Yes that was what I was trying to suggest imply ( in I guess not enough words). ( I was also a little confused as to which of the 2 cases you mention were applicable but guessed it was a disk backup because of the "backup piece" wording ).

The symbolic links could be applicable also if restoring from tape and you want to simplify restoring to "the same place" as where the backup came from. ( But I am sure you know that already ). Received on Thu Jan 19 2006 - 14:32:30 CST
