Cause
By default, the Restore Security Attributes option is enabled. While trying to open a file on the network share to modify security attributes, an 'access denied' error occurs. In that case, Acronis software opens the file without restoring security attributes. As a result, a warning is produced stating that security attributes were not restored.
Solution
To avoid warnings restore without enabling the Restore Security Attributes option.
