A.D.: But do they guarantee completely consistent backups? Anyone can backup files in a running mdb -- but how can you be sure there are no update/delete locks, or pending/reversing transactions in place? Microsoft emphatically states that you can't rely on the internal consistency of the data when you do a live backup of an mdb file - regardless of whether you backup whole files, or tables individually. Honestly, I'd love to be able do live backups of Access data, but until I see proof that they handle these data consistency issues properly, I'll hold off. After all, a restore that scrambles the owner's data is of no use to anyone. I'll end by restating my current position: Access is not an enterprise data server. If you need 24/7 access, high concurrency, failover/data recovery, and live backups, move to SQL Server or the like. -Ken -----Original Message----- From: A.D.Tejpal [mailto:adtp at touchtelindia.net] Sent: Tuesday, December 09, 2003 10:27 AM To: Access Developers discussion and problem solving Subject: Re: [AccessD] Backing Up Access MDB Paul, You might like to take a look at Access Add-In named SelfSaveAddIn.mda available at Rogers Access Library (Other Developers Section). Once installed, you can create compacted backup copies from within the running db at the click of a button (without having to close it first). If it happens to be a split db, compacted backup copy of the back end also gets created simultaneously. Following options are available for stamping the backup copies (over & above the basic suffix of "_Bk") - (a) Current date and hour (b) Current date (c) No stamp Regards, A.D.Tejpal -------------- ----- Original Message ----- From: Dan Waters To: 'Access Developers discussion and problem solving' Sent: Tuesday, December 09, 2003 21:09 Subject: RE: [AccessD] Backing Up Access MDB Paul, If you only need to back up the data, perhaps you could just manually copy the data tables from the operating mdb to a different mdb? What I've done before is to time my mdb changes (or backup) during lunch when most people are out of the system, and won't mind if you log them out.

Is there a way to backup the mdb file without taking users out, without the risk of losing any data ?
