Resuming failed backup


Recommended Posts

Posted

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.

Having a backup job that takes 36 hours is unacceptable

for two reasons:

a) As you say, the chances of it failing are high.

b) It could take up to 36 hours to retrieve a file.

 

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.

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.

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.
