Sitting here in the middle of the night I came to think of an idea that would bring Ubuntu, and thus GNU/Linux infinite advantages over Windows.

Could it be possible, during install of Ubuntu, to create a Salvage-partition on which the system via automated function could make a backup of a users documents and pictures so that if the user deletes a file by accident there will be a backup of files that are say up to a year old? Or what ever limit could be agreed upon.

A function asking the user to specify a time of day when the computer WILL be on, in order for the system to run the background backup of newest documents and picture files.
After the backup is done, the system should unload the backup program from memory to free the space.
