Hi Joe,

There is an option for the Include stanza of a Fileset:

sparse = yes

Which works correctly with sparse files. We had to add this option to one of
our filesets when a newer version of of our mail server changed one of its db
files to  sparse file.

Not sure. Unless the code that deals with sparse files adds additional
overhead when it is typically not required.

With our setup, I have _one_ file that is sparse so it is excluded using the
wild = option in the bigger Include stanza of a Fileset, then Included
specifically in a File =  option in the second Include stanza which has the
sparse = yes option.


Maybe someone else can comment re: default being sparse = no

Hope this helps.

Bill
