I have a network of about 50 users who are very email intensive. They generate approx 50-90GB of emails a month. They split the load in several PSTs to avoid damage. The problem is I would like to backup those emails over to a File Server.
The problem is that since all emails reside in psts even if the users just receive or place 1 new email in the PST, it's a completely 'new' file so when the next backup occurs the entire file needs to be copied all over again.
Of course this causes a major strain on the network when the users starts backing up their emails. Is there a software or method to backup the files at bit level instead of the entire file?
These users are using Outlook 2007/2010. I am not using Exchange and there is no way it will be introduced unfortunately. The file server is running Windows 2008.
I hope I made myself clear and thanks for reading. Cheers
