Enhancements
------------

New features were added to MRBackup after the user manual was printed. They
are described in this section.


Keep/Suppress Empty Directories Option

You  will  notice a new button on the main window which is not described in
the user manual:  Keep Empty Dirs.  When this button is clicked, it toggles
to  display "Suppress Empty Dirs".  When Suppress Empty Dirs is active, all
empty  directories  or  directories which contain no selected files will be
omitted  from  the backup.  This is a sometimes-desirable option which must
be used with care.

To accompany this new feature, a new ARexx command has been added:

    KeepEmptyDirs <yes_or_no>

This  command  will  allow  you  to  set this option from within your ARexx
scripts.


Tips
----

To  enhance  the  performance  of MRBackup Professional when doing AmigaDOS
compatible backups, increase the number of buffers available to your floppy
disk  drives.   Naturally,  this  will  depend  upon  the  amount of memory
available on your system.  One buffer consumes approximately 512 bytes.  As
a  suggested value, try adding 100 buffers to each drive you intend to use.
To do this, use the AddBuffers command.  Here is an example:

    AddBuffers DF0: 100


When file compression is enabled, files are first compressed to a temporary
image  in  the  directory  defined  by  the  logical  name "T:".  If T:  is
assigned to your hard disk, compression will consume more time than when it
is  assigned  to  memory.   To  reassign  T:   to memory (RAM disk), do the
following:

    MakeDir RAM:T
    Assign T: RAM:T


At the end of your backup, you are requested for the name of the file where
your  catalog may be stored.  Catalog files may be stored anywhere, but you
should  choose  a filename that is easy to remember and associate with each
particular  backup.   MRBackup  suggests  using  the Backup Prefix with the
suffix  ".cat"  appended.   In  the  event  that  you  misplace your backup
catalog, all is not lost!  Many of you are apparently unaware that MRBackup
provides a Rebuild Catalog command which will reconstruct a missing catalog
for you.
