Alan, Were they using the personal version of Mozny or the Pro version. If it is the personal one then I guess the product may not be using the shadow copy facilities which mean that locks don't have to be placed on the files to do the backup and instead uses shadowing which was in XP (just but not really stable), nearly worked in Vista (As most stuff did) and seems to be rock solid on Win 7 and Server 2008 upwards.
Acronis has the same problem but I guess that's why the pro & server versions are more expensive. Just as an aside, our Acronis perpetual backup works no problem with VFP and other programming languages data and we test that out once a month with a "pull the plug" test on live data.

Had an episode this week where a customer suddenly started getting continual file accessing errors with VFP tables and memo files, and even 'memo file is invalid' errors. Turns out they had installed MozyPro online backup on another server and just pointed it at the main server, and it had handles on loads of VFP files when they were in its backup queue. No actual file, index or memo corruption was present. FWIW, continual backup solutions are not a good fit for multi-user VFP applications. -- Alan Bourke alanpbourke (at) fastmail (dot) fm [excessive quoting removed by server] _______________________________________________ Post Messages to: ProFox@leafe.com Subscription Maintenance: http://leafe.com/mailman/listinfo/profox OT-free version of this list: http://leafe.com/mailman/listinfo/profoxtech Searchable Archive: http://leafe.com/archives/search/profox This message: http://leafe.com/archives/byMID/profox/bd031ecabf2b60499200aab3dbb4a99973637...@ex-a-fpl.fpl.LOCAL ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
