AMETHYST archives to a Windows Share.
If you install Google Drive and setup a Windows Share in the folder, you use the Windows share details to configure AMETHYST as per normal Windows Share archiving.
Once the archive is done to the Windows Share, Google Drive will handle it.
NOTE:
1.) Make sure that your Google Drive setup is as per Company requirements to keep recordings available after archived and purged from AMETHYST.
2.) Once purged from AMETHYST Google Drive has the only version of the recordings.
