I have novell 6 service pack 5 and brightstor arcserve 9.01.

Whan I do a backup of my volume I have this error:

Failed to begin scan for directory volume:\networ~1, ret=fffdffd1, conn=2

The correct name of this directory is : network trash folder.
Why the name of the directory is break off?

This error doesn't happer for each directories but only on this.

Which is the purpose of the directory "network trash folder"?

it is necessary to backup the directory "network tash folfer" ?
Must I do it?
