Backupassist and Windows Server 2012 BackupAssist and Windows Server 2012 BackupAssist v7.1 and later, in a Windows Server 2012 environment. BackupAssist 7.1 & Windows Server 2012 Windows Server 2012 introduces new technologies and features that can affect how BackupAssist operates. This resource explains how some of the key changes impact BackupAssist and what you need to know when performing backups and restores in a Windows 2012 environment. Resilient Files System (ReFS) ReFS is a new file system that introduces reliability and compatibility features to Windows Server. BackupAssist supports ReFS formatted drives as a backup source and destination for all backup types. BackupAssist can also restore from ReFS formatted drives. Considerations: File Protection backups cannot use single-instance store when the backup is saved on a ReFS formatted destination. This means all of the data will be backed up each time the backup job runs. System Protection cannot incrementally back up data from a ReFS formatted drive (source). This means a full backup of all selections will take place each time the backup job runs. De-duplication De-duplication for Windows Server 2012 is a technology that efficiently stores and transfers data using less space. All BackupAssist backups can operate in a de-duplicated environment. Considerations: BackupAssist will backup files from a de-duplicated volume in the non-optimized mode. Therefore, the backup will not retain the de-duplicated format. Server Message Block Server Message Block (SMB) is a network protocol for sharing resources. SMB 3.0 includes changes such as improved performance and VSS support. BackupAssist supports SMB 3.0 as both a backup source and destination. This includes backing up data from a CSV source to an SMB destination. Considerations: Historical information is not retained for System Protection (image) backups on SMB volumes. When an SMB 3.0 share is the backup destination, full backups will take place and only a single restore point will be available. However, the Data Container option for System Protection backups enables backup history support and can be used in a SMB environment. To backup up or restore to an SMB file share the client and server must be running a SMB 3.0 capable operating system, and the SMB file share must have the File Share Copy Agent enabled (via the file server role service). BackupAssist System Protection jobs do not support backing up Hyper-V over a SMB 3.0 guest (that is, Hyper-V guests stored on SMB 3.0 file shares). File Protection jobs or File Archiving jobs should be used to back up this type of Hyper-V guest. File Protection and File Archiving backups and restores are supported for Hyper-V over SMB 3.0. BackupAssist 7.1 and Windows Server 2012 1 © Cortex I.T. 2001-2014 Resource: Version Jul 11 2013 Storage spaces Windows Server storage spaces are virtual disks created from pools of real disks. BackupAssist supports Windows Server storage spaces as a data source and destination for all backup types. BackupAssist can also restore data from Windows storage spaces. Considerations: We support Mirroring and Parity modes. Failover cluster and CSV Windows Server 2012 introduces the CSVFS format, which allows a cluster to differentiate CSV storage from other NTFS storage. BackupAssist supports backing up Hyper-V guests located on CSV storage using the CSVFS file system. Considerations: BackupAssist supports SMB 3.0 servers as a CSVFS backup destination. Bit Locker drive encryption is not supported. BackupAssist does not support backups of files from both CSVFS and NTFS locations in the same snapshot. For example, it is not possible to back up a Hyper-V guest with a source in a CSV along with another guest that is on an NTFS volume. Hyper-V Hyper-V is Microsoft’s implementation of virtual machine (VM) technology. Virtual machines run on a physical host machine and provide dedicated operating system environments. Considerations: Hyper-V Replica: Hype-V Replica enables replication of a virtual machine across the internet. BackupAssist supports Hyper-V Replica and can back up and restore a primary Hyper-V guest using any backup type. CSV Environments: CSV backups are supported by the System Protection backup type, but CSVFS and NTFS file systems cannot be mixed (as described above).

