When Clinton’s first server is upgraded with a new server in March 2009, a Seagate external hard drive is attached to the server to store back-up copies of all of its data.
Bryan Pagliano, who manages the server at the time, will later tell the FBI that daily changes are backed up onto the hard drive every day, and a complete back-up is made once a week. As space on the hard drive runs out, backups are deleted on a “first in, first out” basis.
This continues until June 2011. That month, Pagliano travels from Washington, DC, where he works in the State Department, and goes to where the server is, in Chappaqua, New York. Pagliano replaces the Seagate external hard drive with a Cisco Network Attached Storage (NAS) device, also to store backups of the server.
It is unclear what becomes of either back-up device or the data they contained. The FBI’s September 2016 final report on the Clinton email investigation will only mention: “The FBI was unable to forensically determine how frequently the NAS captured backups of the Pagliano Server.” But the report will also complain about the “FBI’s inability to recover all server equipment,” and there will be no mention of any data recovered from either back-up device. (Federal Bureau of Investigation, 9/2/2016)
Also in September 2016, Justin Cooper, who helped Pagliano manage the server, will be asked about these hard drives at a Congressional hearing. He will say he only heard about them from reading the FBI final report. (He claims he handled customer service while Pagliano handled the technical aspects.)
He will also be asked if FBI agents ever came to the Clinton’s Chappaqua house to seize any equipment. Cooper worked as an aide to Bill Clinton in the house, but he will say he is unaware of the FBI ever coming to the house. (US Congress, 9/13/2016)
