An area of networked disk on server bell is available for
Phonetics and Linguistics staff members to back up a selected area
of their departmental PC disk.
The disk space available for each staff member is 1GB. (1GB =
1000MB). This is intended for backing up a selection of important
files which are likely to change from time to time. Space cannot be
provided for backing up the whole of a PC disk.
To use this networked disk space to create a reliable backup system,
the following is recommended:-
Choose one area on your PC disk to hold the files and folders to be
backed up. For example this could be a folder in Windows under 'My
Computer', 'My Documents'.
Use backup software on the PC which can be set to perform a daily
backup automatically at a time when the PC is likely to be switched on.
Suitable backup software is supplied with Windows XP and 2000. There
are also many other pieces of backup software, some available free. Any
used should be able to perform full and incremental backups so that a
history of backups performed can be tracked and particular dated
versions of files restored if necessary. Attempting to manually copy
changed files on a PC to an external backup area is likely to result in
unsatisfactory backups as it relies on your memory and being aware of
potentially complicated changes in files and folders.
When the first backup has been made, test that it can be restored
using the restore function with the PC backup software. Restore to a
different folder from where the backup was made to prevent potential
damage to this if the backup was corrupt. Ensure that the restored data
can be read.
Ensure that the area on the PC disk to be backed up is less
than 1GB in size. If it is not, your quota
on the networked disk backup area will be exceeded preventing the
backup from completing.
You will be automatically sent an email message early morning if
the data in this area exceeds
1GB. No more will be written here if it exceeds 1GB + 10MB, or more
that 1GB for 7 days.
The instructions below are for setting up automatic backups of a
selected area of PC disk using the backup software supplied with Windows 2000 or XP. Please
get assistance if you don't feel confident to set this up yourself.
INSTRUCTIONS FOR
USING
WINDOWS BACKUP PROGRAM (2000 or XP) TO BACKUP PC FILES TO DEDICATED
BACKUP AREA
ON SERVER BELL
1.0 Accessing
the Backup Disk on Server bell
The PC
needs to be
able to access the networked disk on computer bell to
carry out the backup. Therefore it is necessary to ensure
that the network connection is made at boot up.
1.1 Window
2000 PCs simply
require
the directory \\bell\backup
to
be mounted:-
Right
click the My Computer icon, select Map Network
Drive, and in the resulting dialog box type \\bell\backup in the Folder box, tick the Reconnect at logon
box and click Finish. After this the user will be
prompted to connect to the backup area each time the PC is booted.
1.2 Windows
XP PCs
Windows
XP will
not, by default, prompt to logon to the networked drive. The following
procedure is required in order to make this happen:-
1.21
Search for computer bell and when
found drag onto the desktop. This will put the executable file Samba Server (bell) in the directory
C:\Documents and Settings\Pc_users_name\Desktop. To execute this file
at bootup
its name and path needs to be inserted into the registry as described
below.
1.22 Click Start then click Run.
1.23 In the Open Box type regedit
and then click OK
Save a
copy of the
registry by clicking on My Computer in
the left window, file, export then
select somewhere on the local disk to
save this registry copy to. You will need to give the registry copy a
suitable
filename.
1.24 Move down the tree of folder icons in the left window:- HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer\Run.
(If Explorer is not present it can be
created by clicking policies and
then selecting Edit, New, and left
clicking Key. This will create a new
highlighted entry under policies called New
Key #1. Change the name New Key #1 to
Explorer. Use the same method to
create Run within Explorer).
Double
click on
folder icon Run.
1.25 The right window should now contain the first line
beginning ab as shown and possibly additional
lines beginning ab, eg
ab1
.. ab2 etc:-
Name
Type
Data
ab(Default)
REG_SZ (Value not set)
1.26 Right click below the last line,
then move
inside the box containing New and left
click on String Value. A box will appear
containing New Value#1 with a
blue background. Left click inside this box to the right of the blue
area.
Delete the box contents using backspace key. Type in 1 if
the line above is ab(Default)
or a number one higher than any numerical suffix to ab in this previous line.
1.27 Double right click on the entry just added then left
click on Modify
and enter:-
C:\Documents
and Settings\pc_username\Desktop\Samba Server(bell).
This
entry must be
exactly as appears in the name associated with the bell icon you
dragged onto
the desktop in 1.21 above and may
differ from the example given here. Now
click on ok.
The
right window
should now look the same or similar to:-
Name
Type
Data
ab(Default)
REG_SZ
(Value not set)
ab1
REG_SZ
C:\Documents\andSettings\pc_username\Desktop\Samba
DO NOT EXIT THE REGISTRY EDITOR WITH INCORRECT VALUES
ENTERED AS THIS MAY PREVENT THE COMPUTER FROM BOOTING. RIGHT CLICK TO
MODIFY OR
DELETE IF YOU HAVE ENTERED INCORRECT VALUES. IF THERE IS A REBOOTING
PROBLEM
YOU WILL NEED TO BOOT OFF A WINDOWS XP CD AND IMPORT THE SAVED REGISTRY
COPY.
1.28 Click on file, exit to exit
the registry editor and save the additions just made.
The
user will now
be prompted to logon to bell at bootup.
2.0 Configuring
the Backup Program
There
are a number
of options in configuring the backup program. These are:
1) The
type of
backup
a)
b)
Incremental -
only files that have been created or changed since the last normal or
incremental backup are copied. The archive bit of a file is set after
the
backup.
c)
Differential -
only files that have been created or changed since the last normal or
incremental backup are copied. The archive bit is not set after the
backup.
Incremental
backups result in less data being backed up each time but the last
normal
backup and all subsequent incremental backups are required in order to
restore.
Differential
backups result in more data being backed up but only the last full and
last
differential backup are required in order to restore.
2) The timing of the backup, e.g. once only,
scheduled at fixed periods of time or after the PC has been idle for a
certain
time.
3)
Whether the
backup file(s) on bell is(are) overwritten each time a backup is made
or
whether each new backup is appended to earlier backups. The choice will
depend
on backup type, total amount of data, and change in amount of data
between
backups.
The
configuration
described below schedules a weekly full backup and a daily differential
backup.
There
are two ways
to use the backup menu system for configuring backups. Section
