BDBB can be used to move you client data to your new server. Can I ask you what you were using for a server before and what the new server is? Alex the creator of BDBB actually moved the drives from one server and EX47x to an EX49x and performed a server recovery. Now he was much braver then I was in doing this. I chose to copy my data between the two servers and then move the drives as I freed up the storage space on the older server. The only thing I didn't do was move the client data which I could of with BDBB because I chose to let the older clients continue to use the original server to be used for backups and some misc other things thus providing me with ample capacity to back up more clients both mine and those I work on for others.
Anyway this is what Alex wrote about migrating his drives from one server to another as mentioned above just click on the link below:http://www.mediasmartserver.net/2010/01 ... me-server/
Please review the article carefully to see if this may be of interest to you. Also if you do not have your data backed up then now is the time to back up what is most important to you. While you data is safe on your server is something bad were to happen to it say a flood or fire then your data would be lost if you do not have it backed up. This is just good practice for all to follow.
As for BDBB its a wonderful Add-In and I am happy to see you are using it. I use an external drive for my BDBB backups so I can keep them in a safe location if I desire. I also copy the BDBB Backups from one server to be archived on another as a redundant backup. Where it really shines is when something goes totally wrong with your Client Data and BDBB restores that client data very well. I have used it once in the past and it saved me big time because some of the clients have in backup are not on site so to lose those backups would be a nightmare. That client is so important it has its running drive and I have made 2 other copies of the drive one is with the client and the other is here but even with that level of protection BDBB is my first line of defense.
The point here is Backups are important and while the server is a great tool for Backups it should not be your only tool.
