We can't save your data. You've got to do that yourself.
The usual way: do a regular backup. Then - if this happens - you only have to save the data new or changed since the last backup.
The usual way to save data: boot from a Linux disk (free) and copy everything to a USB-stick (if not much) or an external hard disc (if much).
