New PS2 user

[TDRN]

I recently got PS2 and was inquiring about backing up games. I think that I have successfully backed them up, but I guess I need something else to verify they backed up and to play them. I have only backed up PSX games to try it out. I haven't tried PS2 games yet. No sense if I can't use them. I am very new to the gaming console scene, so any help would be great.
