Windows Backup with Exchange 2010 - Incremental vs. Full Backup

Hello Everyone,

I am using Windows Server Backup on Server 2008 R2 with Exchange Server 2010. I have it set to backup a few times per day going to a network drive. In the settings I selected the C Drive, D Drive, System State and Bare Metal Recovery and made sure that it did a full VSS copy.

After the backup completes, it still says that it was an "Incremental Backup" and not a full backup. I am just wanting to make sure that the log files are there, etc... I did go under the "Configure Performance Settings" on the right side and made sure that all of the selected items were set to "Full Backup."

I know that when you copy to an external remote/network drive, it does overwrite the previous copy that was there. Perhaps it is updating the necessary information and only adding the files it needs compared to a whole new backup?

I think I remember reading about this issue previously.  In order to get it to do the Full backup you need to remove the previous backup or else it does incremental to keep it up to date.

Microsoft only mentions this:
"Faster backup technology. Windows Server Backup uses Volume Shadow Copy Service (VSS) and block-level backup technology to back up and recover your operating system, files and folders, and volumes. After the first full backup is created, you can configure Windows Server Backup to automatically run incremental backups by saving only the data that has changed since the last backup. Even if you choose to always perform full backups, your backup will take less time than it did in earlier versions of Windows."

Which doesn't really state how they made the full backups faster.  Probably because it only does incrementals once a full backup is completed.

I will look into this.

Considering that it is only adding the changed files, I am wondering if the log files would transfer over and if all the information required is there or not.

Thoughts on that aspect?
I wouldn't rely of native windows server backup, it's pretty bad.

Backup and recover physical and cloud-based servers and workstations, as well as endpoint devices that belong to remote users. Avoid downtime and data loss quickly and easily for Windows-based physical or public cloud-based workloads!

Radweld: what are your objections to Windows Server Backup?  I've been using and recommending it with pretty good success, including a couple of successful bare metal restores.  My only serious objection so far is that you can't restore to a smaller hard drive.  Other than that, I've been pleased with it.  If there are potential problems I may encounter, I'd like to know about them.
Well for one the problem originally posted, 2 the only way to obtain a good backup of most workloads is to backup the entire system. This is wasteful. Dpm leverages native wsb but at least it adds a usable front end to it.

Radweld - In this instance, what would you suggest if the server blows up? I have Genie9 Backup Software and they have an option to do a disaster recovery option... I don't know if you are familiar with it but I will try it on a new server we got and let you know.

In the current instance, how do I know the log files are being backed up, etc?

Wsb is ok for a single point in time backup but it's wasteful as you have to backup the entire server. You really only want the system state a bits of exchange line the databases. You can quickly rebuild a failed server using setup /recoverserver and use database portability to remount the database. I have not used that backup software but if it's exchange aware then it should be ok.

To check key database metrics review this blog, there is a nice powershell script that checks values line lastbacked up etc.

Thanks! I will be sure to check it out. Otherwise, not sure why it is doing what's it is doing?
