It is a good start to back system files up in computer maintenance. However, you cannot create a system image backup sometimes due to lots of factors. For instance, backing up system to USB flash drive via Windows backup utility is unavailable because it will alert you “the drive is not a valid backup location”. Back to the topic, some Windows 8 users report that after upgrading to Windows 8.1, they cannot successfully create a system image using Windows built-in image tool. An error message reads “The backup failed. There is not enough space to create the volume shadow copy on the storage location. … (0x80780119)” pops up and ends up the backup process.

If it is true that the destination device is out of space, backing up system to larger storage will solve this issue. Nevertheless, most users find that the said storage location actually has plenty of free space for storing. How come?

If this won’t work, it must be the problem of “minimum required disk space for shadow copy creation”. Shadow copy in Windows backup utility will definitely take up some space, so check if all select-to-backup volumes have enough free space. Normally, if the volume is less than 500MB, the minimum free space required shadow copy creation is 50MB. If the volume is more than 500MB, the minimum free space is 320MB. And in most cases, it would be the Recovery partition that does not have 50MB free space.

To solve this problem, you need to enlarge the Recovery partition first using third party partitioning software say AOMEI Partition Assistant and run the system image backup. Launch said software, shrink any partition that has redundant space to generate unallocated space and then merge it via “Merge Partitions” feature to enlarge Recovery partition.
