Why Windows Backup Not Enough Space for Shadow Copy

When reading the issue carefully, you will find this error code 0x80780119 is because of no enough disk space on the storage location of the volume shadow copy. Generally speaking, the volume shadow copy means a technology called Volume Shadow Copy Service which allows creating backup files or snapshots for computer files or volumes. In fact, create system image failed not enough disk space issue is related to the disk space on the source disk, especially system reserved partition and recovery partition. If the volume is less than 500 MB, the minimum free space should be 50MB. On the other hand, if the volume is more than 50MB, the minimum should be 320MB of free space. For more than 1GB volume, at least 1GB of free space should be required. If you get Windows backup not enough space for shadow copy error, your source drive probably can’t meet these requirements.

As you know, Windows NTFS file system maintains a particular record called USN which records the changes to the volume. When a change is made to a file or directory, the USN Change Journal also updates with the description of the change. However, the Change Journal will be created on the system reserved partition if a fault appears during the process of doing some disk or file operations, which takes much disk space.

Just right click the system reserved partition and select “Properties” to check whether free space meets the requirements. From the following picture, the free space is less than 50MB.


In this case, the important thing should be to clear USN Journal Files. Here are the detailed steps:

Step 1: Firstly, please assign a drive letter for system reserved partition with Windows Disk Management “Change Drive Letter and Paths”.

Step 2: Then run CMD as administrator.

Step 3: Type the following commands in turn:

fsutil usn query journal X:

“fsutil usn deletejournal /N /D E:”

Here E refers to the drive letter of system reserved partition. After that, remove this drive letter.

Step 3: Finally, hit “Apply” to execute this change to the selected partition.

Solution 3: Change Recovery Partition Size

Usually, in Windows 8, recovery partition is the main factor to Windows backup failed not enough disk space issue. Here take recovery partition 900MB as an example. If you want to create a system image successfully, the minimum free space should be 320MB. Please check its free space. If it is less than 320MB, MiniTool Partition Wizard also can help you to change recovery partition size with “Extend Partition” feature.
