Heinrich du Toit wrote: In auto save documentation it says "Autosave is not completely bulletproof" and that at APS you have problems at times. Not restore. Most of the data I have is for the version of autosave in synApps 4.6. For that version, problems include failure to save parameter values because the save task crashed, the task had a stale file handle, one save operation took long enough to overlap with the next save operation, or unknown causes. I don't have any record of a released version of autosave restoring corrupted data, or causing some other problem in an ioc. It's all about failure to restore parameter values, and this is nearly always caused by an earlier failure to save them. For recent versions of autosave, I have so far two instances of failure to save parameter values, and complaints about unwarranted error messages. There is more version-specific information on the autosave web page, and in release notes: www.aps.anl.gov/aod/bcda/synApps/autosave/autosave.html
