3. EMC NetWorker Security, Simplicity, and Speed for Backup and Recovery

4. NetWorker Terminology • NetWorker Server – Server that maintains the databases and client file Indexes. Controls the initiation of the backup jobs • NetWorker Storage Node – Server that allows access to tape devices and used by clients to backup their data across the network. • NetWorker Client – Servers that contains the data to be backed up. • Niser (nsr) – most of the cli commands start with “nsr”, also the directory that NetWorker is installed under is “nsr”. The term “niser” is used to describe this. • Pools – This is used to identify the tapes and how they will be used • Groups – used to group like data together • Clients – identifies the data for each Client server that is to be backed up. • Datazone – Collection of a NetWorker Server, storage nodes and clients

5. Architecture of NetWorker • NetWorker is a 3-tier product. • Server • The server is the portion that maintains the NetWorker databases, Client file indexes, etc. • Performs the selection process of the devices to be used. • Passes the process to the necessary storage node client • Controls libraries and devices (tape, disk) • Storage Node • Two types – Dedicated, Standard • Dedicated - can only backup its one data • Standard – used to backup multiple clients • Controls libraries and devices (Tape, Disk) • Client • Sends the data to it’s associated storage node or to the Server

6.

13. Elements of Console Windows • Task Bar • Separate tasks user performs. Drives how the rest of screen drawn. • Menu Bar • Changes depending upon task. A “task specific” menu item will appear. This menu item can be accessed via a right-mouse click. • Tool Bar • Task specific. Some actions will behave differently depending upon the object selected in the navigation or details pane. • Navigation Pane • Classic “tree view” organization. Not all task areas have a navigation pane. • Details Pane • Where details, results or messages are displayed. Generally, the details pane consists of a table.

14. Groups Arch Reqs Devices Alerts Sessions Log Server, group & client resources Library and Device Config/Ops Navigation between Console and Admin ConsoleWindow NW AdminWindow Label TapesPoolsVolumesIndexesSaveset Query

15. Standard Console features (cont) • “Default” table columns are the ones predefined by Console (however, there is, currently, no way to “reset” back to the default set of columns) • All table columns can be sorted, reordered and resized • User preferences are saved in the Console database (therefore, they “follow” the user, not the machine) • Preferences are different for Console and Admin sessions • Online Help is screen “context” sensitive (new for Keystone) • All help content is single-sourced, i.e. printed docs and online help are the same (new for Keystone)

16. Troubleshooting: NMC Server • Review log files on Windows: C:\Program Files\Legato\Management\GST\logs on Solaris: /opt/LGTObgst/logs • Start gstd with -Dn, where n = 1 through 6 (a lot of output above 2) • Debug level can be changed from the System Options (Setup task) • Environment variables • GST_MAXLOGSIZE • GST_MAXLOGVERS • GST_DEBUG

17. Troubleshooting: Server Directories The logs directory The DB directory

18. Troubleshooting: NMC Client Enable the output of client log messages: • Open the Java Web Start Application Manager • Go to File->Preferences->Advanced • Check "Show Java Console" to display Java Console window when the client is running. • Check "Log Output" if you would like the info in a file.

19. Troubleshooting: Client Debug Level Set the debug level of the client by: • Pressing CTRL, SHIFT & right mouse button in any details pane (right side of screen) • In the menu, select required debug level • Output to Java Console (see previous slide)

36. Backup server 1 Backup server 2 Backup server 3 Tape library EMC AlphaStor server Advanced Media Management - AlphaStor • Device and library sharing • Consolidate resources • Reduce tape-library total cost of ownership • Controls resource allocation • Has the capability for queuing requests • Media lifecycle management • Track movement of tapes • Increase tape return on investment • Improve management Tapes to move offsite Tapes to return for reuse

37. AlphaStor Terminology • AlphaStor Server – Media manager, contains database of media information, controls assigning and appyling of rotation policies • LCP – Library Control. Controls the arm of the library, talks to the library to obtain inventories of tapes and controls physical movement of tape from slot to drives. Also controls the importing and exporting of tapes. • DCP – Device Control. This is a very simplistic daemon. It has 2 functions, ejection of tapes from the tape drive and execution of NetWorker CLI when requested by the Server. • Rotation Policy: This is the Policy(s) that control the movement of tapes from onsite to offsite storage and back.

38. Multiple OS Platforms Supported AlphaStor Server runs on AlphaStor Server AlphaStor LCP/DCP Sun Sun IBM HP True64

39. History of AlphaStor • Developed by company called SCH Technologies • Private company owned by investor group • Ran by Ed Bauer • Original name was Software Clearing House • Acquired by Legato in 2001 • Came from a need in the market place for a heterogeneous Mainframe class tape management system. • Only product that had that ability was REELLibararian, which was EOL’d. Owned by STK who decided get out of the Backup/Recovery Software market. • Originally developed to be able to do tape management for a multitude of “data movers”. NetWorker, Veritas, TSM, etc. • NetWorker was “first” datamover selected due to ease of interface protocol.

40. Installation • AlphaStor Server • Install Shield for Windows; pkgadd for Solaris • Can install in any available disk • Default: Windows – C:/AS; Unix - /AS • Not recommended to install on same server as the NetWorker Server • LCP • Windows: Install shield; Solaris – pkgadd; Other: install script • Requires control path to the Library • Can be any server in the network. • DCP • Windows: Install shield; Solaris – pkgadd; Other: install script • Install on all servers that are NetWorker Servers and Storage nodes with tape drive access

41. AlphaStor allows for multiple NetWorker Datazones to utilize the use of the Tape libraries and drives. AlphaStor Device Management Datazone 1 Datazone 2 AlphaStor Server AlphaStor Server

42. AlphaStor Libraries • Works with most of the same libraries that NetWorker works with. • IBM, StorageTek, HP, ATL, Qualstar, ADIC, etc. • Works with IP controlled libraries (IBM 3494), and ACSLS controlled libraries • Supports most of the tape devices that NetWorker will support. • LTO • DLT • AIT • 8mm • 3592
