Do you have a privacy guarantee?

There is EULA - http://dl.acronis.com/u/pdf/Acronis_corporate_EULA_en-US.pdf
and a quote from it -
Acronis will not decrypt your files unless (a) it reasonably believes that it must do so to troubleshoot problems with the Software or Services; or (b) it reasonably believes it must do so in order to comply with any law, subpoena, warrant, order, or regulation. Acronis may also provide access to your data to government authorities if Acronis suspects or believes that the data contains child pornography or
other prohibited content or data or that the Data is being used for illegal purposes. You acknowledge that Acronis or Acronis affiliates may use servers and other equipment to provide the Software or Services that are located in the United States or in other countries where litigants, law enforcement, courts, and other agencies of the government may have the right to access data stored within their jurisdictions upon terms and conditions provided by local law, and that, as a result, they may gain access to your backup data as provided by applicable local law.

It doesn't state that you'll be informed about it, though.
