SBS 2011 can't perform full backup
Have recently installed SBS 2011. When i tried to run a full backup got an error that there was not enough space available. After doing some research discovered that this is due to the system reserved partition 100MB only having 38MB of free space. I have Bit Defender Business AV also installed and people have said that this is one of the causes. I have tried to disable the USN Journal but it keeps enabling itself after restart. It seems as if the only way is to increase the size of the system reserved partition, bloody Microsoft. Please can some tell me how to do this other than having to purchase 3rd party software.
The 100MB partition is installed by all modern versions of windows (client and server) for bitlocker. They are always 100MB and they always have about 38MB free. DON'T mess with them. It is NOT the cause of your failing backup. Whoever told you that was misinformed. If it was, millions of machines would fail backups, since it is present on all modern installs.
By far the most common reason for the error you see is because the backup target is too small or because disk manager cannot access all the space (many 3TB drives have this issue, for example.) look there first, but leave that 100MB partition alone. It has no bearing on your problem.

The problem only seems to occur if i do a full system backup. If i choose custom backup and deselect Bare Metal Recovery, System State and System Reserved and backup only the local drives it backups up fine. This is a new install and the backup drives are 2TB and empty. Total backup size of whole server is approx. 300GB.

The message i get from Windows Backup is as follows:
Backup failed to complete. There is not enough disk space to create the volume shadow copy on the storage location. The volume shadow copy operation failed with the following error ox8004231F
In the application eventlogs i get the following:

Please review the event details for a solution, and then rerun the backup operation once the issue is resolved.

Have a similar setup at another site and am not facing these problems. Can't even backup just the system state alone.
Diskpart.exe
DISKPART > Select Volume 1
Volume 1 is the selected volume.
DISKPART > Extend Size=20000 ("20000 will expand the disk by 20GB as an example, if no size is specified all available space will be allocated to the partition") Disk Part successfully extended the volume.
