An apparatus and method for securing a baseline backup are disclosed. As part of an incremental backup process, a selected set of file system data, including directories and files, are identified. The selected set of file system data are compressed, and then encrypted. Based on the encrypted and compressed file system data, a data digest is generated that uniquely identifies the encrypted and compressed file system data. The compressed and encrypted file system data are written to a portable storage device along with the data digest, thereby enabling the safe, manual transport of the file system data to a secondary, or backup, computer system (e.g., at a remote data center).
