About encrypted saves:
they are untouched and you can restore them as is, ie no need to start the game.
About region change option:
Most games use the same save "structure" for any region, but not all.
Region change is 100% safe and reversible, unless i/o errors occur
If the save does not work, the game uses a slightly different save structure (or your entered ID is wrong).
About orphan saves:
Saves of games that are not installed in your system.
You can backup and restore them. (For eg. games that require a save of the predecessor to unlock stuff)
