How do I safeguard my iphone contacts and applications if I reformated my computer?

Here is my problem. The computer I synced my iphone with has been reformated, therefore my computer now no longer recognizes my iphone and wishes to erase and sync.

My contacts were saved on my computer before it was reformated. I dread that if I let my computer sync, then it will erase all my contacts since my reformated computer no longer carries the past data.

How do I save and renovate my contacts and applications without having to do it manually?