  • Softnas Deployment Guide for High- Performance SQL Storage
    SoftNAS Deployment Guide for High- Performance SQL Storage Introduction SoftNAS cloud NAS systems are based on an innovative, memory-centric storage architecture that delivers unparalleled NAS performance, efficiency, and value. They incorporate a hybrid disk storage technology that tailors the usage of data disks, log solid- state cache drives (SSDs), and read cache SSDs to the data share's specific needs. Additional features include variable storage record size, data compression, and multiple connectivity options. As a Cloud NAS solution, SoftNAS cloud NAS systems provide an excellent base for Microsoft Windows Server deployments by providing iSCSI or Fibre Channel block storage for Microsoft SQL Server, and network file system (NFS) or server message block (SMB) file storage for Microsoft Windows client access. This document covers the best practices to follow when deploying Microsoft SQL Server on a SoftNAS cloud NAS system. The intended audience is storage administrators and Microsoft SQL Server database administrators. Maintaining High Availability As with any business-critical application, high availability is a crucial design criterion to be considered when deploying a Microsoft SQL Server installation. Microsoft SQL Server 2016 can be installed on local and/or shared file systems, and SoftNAS cloud NAS systems can satisfy both of these options. Local file systems (from the Microsoft Windows Server perspective) are hosted as block volumes—iSCSI and/or Fibre-Channel-connected LUNs and file systems as SMB and/or NFS volumes. High availability starts with the network connectivity supporting the storage and server interconnectivity. Any design for the storage infrastructure should avoid single points of failure. Because many white papers and publications cover storage-area networking and network-attached storage resilience, those topics are not covered in detail in this paper.

  • File Systems
    File Systems Profs. Bracy and Van Renesse based on slides by Prof. Sirer Storing Information • Applications could store information in the process address space • Why is this a bad idea? – Size is limited to size of virtual address space – The data is lost when the application terminates • Even when computer doesn’t crash! – Multiple process might want to access the same data File Systems • 3 criteria for long-term information storage: 1. Able to store very large amount of information 2. Information must survive the processes using it 3. Provide concurrent access to multiple processes • Solution: – Store information on disks in units called files – Files are persistent, only owner can delete it – Files are managed by the OS File Systems: How the OS manages files! File Naming • Motivation: Files abstract information stored on disk – You do not need to remember block, sector, … – We have human readable names • How does it work? – Process creates a file, and gives it a name • Other processes can access the file by that name – Naming conventions are OS dependent • Usually names as long as 255 characters is allowed • Windows names not case sensitive, UNIX family is File Extensions • Name divided into 2 parts: Name+Extension • On UNIX, extensions are not enforced by OS – Some applications might insist upon them • Think: .c, .h, .o, .s, etc. for C compiler • Windows attaches meaning to extensions – Tries to associate applications to file extensions File Access • Sequential access – read all bytes/records from the beginning – particularly convenient for magnetic tape • Random access – bytes/records read in any order – essential for database systems File Attributes • File-specific info maintained by the OS – File size, modification date, creation time, etc.

    NAP-3 Microsoft SMB Troubleshooting Rolf Leutert, Leutert NetServices, Switzerland © Leutert NetServices 2013 www.wireshark.ch Server Message Block (SMB) Protokoll SMB History Server Message Block (SMB) is Microsoft's client-server protocol and is most commonly used in networked environments where Windows® operating systems are in place. Invented by IBM in 1983, SMB has become Microsoft’s core protocol for shared services like files, printers etc. Initially SMB was running on top of non routable NetBIOS/NetBEUI API and was designed to work in small to medium size workgroups. 1996 Microsoft renamed SMB to Common Internet File System (CIFS) and added more features like larger file sizes, Windows RPC, the NT domain service and many more. Samba is the open source SMB/CIFS implementation for Unix and Linux systems 2 © Leutert NetServices 2013 www.wireshark.ch Server Message Block (SMB) Protokoll SMB over TCP/UDP/IP SMB over NetBIOS over UDP/TCP SMB / NetBIOS was made routable by running Application over TCP/IP (NBT) using encapsulation over 137/138 139 TCP/UDP-Ports 137–139 .. Port 137 = NetBIOS Name Service (NS) Port 138 = NetBIOS Datagram Service (DGM) Port 139 = NetBIOS Session Service (SS) Data Link Ethernet, WLAN etc. Since Windows 2000, SMB runs, by default, with a thin layer, the NBT's Session Service, on SMB “naked” over TCP top of TCP-Port 445.
