Acronis SharePoint Explorer: Extraction to functioning site or in SharePoint content migration package format fails with "Failed to create package file" or with empty message.

Symptoms

You start extracting SharePoint items in SharePoint Content Migration Package format or to the functioning site. The operation fails with error message "Failed to create package file" or with empty message:

Cause

When you extract data in SharePoint Content Migration Package format, Agent extracts it to a temporary folder local to Agent machine. If there is not enough space on the target disk, the operation fails with error message "Failed to create package file" of SharePoint API.

When you extract data to functioning site, Acronis SharePoint Explorer creates a temporary CMP file first, and then it imports the CMP file to the target site. If there is not enough space for SharePoint data during import operation, the error message is empty.

There is no way in SharePoint API to detect the target CMP file size before the operation is completed.

Solution

To fix this issue, you need to increase the free hard disk space on the Web front end machine where Acronis SharePoint Explorer Agent is installed.
