What do I have to back up before I re-install?

Question

It seems that almost every time I re-install windows on my PC I end up forgetting to back up something. Now I consider myself an experienced pc-user, and I've done this tons of times, but it never ceases to amaze me how often I forget to backup something (sometimes important, sometimes trivial). I take it that it's usually because from the time i decide to re-install to when i start is pretty short, which really isn't a good thing

What I'm looking for is to build a checklist of common backup-todos before making a full re-install so that this hopefully won't happen again.

Update: To clarify a little, I'm interested in a good BASE-checklist I can use as a start. Which cover as many important components as possible. ie: Browser settings, Email, passwords, Contacts etc..

There will always be user-specific customization (apps, skins, plugin settings etc) which cannot be covered by this type of checklist, and that's ok.

Answer 1

• Password database (e.g. PasswordSafe)
• Accounting data (Quickbooks, ACCPAC, Pastel)
• Any important account / login details
  • Paypal
  • Online banking
• E-mails
• Calendar, appointments
• All documents (word processor, spreadsheet, presentation, PDF)
• Video, audio files
• Any media library databases (Windows Media Player e.g.)
• Serial numbers / details for unlocking purchased software
• Downloaded software
• Device drivers
• Browser bookmarks
• Databases (MS Access, SQL)

I recommend a program like SpaceMonger (there are free equivalents, I just prefer this program) which will scan your entire drive, and can present a list of all files by type. Then simply go through the file types that are important and you shouldn't miss too much.

As for registry settings etc, I haven't tried it, but it may be worth looking into the built-in files and settings migration wizard in Windows.

Personally, I never reinstall without taking a full disk image of my existing OS...onto an external USB drive usually so it stays out of the way of your reinstallation.

So many times, I have needed something that wasn't in the directories I would have manually backed up.

Good hard drive imaging software would be Acronis True Image or Norton Ghost.

Usually with these programs, you can browse through a copy of the image afterwards from your new OS and just pick out the particular files you need without having to restore the entire image.

I backup:

• my drivers, making installing easier (and browserless)
• my antivirus installer!
• program installers that are worth re-installing (or download them again)
• program settings that only require copying folders
• documents/pictures and other random files that aren't on a different drive
• PST files so I don't have to redownload or lose email
• browser settings like bookmakers (yes yes I should get that done online!)

That's about it

Edit: thanks for the email comment

If you re-install a lot, you might consider making a backup or image of your base install once you have installed your key applications, before you start using it. This will become a lot easier in windows 7 as you will be able to make a VHD file and use the boot to VHD feature to load the feature.

As to what to backup, it really depends on how much you customise windows and where you put everything.

I would recommend to take the time to audit your installed programs in program files, and write them down as a clean re-install also presents an opportunity to remove files that you don't need.

Depending on how much success you had with your last installation, you might want to take the time to prepare driver disk that has all the latest drivers for your hardware that you have installed on the system.

You should probably do a full backup anyway, just incase something goes wrong.

The mac has this great feature that you can re-install using your last time machine backup, it is shame that windows doesn't have that feature.

Since I keep my stuff within my user profile and not start randomly creating directories or stuff in the root of the partition it's relatively painless in that I just need to copy my user profile to another disk before reinstall and copy it back again.

I usually make a list of software to install and in which order, though. This helps getting a fresh install up and running within one afternoon.

Starting with Windows Vista there is also a tool that helps migrating everything you have onto a new installation. A friend tried it out when installing Windows 7 and it worked great.

Answer 6

• browser settings(bookmarks, noscrip-whitelist, adlock-blacklist)
• game saves
• documents (all of 'My documents')
• setting folders (under 'application data')

Most of this usually sits under the user profile directory.
