Win 2003 server running Exchange 2003. Backup is taken with Backup Exec.
The company is quite small. so a full backup of Exchange is just around 11 GB in size.
I need, on a regular basis, to send the backup files to a remote location, using a slow ADSL-internet connection (around 1 MBit upload). Let say I will send the backup files every sunday. 11 GB with 1 MBit takes 30-35 hours, not acceptable.
So, my plan is to start with one full backup, and sending it to the remote location.
I then use the differential backup method in Backup Exec to create smaller files which will make it possible to send theese wuite small backup files maybe every night.
I simply wonder how long I can do this (of course the differential backup will grow over time, but that is no problem), before I have to take a new full backup.
My concern is that I have never really restored a complete Exchange server using a full backup together with latest differential one. What is your opinion?
