Purpose
This first automatic back up feature, if enabled
(checkbox ticked), is designed to allow you to recover your work
after a power failure, program lock-up, system crash or other
abnormal method of exiting WordPerfect -- such as shutting
off the computer while an unsaved document is still open. It is not a replacement for deliberately
saving your files periodically.
In fact, it merely creates
a temporary backup of each currently
open and changed file
on your drive. These temporary backups are normally and automatically
deleted when either the edited documents or the WordPerfect program
are closed in a normal fashion.
Should you enable it?
Most users will want to have this feature
enabled. It is generally considered to be a Good Thing.
Which time setting should you use?
The 'conventional wisdom' is to set the timed
backup time to not less than 5 minutes nor more than 10 minutes.
As Joell Haugan, a Corel C_Tech, stated:
"Having [backups] come too fast leaves
open the possibility of one backup not finishing before the next
one starts. Hopefully, under normal situations, this wouldn't
happen ... but couple a large file with a busy computer and there
could be a fatal corruption."
Moreover, if you set it to a very short interval
(e.g., 1 minute), you may notice the program slows down or even
stops, while WordPerfect continuously tries to save your work.
The Windows spinning hourglass that appears on your screen might
be indicative of a too-short time setting.
How it works
With the timed document backup feature enabled,
under normal conditions -- that is, when no crash has occurred
-- the feature works like this (at least in recent versions of
WordPerfect; earlier versions should be similar):
When you make a change to an open file --
i.e., when you edit the document you see on screen -- WordPerfect
creates a temporary file with a name like WP{WP}.BK1
in the backup folder named in Tools, Settings, Files.
This file is not created immediately, however:
It is created after a delay that can be specified in the
Tools, Settings, Files dialog. As noted above, you probably
should not set the delay to less than 5 minutes.
In essence, Wordperfect takes a "delayed
snapshot" of the entire edited document and stores it in
a temporary disk file. As long as the original file remains
open -- and even if you switch to another open document --
this temporary file will be automatically updated after each
edit, according to the delay you specified.
[N.B.: The filename is always wp{wp}, but
the .bk extension is numbered (1-9) according to the number WordPerfect
assigned to the original when you opened it. Thus, assuming you
are actively editing several documents, there might be as many
as 9 temporary backups existing at the same time.]
What happens to it (the usual case)
If the on screen file is then saved, or if
it is deliberately closed by you, the temporary timed backup
file(s) will be automatically and immediately deleted. Its
job is done, so there is no purpose in keeping the temporary
file.
This fact is important to bear in mind, since
many users erroneously believe that this temporary backup file
still exists after they have saved the original file, or -- more
likely -- if they have not yet saved the original file and then
go about exiting WordPerfect normally but mistakenly answer
No to the pop up dialog that asks them if they wish to save the
current file. WordPerfect does what you tell it to do: If you
answer No to the dialog question, WordPerfect will not save that
file -- nor will it keep any temporary backup copy of
it. [However, see the second question-and-answer below
for a Windows method that might work to recover such a file.]
What happens to it (the not-so-usual case)
If the WordPerfect program had an abnormal
termination (e.g., a crash or power failure), the temporary
timed backup files created during the previous session will continue
to exist on the drive until you next load WordPerfect; they can
then be used to restore the previously opened and changed files.
WordPerfect will automatically detect these
temporary files and pop up messages when you load the program
to ask you how you want to deal with them. Normally you would
open them to examine them and make a disposition (save? delete?),
but you can also delete or rename them directly from the message
dialogs. If you wish
to save them, be sure to rename them
(File, Save As) or else you could confuse the program later,
and it might start popping up error messages (see next paragraphs
below).
Note the following about abnormal
terminations and these temporary timed document backup files:
1. If you do not delete the temporary timed
document backup, or rename it or save it under a different name,
you might get a message in the next few minutes when WordPerfect
attempts to back up the timed back up file itself. If you try
to delete the file, you might get another message saying you
"...do not have
the rights..." to do this. Close
the open timed back up file and things should return to normal.
2. After an abnormal termination, if you see
the message about a backup file existing and you open it (as
explained above) to save or delete it, and you still get
a message the next time you open WordPerfect (something like,
"..To save the
backup file please open or rename it..."), it is possible the backup folder was corrupted,
too. Here's a tip from Wolfgang Deiminger on the Corel WP12 newsgroup:
"Find the location of the backup folder
(in WP, do Tools, Settings, Files, Document Tab). Then,
with WP closed, use Windows Explorer to delete the folder and
create it again. This should sort things out."
