Consider PS3 as a partially deffective product
Is it possible to do backups in an exterior storage?
Yeah there is a "backup utility" on the PS3 that allows you to backup the contents of your PS3's HD to an external device. I do a backup about once a month to avoid the OP's problem. Also if your PS3 does get shut off in the middle of a game & a screen that says your file system may be corrupted shows up when you restart it just press the circle button & your PS3 will start as normal. You do not have to reformat your HD if you get that screen. More than likely there is no corrupted data cause that screen is just a safety cache. Any corrupted data can be removed by just deleting the offending save or game data from the XMB anyways. The only thing it will effect is the game or save itself, not the PS3 as a whole.
