Steven Cash is a lawyer for Datto, Inc., the company that has been backing up the data on Clinton’s private server. They have been subcontracted to do this by Platte River Networks (PRN), the company managing the server. Cash emails an unnamed FBI agent, informing him of several issues to be aware of prior to a conference call planned for later that day.

A Datto hard drive, the Datto SIRIS S2000, has been attached to Clinton’s server since June 2013. Cash says that Datto technical experts have reviewed administrative files and discovered through the device’s Internet interface that a series of deletions took place on the device on March 31, 2015, between 11:27 a.m. and 12:41 a.m. The data had a date range from January 28, 2015 to March 24, 2015.

Furthermore, a much greater amount of data had been “deleted automatically based on the local device’s then-configured pruning parameters.” Cash writes that “These manual requests were requested from the Local Device’s web interface for the [redacted] agent…” (US Congress, 9/12/2016) While it is possible a person’s is in the redacted space, it could also be something such as “PRN employee.”

In a May 2016 FBI interview, PRN employee Paul Combetta will confess to deleting all of Clinton’s emails on her server as well as the Datto back-up device in precisely this time period, between March 25, 2015 and March 31, 2015. It is not known if the FBI knew of the deletions prior to this letter from Datto. However, the letter certainly makes it clear, but this will not become public knowledge until an FBI report released in September 2016, almost one year later.
