Backing up the PST file(s)

[PT]

I recently began using Outlook 2003 on a new Windows 7 Home Premium
Computer. I successfully imported my emails and contacts from an
older Windows XP computer.

I want to have my Outlook data store – the .PST file set up for
automatic backup using the “Second Copy” program. I want to tell the
backup program which file(s) and where.

On the Mail page of Outlook, I used the click sequence

Rt Click Personal Folders
Properties
Advanced

The resulting file name is:
C:\Users\PT\AppData\Local\Microsoft\Outlook\Outlook.pst

But in c:\Users\PT\MyDocuments, there’s another file, PT.PST
I never created this file. The name “PT” is the Windows 7 name of my
computer, and seems to have been picked up automatically.

The two files have the same date and time stamp, but are not identical
size. In particular, the first file is ~61KB, and the second is ~81
KB.

So, my questions are:
Why two files?
Why the different size?
Which should be backed up?

Impossible to say since we have no idea how you created and configured your
Outlook profile nor how you migrated your data, other than you did so
incorrectly. You never import Outlook data.
Obviously you would backup the file that Outlook is using.
