Windows Server 2008 R2 101 Mb system partion full, backups failing

We have one VM that the system reserved partition (101 MB) is full which is causing any backup that includes system state to fail.

I have seen the discussions that say you can just delete that if you are NOT using Bit-Locker, but that is not true. The system reserved partition (when installing Windows Server OS if you do NOT delete it at the time of partition configuration) contains boot mgr files and CAN NOT BE DELTED.

Any help is appreciated.

Last time we had an issue like that was vss not allowing backup due to free space in that case a 500mb partition so vss wanted 320mb free so was able to shrink partition under 500mb then vss only wanted 50mb free.

Is that partition full or just has under 50mb free, on phone at moment but if you search for vss free space system partition I found detailed document with some suggested methods before, easiest might be to mount that virtual drive in another os and shuffle positions around to make that volume bigger.

Have you tried the following?


1) Open a command prompt with administrator privileges (right click => run as administrator)

Type:

bcdboot c:\windows /s c:

You should get a message similar to:

Boot files successfully created.

2) Open the Disk Management GUI (you could use diskpart for scripts), locate the C:\ partition right-click and select “Mark Partition as Active”, select yes to the “do you want to continue message”

3) Reboot to confirm that everything is ok.

4) In Disk Management you can now delete the 100Mb System Reserved partition by right clicking on it and selecting “Delete volume”

Before I got the information above, this is how I did it.
This is more usefull if you have already deleted the System Reserved partition or messed it up some how and now need to delete it from the recovery console.

1. From Disk Management assign a drive letter to the System Reserved Partition so that you can access the files. They are hidden, so you will need to turn off the option to hide system files.
2. Copy bootsec.bak, bootmgr and the entire boot folder from the System Reserved partition to the c:\ drive.
3. Set the c:\ drive partition as active
4. Now you can delete the System Reserved Partition. I had to go recreate my RAID array after rebooting to the RAID BIOS to delete it. You might also be able to delete it using BartPE or WinPE.
5. Boot the OS from the installation DVD and choose repair.
6. Load RAID drivers if you need to and then go to the command prompt.
7. Run these commands to fix the MBR and boot sector.
bootrec.exe /fixmbr
bootrec.exe /fixboot
bootrec.exe /rebuildbcd
8. Reboot!

The MSR partition should not be filled up. Find out if some system restore points or vss snapshots have been saved into it.

Well, as I said - find out what is filling that partition.
Good, yes this was the document I was referring to in my first post but was in middle of Wales on 2G mobile signal at the time so just suggested what to search for.

This turned out to be the problem. No other suggested solutions involved this.
