Since Access is
constantly changing the database file, you cannot rely on it |
|
|
to protect you from your
own mistakes. You must use Windows
Explorer |
|
|
to make duplicates of
the database file. |
|
|
|
|
| A. |
One method of doing this
is to create a series of versions of the database |
|
|
file. You can number the files according to date
or the sequence in which you |
|
|
created them. This lets you work on your most recent
version. It also |
|
|
lets you "go back
in time" to a previous version, if you need to. |

|
|
| B. |
Before you make the next
version, you should make a working copy of |
|
|
the most recent
version. Then do the next phase of
your development on |
|
|
this copy. Why should you do this? Because if you make a mistake that you |
|
|
cannot undo, then you
still have the original database available.
Your last |
|
|
version has not been
altered. (You modified your working
copy of it.) |

COPY: |

|
|
|
|
|
|
|
| C. |
Later on, when you have
finished a work session on your working copy, |
|
|
it is time to make a
decision. Do I want to keep this file
or destroy it? |
|
|
If you keep it, then you
will rename it to be the next version of the data- |
|
|
base. |

COPY: |

|
|
|

|
|
| D. |
If you think you were
better off before you made changes to the working |
|
|
copy, then throw it away
and start over. In other words, make a
fresh |
|
|
working copy. |

Now, you might be
asking, "What should I do with all those old |
|
|
versions?" I would say, "Save them!" First of all, you can put them in |
|
|
a hiding place--a
sub-folder called Old Versions. Second
of all, don't |
|
|
forget, that the only
true backup is a file saved on a separate device. |
|
|
If your time is
valuable, then you should preserve your effort by copying |
|
|
everything to another storage medium. |

There are many options
for |
|
|
backing up files. |