3. If you receive a message that the temporary
timed backup file exists (e.g., "Document 0 backup file exists..."), and even after you renamed or deleted it you still
get a message that this temporary files exists, here's a tip
from Charles Rossiter (Corel C_Tech) that might help:
"[Close WordPerfect.] Use Windows Explorer
[or My Computer] to browse to your specified [timed] backup folder
[shown in Tools, Settings, Files, Document tab, Backup folder]
and delete [the] file wp{wp}.bk!
What probably happened is that you opened
a backup file, and then saved it without changing [the] filename.
This can create the file wp{wp}.bk! ... and give a [Windows version
of a] message about wp{wp}.bk0."
[Update 8/19/2011:] A Corel support database
article (3565) here
indicates you should "Delete all files whose name begins
with 'wp' in this folder."
You can also try renaming that folder,
which will force WordPerfect to create a new, empty one in the
same location, when next it is started.
What happens if you close
the document without deliberately saving it (and ignore - or
answer "No" to - the message that appears that asks
if you want to save the changes you have made to the document)?
This is not considered
an abnormal termination of the program as explained
above, so the temporary timed backup file(s) will be automatically
and immediately deleted.
WordPerfect naturally assumes you want to
discard the changes -- and any temporary timed backup file --
if you ignore, or answer No, to the message.
If you have accidentally lost work because
you failed to save your work when WordPerfect asks if you want
to do so, you might consider using a macro (or third party program)
to help you save your work more frequently as you edit your documents.
See the last section on this page.
Note
Some programs, notably databases or those
that are designed around a database (e.g., Quicken) will automatically
save an entry when you press the Enter key. But word preocessors
do not do this. If they did, and blindly wrote over the previously
saved version of the file while you are editing and experimenting
with various creative ideas ... well, most people would become
very upset over such a loss of the previous material, so WordPerfect
will not automatically save your work in a way that overwrites
a previous version.
[Exception: See the Save
original document as a backup at each save option below.
If this option is enabled, WordPerfect creates one backup
of each saved document on disk, so it will overwrite the
previous backup file (it will have a .BK! filename extension)
on each subsequent manual save. Thus, if the the "Save
original..." option is enabled, the backup it makes
contains a copy of the original file as it existed when the original
was last (manually) saved.]
Can the timed document backup
be used to recover accidentally deleted material from
the active document?
The short answer is maybe.
Let's take an example where a system crash
is not involved, and see what happens as you edit files
on screen and then delete some important material. You might
have done this by using File, Close (and then answered "No"),
or by exiting WordPerfect without saving your work. (TIP: If
you selected some material and hit the <Delete> key, the
best thing to do is use Edit, Undo as soon as possible.)
If you have previously enabled the timed document
backup option, any material in the actively edited file, or any
other loaded file where a change has been made, is temporarily
saved to disk (after the selected time delay) in a file
named something like WP{WP}.BK1, in the backup folder specified
in Tools, Settings, Files.
As mentioned, this protects against a power
failure or crash. It does not save you from yourself.
If you close a file without saving it, or delete so much material
that you exceed your personal settings in Edit, Undo/Redo History,
Options, you might not be able to recover all material. This
temporary timed document backup file would exist only until
you close the edited file or exit the program, whereupon it is
automatically deleted.
HOWEVER ... if you have deleted a lot of material
in the currently open file, you might be able to recover
it if you are lucky enough to be able to open the backup file
before the next timed backup overwrites it. (The edited file
must still be open, or else WordPerfect will immediately delete
the WP{WP}.BK* file.) Try navigating to your WordPerfect temporary
backup folder [shown in Tools, Settings, Files, Document tab,
Backup folder] with Windows Explorer or other file manager,
and copy the temporary WP{WP}.BK* file to another folder, where
it can be renamed.
Notes
1. Recovery of any material from a deleted
WP{WP}.BK* file might be possible with a separate file
recovery program (such as the old Norton Protected Recycle Bin
program or Undelete+
[neither of which have been reviewed by this author]) if recovery
procedures are instituted before anything else is written to
disk. Obviously, the best approach is to avoid getting into
a situation where you need to take such measures.
2. If you keep getting an error message, "The specific backup folder no
longer exists," try this (originally
from Answer ID 754208 at http://support.corel.com):
"... This error message is usually caused
if WordPerfect can no longer write to the backup folder or the
folder has become damaged in some way.
The easiest solution to this problem is to
reboot your computer and try WordPerfect® again. If problems
persist, rename the location of the backup directory. To do this,
follow the instructions listed below:
(1) Go up to the Tools menu and select
Settings.
(2) Click on the Files button and select the Document
tab.
(3) Type 'C:\Backup' ( without the quotes ) in the Backup
Folder box.
(4) Click on Ok. Click Yes to create the directory if your prompted.
NOTE: To prevent this problem from occouring
in the future, ensure that your virus scanner is NOT checking
the WordPerfect backup file directory."
