Title: Archiwizacja danych - przyklady


1
Archiwizacja danych - przyklady
  • Hierarchical Storage Management
  • Hierarchiczne zarzadzanie zasobami

2
Ograniczenia Backupu
  • Backup nie zabezpiecza ciaglosci bezpieczenstwa
    danych
  • Najszybciej zuzywajace sie nosniki
  • Tasmy nie sa interaktywnym nosnikiem
  • Informacja rozlozona jest na wielu nosnikach
    (dlugi dostep)

3
Co to jest HSM?
  • Hierarchical Storage ManagementSystem
    przechowywania danych, który automatycznie
    migruje je pomiedzy drozszymi i tanszymi mediami.
    Koszt jednostkowy szybkich urzadzen pamieci
    masowej, jak np. dysków twardych jest duzo
    wiekszy od wolniejszych jak napedy MO lub napedy
    tasmowe. Rozwiazanie azeby wszystkie dane
    znajdowaly sie na szybkich i drogich urzadzeniach
    nie jest do zaakceptowania przez wiele firm. HSM
    przechowuje dane na wolnych urzadzeniach i
    stamtad kopiuje je do szybkiej pamieci dyskowej,
    które pracuje jako cache.

    storage to secondary storage without recalling
    data to primary storage
  • Data is backed up directly to backup media
  • Provides complete backup of your entire system
    for disaster recovery purposes

46
Disk Quota
  • Disk Quota
  • Tracks and controls disk usage on a per user, per
    volume basis

Backup Server Management
  • Network Storage Executive

50
NSE 8.0 Key Features
  • Data-centric orientation (not backup server
    centric)
  • Centralized administration of backup, restore and
    device operations
  • An intuitive user interface based on the
    Microsoft Management Console (MMC)
  • Policy-based management offers a more scalable
    way to manage and automate backup
  • Backup server pooling permits load balancing
    across Backup Exec servers with greater fault
    tolerance
  • Microsoft SQL Server 7.0 database integration
    provides a central database that stores all job,
    device, media and configuration information
  • SSO and GDM integration

51
Policy-based Job Management
  • Backup policies define how when data will be
    backed up
  • Task list identifies the different types of jobs
    within a policy
  • Each task defines the details of a specific job
  • Backup method
  • Device media
  • Schedule
  • Advanced settings

52
Backup Server Pooling
  • Group backup servers using drive pools
  • Target policies and jobs to drive pools
  • Load balancing
  • Jobs dispatch to first available backup server
  • Simplifies capacity planning
  • Fault tolerance
  • Offline backup server will not prevent job
    execution

53
Centralized History Logging
  • Results from all jobs are rolled up to the Master
    database
  • Job history details are available for viewing or
    reporting
  • Problem files (skipped or in use) are also stored
    in the database
  • History pruning controls depth of history and
    size of the database

54
Alerting Notification
  • Flexible variety of notification methods
  • Email
  • Exchange
  • Lotus Notes
  • SMTP
  • SNMP
  • Alpha-numeric pager
  • Event Log
  • Circuit Breaker stops alert overload

55
Consolidated Reporting
  • Over 20 new reports using Crystal Reports 7.0
  • All data stored in an ODBC-compliant database
  • Create custom reports if desired
  • Automate operations based on database states
  • Spot trends
  • Predict growth
  • Optimize performance
  • Manage media pools
  • Track service levels

56
Offsite Media Tracking
  • Track media location onsite and offsite
  • Reports direct operators to move proper media
  • Media discovered online will be moved
    automatically
  • Restore jobs will inform the user where the media
    is currently located
  • Create multiple offsite vaults to store media

57
Centralized Restore
  • Centralized catalog repository enables fast
    restore from any backup server
  • Not necessary to restore data using the original
    backup server
  • Dedicate restore tasks to a specific machine
  • This capability is impossible without a
    centralized catalog repository
  • Catalog partializing and pruning control catalog
    growth

58
NSE Benefits

    the administration of backup restore tasks
  • Easily scales with you as your network grows
  • Pool storage resources for more efficient
    resource utilization greater fault tolerance
  • Manage by exception with NSEs rich variety of
    reporting and alerting capabilities
  • Integrate with other Windows management tools by
    taking advantage of NSEs Microsoft
    component-based design (MMC SQL)
  • Trust the leaders in NT storage management for
    the highest level of NT compatibility

Storage area networkingSAN

Issues
  • Backups impact business productivity
  • Backups take too long
  • LAN bandwidth insufficient
  • Data grows exponentially (50-100 per year)
  • Certain applications have little or no backup
    window and require greater availability
  • Widely dispersed backup systems are too costly
    for IT to maintain and manage effectively
  • Each backup system requires care feeding
  • Difficult to automate

61
Traditional Approaches to Backup
  • Backup to locally attached tape devices
  • High performance
  • Does not require network bandwidth
  • Backup over the network
  • Consolidated device hardware
  • Centralized device and media management

62
Backup to Locally Attached Devices
Each Server has its own backup device
LAN
Server
Tape Device
63
Problems with this Approach
  • Hardware and media required for every server on
    the network
  • Cost of a library on every server is prohibitive
  • Considerable manual effort required to maintain
    many individual systems

64
Backup Over Network
Data Flow
Tape Library
65
Problems with this Approach
  • Significant network bandwidth is required
  • Network performance is seriously degraded
  • Network users are severely affected
  • Does not meet the needs of 7 x 24 operations
  • Modern tape drive performance far exceeds network
    performance
  • The network becomes the bottleneck

66
The Ultimate Solution
  • Achieve speeds of local backup
  • Dont utilize network bandwidth
  • Consolidate device hardware
  • Centralize device and media management

67
The Storage Area Network (SAN)
  • Replaces the conventional SCSI bus
  • Connects storage devices to a separate network on
    the back end of the server
  • Storage devices may be simultaneously connected
    to many servers at once
  • Usually implemented using Fibre Channel
    technology
  • Current SAN topologies use a Fibre
    Channel-Arbitrated Loop (FC-AL)

68
Shared Storage Option Architecture
Data Flow
Storage devices
Tape Libraries
69
Backup Exec Shared Storage Option
  • Allows multiple Backup Exec servers to share
    backup devices directly attached across a
    storage area network or SAN
  • Consolidates storage to fewer centralized tape
    devices with greater capacity backup
  • Performance comparable to local speeds
  • Backup traffic removed from the main network
  • Support for Windows NT and Novell NetWare
  • Currently NT NetWare servers must reside on
    separate loops

70
Disaster Recovery
71
What Happens IF .......
72
The Recovery Problem
  • Without automated solution one has to
  • Collect and install system configuration files
  • Manually re-partition and format H/D
  • Manually re-install profiles and drivers
  • Manually re-install Backup program
  • Identify last Backup Tape
  • Re-catalog the backup tape
  • The above is all prone to Human Error

73
How IDR works ?
  • Three Phases of Implementation
  • Initial preparation of Disaster Disks
  • On Installation of IDR creates four disks
  • Three are modified Windows NT setup disks
  • The fourth is the IDR disk that contains
  • Restore Engine for Backup Exec
  • And server specific configuration Information
  • Automatic update of IDR information via regular
    backup
  • IDR is integrated into Backup Exec all
    information about full / Incremental backup is
    stored and any new server configuration changes
    is recorded.
  • This ensures that current information will be
    available on a Recovery
  • Recover after a Disaster

74
Recovery phase
  • First replace faulty HD or Server
  • Boot with IDR disks and NT CD
  • Disk partition sizing configuration and profile
    information is all restored with IDR
  • All applications and data is restored
    automatically off the most current backup tape
  • Can restore remote servers
