There a multiple ways to back up stuff, I'm assuming you mean the information on the laptop so I'll give you some examples.
Transfer the information onto a memory stick, CDs, Floppy discs (if you still use those things), transfer the data onto a portable hard drive, transfer the data onto your PC, put all the information onto your own securely locked website so that only you can access it, or get someone else to do it for you.
Well you can do it in many ways. You can take backup on a hard drive. If you don't have a hard drive, you can use DVDs or CDs for this. There is also an option of storing your data on internet. There are many websites that offer you storage for free. Only problem with this is that you need a good Internet connection and it may be unfeasible to store large data this way.

it's a system state backup.
To sell a laptop, you will need to erase everything on the hard drive before selling it. There are hard drive erasers available which are free of charge.
Fill formatting allows you to take just the formatting from a cell and put it into a load of other cells, similar to using the Format Painter. You could have a cell with particular formatting on it, and drag it down and pick just to take its formatting, not its value or formula, and fill that into the other cells.
it depends on how many gb it as
No, the backup crew of a space mission is in training and preparing well before the launch. If something happens to a primary crewmember before launch, the backup person may take his place, or the entire mission may be rescheduled.
