I know that Autosave is generally used for automatically saving the values of a set of database records and restoring them at boot time, but I'd like to save a small set of values on command, and then be able to restore them on command.

I have found the create_triggered_set() function that I can run in the ioc startup script that assigns a database PV to trigger a save, and that seems to be a step in the right direction for what I want to do.

However, a couple of problems:
1) There seems to be no corresponding  function to assign a PV to trigger a restore.  I suppose I can get around that by using a subroutine record to call fdbrestore() when it is processed.
2) Even if I can get around issue 1), when I run create_triggered_set() in the startup script at boot time, it clobbers the existing saveset. Is there a way around this?

Perhaps I'm trying to use the wrong tool? Is there a better one for what I want to do?
