Technology Overview New Features Backupedge
Technology Overview - BackupEDGE™ Introduction to the New Features in BackupEDGE 3.x Technology Overview BackupEDGE has a long history of providing reliable data protection for New Features many thousands of users. As operating systems, storage devices and BackupEDGE 3.x usage needs and tendencies have changed over the years, it has continuously met the challenge of providing inexpensive, stable backup and disaster recovery on a variety of UNIX and Linux platforms. Clients routinely find new and clever ways to utilize products. Storage devices have taken on new and exciting features, and incredible capacities. Products designed years ago had built-in limits that were thought to be beyond comprehension. Today, these limits are routinely exceeded. The need for data security is even more apparent. We’re constantly asking our To continue to meet the evolving needs of our clients, we are always clients what tools our asking what features of our products they find most useful, what products need to serve them improvements we can make, and what new requirements they have. better. We’ve used this knowledge to map out new product strategies designed to anticipate the needs of the next generation of users, systems and storage products. This has resulted in the creation of BackupEDGE 3.x, with a combination of internal improvements, new features and enhanced infrastructure designed to become the backbone of a new generation of storage software. Summary of Major Changes and Additions BackupEDGE 3.x features include: • Improvements to partition sizing, UEFI table cleanup after DR, and SharpDrive debugging (03.04.01 build 3). • Support for Rocky Linux 8.4 and AlmaLinux 8.4 (03.04.01 build 2). -

Running the Fermi Science Tools on Windows Thomas E. Stephens (Innovim/GSFC) and the Fermi Science Support Center Team fermi.gsfc.nasa.gov/ssc Abstract Introduction The Fermi Science Tools, publicly released software for performing analysis on science data from The Fermi Science Tools, now distributed as the FermiTools (see poster P4.3) are developed collaboratively between the Fermi instrument teams and the Fermi Science Support Center (FSSC). Development of these tools began before the Fermi Gamma-ray Space Telescope, have been available and supported on Linux and Mac launch and the tools have been available since the very first public data release in 2009. since launch. Running the tools on a Windows based host has always required a virtual machine For a time, the Fermi Large Area Telescope (LAT) collaboration, maintained a natively compiled version of the tools for running Linux. New technologies, such as Docker and the Windows Subsystem for Linux has Windows, this version regularly had issues and was never publicly released or supported. It was discontinued, even made it possible to use these tools in a more native like environment. for use within the LAT collaboration, in 2014. In this poster we look at three different ways to run the Fermi Science Tools on Windows: via a VM, While it has always been possible to run the tools on Windows using a virtual machine with a Linux guest operating system, this is a somewhat “heavy” solution. With the recent development of both Docker and the Windows Subsystem a Docker container, and using the Windows Subsystem for Linux. -

OS family Unix-like (based on Red Hat Linux) Working state Current [1] Source model Free and open source software (with exceptions) [2] Initial release 2003-11-16 It was codenamed Yarrow. Fedora Core 1 was based on Red Hat Linux 9 and shipped with version 2.4.19 [3] of the Linux kernel, version 2.4 of the GNOME desktop environment, and K Desktop Environment 3.1. Latest stable release 17 (Beefy Miracle) / May 29, 2012 Available language(s) Multilingual Update method Yum (PackageKit) Package manager RPM Package Manager Supported platforms i686, x86-64 Kernel type Monolithic (Linux) Userland GNU Default user interface GNOME 3 [1] License Various free software licenses, plus proprietary binary blobs. Official website [4] www.fedoraproject.org Fedora ( /fɪˈdɒr.ə/), formerly Fedora Core, is an RPM-based, general purpose collection of software, including an operating system based on the Linux kernel, developed by the community-supported Fedora Project and sponsored by Red Hat. Fedora’s flexibility makes it capable of serving as a digital repository for a variety of use cases. The Fedora Project's mission is to lead the advancement of free and open source software and content as a collaborative community.[5] One of Fedora's main objectives is not only to contain software distributed under a free and open source license, but also to be on the leading edge of such technologies.[6][7] Fedora developers prefer to make upstream changes instead of applying fixes specifically for Fedora—this ensures that their updates are available to all Linux distributions.[8] Compared to more mainstream non-Linux operating systems, Fedora has a short life cycle.
