Hey -- this was a question I got though: Is there a way to make UniData VSS/Shadow-Copy 'aware'?
Does that question come up to other people as they transition users to U2? -----Original Message----- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Bill Haskett Sent: Thursday, August 09, 2012 10:06 AM To: U2 Users List Subject: Re: [U2] dbpause/dbresume or stopud/startud David: I'm sure I don't have a complete understanding of your situation. I use "dbpause" all the time and run backups using Windows backup utilities. I don't think they have a problem backing up locked files because of the volume Shadow Copy functionality built into Windows (of course the service needs to be running). Our backups have been running on a number of machines over the last seven or eight years. Am I missing something?
