Guest Ben Posted September 18, 2007 Posted September 18, 2007 I am using Windows Backup (NTbackup.exe) to backup 1TB of files to a network drive. Because it takes 36 hours for this to complete, the chance of it failing is high. Can I resume a failed backup (without resorting to a subsequent differential backup)? Is robocopy a better solution for what I'm doing? My concern is with with "in use" files, (ie. a PST files was causing Robocopy to stop, retry, stop retry endlessly). What is your recommendation, besides using a third party tool. Your help is greatly appreciated. -Ben

I would prefer robocopy any time. It would let you retrieve files instantly. You should invoke it inside a batch file and precede it with a command that checks if Outlook is active or not. Note that robocopy has a switch that sets the number of retries. Note that robocopy won't back up the System State. You can still use ntbackup for this part of the job.
Guest Ben Posted September 19, 2007 Posted September 19, 2007 Re: Resuming failed backup Pegasus, Thank you for that answer, it is exactly what I wanted to hear. I am now using Robocopy for file backups (with switches to accomidate "in use" files) I am using NTBackup.exe to make an ASR for system state. -Ben "Pegasus (MVP)" <I.can@fly.com> wrote in message news:uZrVnYh%23HHA.4432@TK2MSFTNGP02.phx.gbl... > > "Ben" <Ben@discussions.microsoft.com> wrote in message > news:673984AC-2BBB-42DA-8A59-3D63F91012E9@microsoft.com... >>I am using Windows Backup (NTbackup.exe) to backup 1TB of files to a >>network >> drive.

Guest Pegasus \(MVP\) Posted September 19, 2007 Posted September 19, 2007 Re: Resuming failed backup Thanks for the feedback. If you want to do a really fine job then you could put the robocopy command inside a batch file, followed by a few more lines of code that extract the summary and send it to you automatically by EMail.
