This article describes that cause and possible solutions for the error Final error (-8 Not enough storage is available to process this command.)
- This error code is an official Microsoft System Error Code for "Not enough memory."
- Typically this error occurs when there is not enough free space on the protected drive to run a backup.
- For Windows Server 2008, it can also be caused by Microsoft Hotfix KB976494 not being installed.
If you have not done so already, follow the preliminary steps in the Start Here article.
Check the available space of each protected volume. Datto recommends maintaining at least 30% free space per protected volume. A minimum of 20% free space per protected volume must be available at all times on the production machine.
0 – 70%
Utilization is good.
71 – 80%
Utilization is outside optimal limits. Monitor the volume growth and look at cleaning up unnecessary files and moving non-essential data to other storage.
81 – 100%
Volume is becoming critical. Snapshots will start to fail, disk queue lengths will increase. Create space.
- For Windows Server 2008, also ensure that Microsoft Hotfix KB976494 is installed. Installing this hotfix will require a reboot of the production machine.
