When you backup files on a Windows 7 computer you may receive error 0x81000019 with an error message similar to the following:
"A shadow copy could not be created. Please check the 'VSS' and 'SPP' application event logs for more information. Details: Insufficient storage available to create either the shadow copy storage file or other shadow copy data."
This error can happen because of having too many Windows language packs installed on your computer.
The cause is that the Backup process involves the system writer that reports files in the important applications installed on the machine. In the case where a large number of language packs is installed, the metadata file reported by this writer becomes huge in size and does not fit the 100 MB volume. This causes backup to fail since there is not enough space for the shadow copy creation. This is not something that you can check on to validate since this metadata file is created during backup and deleted at the end.
To resolve the issue, uninstall all of the unused language packs that are currently installed on your computer. You can do this by clicking Start, and then typing Lpksetup.exe in the Search box and then clicking Lpksetup.exe in the list of programs. Once the Language Pack installer starts, click Uninstall display languages. Uninstall the languages that you do not use, and then restart your computer and restart the backup.
