Well there are a few ways to do this...

you could: 
make a screen buffer. 
store the background in the screen buffer.
blit the buffer to the screen.
blit sprite to screen.

this might have flickering in it though.

a better way would be to: 
make 2 buffers.
store the background on the first buffer.
blit the first buffer to the second buffer.
blit the sprite to the second buffer. 
blit the second buffer to the screen.

This doesnt have flicker(assuming that
your blit to screen waits for retrace)
but uses more memory.

allegro might help you in such a task.
