Backup/!Backup/!Help
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

Backup
======
(C) Martyn Fox 1997
===================
This application makes it easy to maintain a backup copy of your hard disc
on some other medium.
A variety of large-capacity removable media formats are now available such
as Jazz, Zip, PD (e.g. Cumana Proteus) and Syquest drives. These can be used
to keep a safety copy of all or part of your hard disc en masse.
Alternatively, parts of the disc can be backed up on a series of floppies.
Making a backup copy is, in itself, simple. You just have to copy everything
from the source disc to the backup with the �Newer� option set (this can be
done via the �Options� submenu from the Filer window menu). This means that
you don�t waste time overwriting files which haven�t changed since the last
backup.
Problems start to arise, however, when you delete unwanted material from
your hard disc. Unless you remember to delete them from your backup as well,
the backup will become littered with old files that you thought you�d got
rid of.
This application deals with the problem by comparing your hard disc (or the
portion which you wish to back up) with the backup disc. Anything which
exists only on the backup is moved into a special directory, leaving you to
decide what to do with it. Any part of the disc can be covered, from a
single subdirectory to the entire hard disc, using a backup medium of
sufficient capacity. All operation is multi-tasking, so other multi-tasking
applications can run at the same time.
Special features of the software make it easy to back up any of the
following;
� An entire hard disc to another disc of suitable size.
� Any portion of a hard disc to a smaller disc, by selection of the
appropriate subdirectories.
� A portion of a hard disc to the corresponding part of a backup disc
which has a similar directory tree.
� Any directory or group of directories to a floppy.
Two basic principles are observed;
� Nothing is altered on the source disc, which is merely read.
� Nothing is deleted from the backup disc; objects are simply moved.
If an object is found on the backup disc which is not present on the source
disc, a special directory is created in the top directory of the portion of
the backup disc being checked. By default, this is called �++Backup++�,
though you can change this name if you wish. Any object not on the source disc is moved
into this backup directory, with its original directory path being
duplicated within the backup directory. This feature makes it easier to tell
where an object came from when deciding whether or not to delete it. Any
object which is a file on one disc and a directory on the other is treated
in the same way.
Using Backup
============
The application is started in the usual RISC�OS manner by double-clicking on
its icon in a directory window. As well as an icon appearing on the icon
bar, the application window will open. This window may be closed at any time
by clicking on the �Cancel� button and reopened by clicking on the icon bar
icon.
You can back up several subdirectories from the same parent directory in one
operation by selecting their icons with the Adjust button and dragging them
to the top part of the window. The way in which the application works is
slightly different if you drag more than one icon. If you want to back up
the contents of one directory, you can drag the directory icon from its
parent directory window to the top part of the !Backup window (anywhere
within the box surrounding the top writeable icon will do). Alternatively,
if the directory�s own window is open, you can drag any object from within
it with the Shift key held down (the key must be down when you release the
mouse button). If you want to back up the entire disc, drag any object from
it, then click on the top �Root� button.
If you only dragged one icon, the pathname of the directory to be backed up
will appear in the top writeable icon. You can then click on it and modify
it by typing and deleting. You must, though, end up with a valid directory
pathname or the software will attempt to back up the contents of a
non-existent directory.
If you drag several icons, the pathname shown will be that of the
directories� parent followed by �.<Selection>�. The Shift key will have no
effect and you will find that you can�t modify the contents of the icon. You
can, however, drag a new icon to the window to reverse this situation and
you can still use the Root button.
After you�ve set up the pathname from the source disc, drag any object from
the backup disc to the bottom part of the window. The pathname which appears
will be identical to the source pathname, but with the name of the source
disc replaced by that of the backup disc. This makes it easier to back up
part of a disc onto the equivalent part of another disc with a similar
directory tree. This pathname may also be altered by typing or with the Root
button.
The operation is in two stages, Purge and Copy, either or both of which can
be selected by the two buttons on the right-hand side of the window. Purge
is the process described above, moving objects into the backup directory,
and is always performed before Copy if both are selected. Copy is simply the
process of copying objects from the source disc to the backup with the
�Newer� option set. All file moving and copying is performed by the RISC�OS
Filer Action application.
When you are ready, click on the �Start� button and the process will begin.
A further click on this button during the Purge operation will suspend the
process. If you want to stop during the Copy stage, you should click on the
�Pause� button in the Filer Action window.
The backup directory is only created if there is an object to be moved. Its
presence is checked for at the start of the operation, which will not
proceed if it is present. If this happens, you can proceed either by
deleting the backup directory (after doing something with anything in it
which you want to keep) or by choosing a different name for it � this will
probably result in the original backup directory being purged into the new
one.
No special provision has been made for archives but an open archive can be
handled the same as an ordinary directory.
The application initially uses a Wimp slot of 64k. After initialisation,
this is reduced to about 36k on a Risc Pc. The amount of memory required
during operation depends on the depth of the directory tree being checked.
The program takes just a few k for each directory level and gives it back
when it has finished with it.
Acknowledgements are due to my son Alexander Fox who designed the
application sprite and made several programming suggestions.
