If you have a laptop as backup, then that is a second computer. Forget about 2 backup PSU's. Most people here don't know how to replace it, if they do, then they don't need to be told.
Backing up data is of course true, just use a memory stick or an external hard drive. The security is in having everything in two places - either can fail but unlikely both.
Don't go for complicated synchronisation software, just copy and paste the whole of 'My Documents' and keep overwriting your last backup. Or create a folder for each backup.
What do you think about eset's online virus scan?
