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 normally are 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 or abnormal program termination has occurred -- the feature works like this [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 current document on
screen -- WordPerfect creates a numbered, temporary file on disk with a name like wp{wp}.bk1, wp{wp}.bk2, etc., in the special backup folder specified
in Tools, Settings, Files, Backup folder. (Note this is a different disk location from the one used by the "Save original document" backup feature, as explained below.)
This
temporary file is not created immediately: It is only created after the
delay specified in the Tools, Settings, Files dialog.
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.
Notes
1.
Since the program can open up to 9 documents in a single instance
(WordPerfect X6 can open several instances), the digit on the end
of the filename will correspond to the
document's internal number assigned 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.
2. The
filename and extension format above is quite different from that
assigned to the "Save original document" backup described below. Furthermore, these temporary files will be stored in the backup folder named
in Tools, Settings, Files -- not in the folder that contains the document being edited.
3. As previously noted, you probably should not set the delay to less than 5 minutes.
What
happens to it ... in 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 retaining
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 ... in the not-so-usual case
If the WordPerfect
program had an abnormal termination (e.g., a
program freeze or crash, a power failure, or the computer was powered off before saving open and changed files), 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 a message as soon
as 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 (i.e., save
or delete), but you can also delete or rename them directly from the
message dialog.
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 the next
paragraphs).
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 timed backup folder was corrupted, too.
Here's a tip from Wolfgang Deiminger on the Corel WP12 newsgroup:
"Find the
location of the [timed] 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 [timed] 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:] An old Corel support database article (754080 and 3565)
indicated you should "Delete all files whose name begins with 'wp' in
this folder."]
You can also
try renaming that folder on
your disk (using Windows Explorer), which will force WordPerfect to
create a new, empty folder in the same location the next time WordPerfect
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
copy of each saved document on disk, so it will
overwrite the previous backup file (such files 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 while 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 file being
edited must still be open in WordPerfect, or else WordPerfect will
immediately delete
the wp{wp}.bkn file (where n = a number from 1-9).] 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}.bkn file to another folder, where it can
be renamed to a more normal name.
Notes
1. Recovery of
any material from a deleted wp{wp}.bkn file (where n = a number from 1-9) might
be possible with a separate file recovery program (such as Undelete+
[not 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 [you are]
prompted.
[N.B.: On some
systems you might need to first
create an actual folder of that name and location on disk with
Windows Explorer.]
... To prevent
this problem from occouring in the future, ensure that your virus
scanner is NOT checking the WordPerfect backup file directory."
