanned and
verified as clean, I believe, so static files shouldn't be slowing down
the backup process once they've been scanned the first time, no?

 I think you said you were using trendmicro as the scanning server. If
you are try setting your realtime scan to "incoming" only. I think this
should improve your backup speed somewhat as the backup file read
requests will no longer require a VSCAN before the file is handed over
to the backup client. The problem here is that you need to be sure that
all of the content currently on your filer is virus free. Because from
now on, only incoming files will be scanned. Its not ideal. Would be
nice if you could exclude your backup client from virus scans during
file open requests. I don't know of trendmicro offering this.
