  • Patent number: 10007429
    Abstract: Database performance may be improved by creating additional backups from an existing backup, rather than the original database or audit log source. A second backup may be created from a first backup by copying the files from the first backup to the second backup. The replication from a first backup to a second backup with modification of the file history information allows identical backups to exist on different types of storage devices, including virtual storage devices. Continue functionality may be implemented during a move function to restart replication at a new starting point while retaining the existing move set. Tape-type-override functionality may be implemented during the replication to replace the tape type for the backups with another compatible type while retaining the original type for history file entries, tape trailers, and messages.

  • Patent number: 9946740
    Abstract: A solution for maintaining the operation of a server and allowing the transfer of data from client devices to a database without locking the database during an audit and pack process is realized that reduces the amount of time lost due to backup file storage transfer. When a file is backed up to a first storage trail through the audit process, the trail may eventually become filled to capacity. Upon the first storage trail filling to capacity, a pack process is initiated, and a backup storage trail is created to store the data during this process. Upon completion of the pack process, the data from the backup storage trail is transferred to another active storage trail.

  • Patent number: 9912750
    Abstract: A method and apparatus for high-speed data path selection for network transfer using IP addresses is disclosed. The method may include configuring an IP address for a non-RDMA data transfer or an RDMA high speed data transfer. An application executing in an emulated environment may transfer data using the same function calls for both non-RDMA data transfer or an RDMA high speed data transfer. This reduces changes to the application to allow RDMA transfers. A non-emulated interface determines whether the IP address is flagged as an RDMA address. If so, the data is transferred via an RDMA data path. If the IP address is not flagged as an RDMA address, the data is transferred via a non-RDMA data path through a traditional network stack.

  • Publication number: 20170344739
    Abstract: Virtual machines in a network may be isolated by encrypting transmissions between the virtual machines with keys possessed only by an intended recipient. Within a network, the virtual machines may be logically organized into a number of community-of-interest (COI) groups. Each COI may use an encryption key to secure communications within the COI, such that only other virtual machines in the COI may decrypt the message. Remote devices may gain access to virtual machines in a network through a virtual device relay. The virtual device relay receives data from the remote device, such as a tablet or cellular phone, and forwards the data to one of the virtual machines, when the virtual device relay shares a COI with the destination virtual machine.

  • Patent number: 9825764
    Abstract: Systems and methods for enhanced security of media are provided. Media security may be enhanced by improving the setup of encryption and/or decryption, by improving the performance of encryption and/or decryption, or by improving both. The calls related to enhanced security of media from an application in an emulated environment to a security module in the operating system hosting the emulated environment may be combined to reduce the overhead of accessing a security module. An application handling secure shell (SSH) communications may execute multiple calls to a cryptographic module in the host operating system. Because many calls to the cryptographic module during SSH communications follow patterns, two or more related calls may be combined into a single combined call to the cryptographic module. For example, a call to generate a server-to-client key and a call to generate a client-to-server key may be combined into a single call.
