New features that are not documented in the manual
==================================================

MultiCD backup for partitions too big to fit on one CD
------------------------------------------------------
CDbackup v1.2 now supports backing up (and restoring :-)) partitions
larger than a single CD.  MultiCD backup is invoked in the following
circumstances:
     . you are backing up one partition only
     . there is insufficient space on the current CD
     . there is insufficient space on a blank 74-minute CD

Just as with single CD backups, you can backup or restore CDs, with
simulation if desired, and you can list the contents of a CD that is
part of a multiCD backup.

*IMPORTANT*  You _cannot_ mount a CD from a multiCD backup as a
partition, and access individual files from the desktop.  This would
be like trying to read a disk partition that has large parts of it
unavailable.  However, you can restore individual files via CDbackup
(see below).

Individual file restore from single CD or multiCD backups
---------------------------------------------------------
Since the CDs in a multiCD backup cannot be mounted from the desktop,
you can't use the desktop if you just want to restore an individual
file, rather than the complete backup.  This feature allows you to
restore individual files from a multiCD backup.  The Verify/Restore
dialog now has an additional button: File restore.  Load volume 1 of
the backup into the drive, and click on File restore.  CDbackup will
scan the filesystem (FATs and folders) on the mounted CD and, when
it is finished, open a window displaying the contents of the root
folder of the backup.  Click on a directory to open it, or click on
a file to restore it.  It even supports long filenames !!

NOTE: because some of the data is (of course) on the other CDs in
the backup set, not all of the files and folders are immediately
accessible.  If you try to restore a file that exists partly or
wholly on a different CD, you'll be prompted to mount the additional
CD(s) as required.  Similarly, if a folder exists partly or wholly
on a different CD, when you try to access it, you'll see a message
"Click here to continue retrieving this folder".  If you click on
that message, you'll be prompted for additional CD(s) as required,
and the scanning process will resume.

COMMENT: it is possible you may have to go through this process more
than once (a folder on CD #1 could point to a folder on CD#2, which
could point to a folder on CD#1 and so on), but each time the results
are added to the original scan, so you won't lose access to the
original data.

CAUTION: if you close the root folder of the display (by clicking
on the Closer gadget), the window will close and CDbackup will throw
away all the tree info.  So if you decide to get another file from
the backup, you'll have to go through the scan process again.

NOTE 2: although this feature is intended mostly for use with multiCD
backups, it works in the same basic way with standard backups (of
course, with all the data on the same CD, you won't be faced with
swapping CDs).

XHDI support
------------
A new option "Use XHDI interface if available" has been added to
the General options dialog.  If checked, CDbackup will use the XHDI
interface (if available) for low-level access to your hard disk
partitions, instead of the Rwabs() interface which was used in
previous versions of CDbackup.  Depending on your operating system,
you may need to set this option to allow CDbackup to access your
hard disk partitions.

NOTE: the XHDI interface is supported by most current hard disk
drivers including HDDRIVER; however, it is not supported by AHDI
(the original Atari hard disk driver), nor by the ICD drivers.
If your hard disk driver does NOT support XHDI, and you have this
option checked, CDbackup will use the Rwabs() interface instead.

Improved Erase function
-----------------------
You may choose between FULL and QUICK erase: a full erase erases
the entire CD; a quick erase erases just the first session.  A quick
erase is always quicker (sometimes a _lot_ quicker) than a full
erase.  A progress bar is displayed during the erasing process and
the mouse shape turns into an eraser.

NOTE: in most cases, a quick erase is sufficient; however, in rare
cases you may need to use a full erase to prevent previously-recorded
sessions of a multisession CD from "re-appearing".

Miscellaneous changes and improvements
--------------------------------------
 . the speed popup now lists only valid speeds for the selected
   recorder.

 . the progress bar length is now based on the percentage of data
   transferred rather than percentage of estimated total time.  This
   should provide a better indication of progress.

 . displays of disk and CD space in KB and MB now use a factor of
   1K = 1024 rather than 1K = 1000.  This is consistent with usage
   in CDwriter and CD InScriptOr.

 . while doing a simulated backup, you can now abort at any time,
   rather than just at the end of a track.  This is harmless because
   the CD is not actually being written.

 . if you abort a simulated backup, the simulated finalization is
   bypassed (it does nothing except take time).

 . for clarity, verifying/restoring messages now include the letter
   of the backup partition as well as the target partition.

 . the mouse cursor now gives a visual clue to the program's current
   activity: it has a 'writing pen' shape while writing/finalizing,
   an 'eraser' shape while erasing.

 . if you click on any of the backup entries in the List window, a
   form alert will give you the 'vital statistics' of the partition
   that was backed up.  This will help if you need to create a new
   partition to restore to, since CDbackup always verifies that the
   backup and hard disk partition information matches before allowing
   a restore.
