In Paragon 17.20.0 Backup Options is the option to Run External Programs/Scripts Before/After backup. There is a checkbox labeled Run Asynchronously. What exactly does this mean? It appears that synchronously means that both the backup and the external program exit at the same time. My question is due to the fact that my external batch file which tries to copy the files produced by the recent backup encounters the message that the file is being used by another program. I want my batch file to run only after Paragon has unlocked the recent backup files, even after the optional validation process.
