I need 2 scripts.

1.  I plug in my external drive. Double Click on something(like a .vbs). And automatically backup everything that user needs before i wipe it.(I believe that would be the documents and settings folder)
2. I plug in my external drive. Double Click something. And automatically everything is restored.(My documents,- word docs, ppts, pics,etc, that was on there desktop-,IE Favorites, Firefox Favorites)

You'd be surprised how good the files and settigns transfer wizard in Windows it:
(info here:)
http://www.microsoft.com/windowsxp/using/setup/expert/crawford_november12.mspx

Other option is maybe disk imaging software:
Paid, but good:
Acronis Trueimage
http://www.acronis.com/homecomputing/products/trueimage/

Free, and apparently okay:
DriveImage XML: http://www.runtime.org/driveimage-xml.htm
iRestorer: http://irestorer.parsaspace.ir/


Hope this is of some help.

So who's to stop the client from saving important personal data in C:\Joe's Cool Stuff?

Or what if they downloaded a cd ripping program that stores the ripped files in C:\Program Files\AwesomeRipperPro\output ?

Restoring a user's personal files after wiping their computer is a manual task. Typically the My Documents, Favourites, and a couple other minor things cna be done automatically, but everything else has to be done by hand.

For that reason, it is crucially important you have a FULL bare metal backup of the computer before you start reformatting it. That way, when the client comes back two weeks later in a panic because they just realized half their music collection was actually not in the My Music folder, or that their entire company financial records was stored in the \Program Files\Quickbooks folder, you have the data and don't get into a mess.

That said, I do two. First I use driveimage xml to make an image-based backup. DriveImageXML is great if you need to restore windows in it's full glory - boot record and all.

Then I use robocopy to make a file-level backup of every file. I just do the latter so that it is fairly painless to copy the files back later. Again, with robocopy.

I use the attached code to set-up backup for clients - a script I wrote.

If you put it on a USB drive, you need two other files:

backup.cmd:
cscript backup.vbs

autorun.inf:
[autorun]
action="Backup Documents and Settings"
open=backup.cmd


Save the files above (they are just normal text files just rename as shown), then when you insert the USB drive you are offered the option to backup.  By default it copies everything in the Documents and Settings folder to a backup folder on the USB drive.

So that is part 1 of your question.  Part 2 should actually be another question.  However, the code below can easily be modified to do part 2 too.

The advantage of using the script below (in my opinion) is that it doesn't crash (any errors it will just carry on), it doesn't copy files that don't need copying (so runs much quicker after the first copy), and saves the files in a way easily recoverable (i.e. doesn't need third party software to read an image file).

Though it must be said, I agree with Frosty555's comments in this case.  If you are wanting to use this kind of thing before wiping a computer, you need a full image - you cannot presume that everything you need is under Documents and Settings.  Or anywhere, in fact.  I'm often amazed where people put things, and also where little known programs or such store their configuration data (and of course, it's too late to check these things once the machine is wiped...).

While the above script could also be reconfigured to backup the whole drive, it would fail at any files that are locked (where imaging software wouldn't).  So the backup couldn't be considered complete.

Yeah, the script above can be considered a time-saving utility, but not a rigorous backup by any means.

Still though, I just use robocopy to copy the whole hard drive. It's real easy:

ROBOCOPY C:\ E:\Backups\SomeClient\CDrive /e /zb /r:3 /w:5 /v /eta /XD "Temporary Internet Files" "C:\Recycler" /XF "pagefile.sys" "hiberfil.sys"

That copies everything from the C drive, retries up to three times per file but persists through if it fails, and doesn't copy the Temporary Internet Files, Recycling Bin, or pagefile/hibernation files.

Though Robocopy also fails on locked files, which can be a major issue when doing a full-system backup.  For example, database files will often be locked if a program is accessing them... yet they contain a lot of data, and are definitely files that need to be copied.  So for a true backup, I would say you need a utility that backs up with shadow copy, or force a reboot to ensure it can back up the files e.g. TrueImage or similar.

Hey great advice all.  I now have acronis true image, which I can use to backup.  I don't to image though. If someone had a virus i wouldn't want to image a partition with a virus on it(callmecheez)

good point frosty, I figured I'd end up checking the root no matter what :-\   but yea robocopy should work pretty well and if not ill definately end up using it for something.

still figuring that script out pomegranite. looks pretty cool and thanks for the heads up on the database thing, im working on my access skills now.

but great point callmecheez  i had no idea the file and transfer wizard was that robust.
