Windows Automated System Recovery (ASR) with IBM Tivoli Storage Manager Overview

Windows Automated System Recovery (ASR) with IBM
Tivoli Storage Manager Overview
2
What is ASR?

• Feature of Windows XP and Windows 2003 that
  provides a bare metal restore framework for
  backup vendors to exploit
• TSM interfaces with ASR to provide a method to
  recover from a catastrophic system or hardware
  failure. It should be used only after all other
  repair options have been exhausted.
• The Goal of an ASR restore is to recover the boot
  system drives plus system state, not
  application and user data

3
What software do I need?

• Recovering a Windows XP SP1 system requires a
  Windows XP SP1 integrated (slipstream)
  installation CD.
• The TSM client installation package used on the
  TSMCLI CD you create for ASR recovery must be at
  the same or higher level than the level of client
  used to create the backups for the system being
  recovered.
• ASR requires a TSM v5.2.0 or newer client.
• Additionally ASR for Windows 2003 requires a
  v5.2.0 or newer TSM server.

4
What are the hardware restrictions of ASR?

• Target system must be identical to that of the
  original system, with the exceptions of the hard
  disks, video cards, and network interface cards.
• Target system must have the same number of disks
  as the original system.
• The size of each disk on the target system must
  be greater than or equal to the size of the
  corresponding disk on the original system.
• All disks must have 512 byte sectors.
• All disks (and only such disks) that are
  available to ASR on which to perform a recovery
  must be accessible.
• The ASR files must be accessible from a local
  floppy drive.
• The floppy and CD-ROM drives cannot be external
  PC-card drives.
• The original system must be an x86 or an Itanium
  machine.
• All basic volumes in the original system must be
  simple. Non-simple volumes are not supported. If
  a volume is mirrored, it must be a dynamic
  volume, not a basic volume

5
Preparing for ASR overview

• Materials required for ASR
• Bootable operating system CD-ROM
• User-created TSM client installation CD-ROM
• TSM-created ASR recovery diskette
• Incremental backup of system and boot drives
• Backup of system state
• Optional Local TSM backupsets containing
• System and boot drives
• System state
• Note For successful backup and recovery of user
  profiles on Windows 2003 you must use the
  procedure described in DCF 1176642 TSM backup
  and restore of NTUSER.DAT in a Windows 2003
  environment.
• TSM node password for machine being recovered

6
Preparing for ASR backup ASR files

• Select Backup from the main GUI screen
• Select Automated System Recovery entry in the
  tree and press backup
• Command line
• DSMC BACKUP ASR

7
Preparing for ASR create diskette

• Select Create ASR Diskette from Utilities menu
• Insert diskette into specified drive and press
  finish
• Command line
• LABEL A TSMASR
• DSMC RESTORE ASR A\

8
Preparing for ASR verification

• Make sure you backup ASR files before trying to
  create diskette
• Can use VIRTUALNODENAME to create a diskette for
  another machine (provided the ASR files have
  previously been backed up)
• Must BACKUP ASR prior to performing system boot
  drive incremental used for ASR recovery.
• Insure NLDLL.ASR and SMSS.ASR backed up
• QUERY BACKUP C\WINDOWS\REPAIR\.ASR

9
Including 2003 User Profiles in the ASR Process
10
Preparing for ASR 2003

• Edit the file TSMASR.CMD on the floppy disk
  created in the prior step. Place the two commands
  NTBACKUP and PAUSE following the dsmc restore
  systemservices line similar to the following
  example
• NETWORK
• dsmc restore \\TSMWIN2K3\C\ C\ -subdiryes
  -preservepathcomplete -replaceall
  -tapepromptno -nodenameNTBACKUP
  -optfiletsmasr.opt
• dsmc restore systemstate -asrmodeyes
  -nodenameNTBACKUP -computernameTSMWIN2K3
  -optfiletsmasr.opt
• dsmc restore systemservices -asrmodeyes
  -nodenameNTBACKUP -computernameTSMWIN2K3
  -optfiletsmasr.opt
• NTBACKUP
• PAUSE

11
Preparing for ASR - 2003

• Remove Passwordaccess generate from the
  tsmasr.opt file on the floppy if it exists
• Use Ntbackup.exe to backup the windows user
  profiles to local file storage. We will then use
  TSM to back up this file
• i. Create a script which lists all the instances
  of ntuser.dat and ntuserclass.dat into an
  ntbackup.exe
• ii. execute the script
• iii.Backup the ntbackup file created
• iv.Ensure the file was backed up
• DSMC Query Backup

12
End of 2003 User Profiles Additional Steps
13
Preparing for ASR back up system boot drives

• Perform complete incremental backup of system and
  boot drives
• System drive is partition containing ntldr and
  boot.ini
• Boot drive is partition containing Windows system
  directory
• Select drives from GUI backup screen and press
  backup
• Command line
• DSMC INCREMENTAL C

14
Preparing for ASR back up system state

• GUI
• Select entries from GUI backup screen and press
  backup
• Command line
• XP
• DSMC BACKUP SYSTEMOBJECT
• 2003
• DSMC BACKUP SYSTEMSTATE
• DSMC BACKUP SYSTEMSERVICES
• Verification
• XP
• DSMC QUERY BACKUP SYSTEMOBJECT
• 2003 (can use showmemberyes)
• DSMC QUERY SYSTEMSTATE

15
Preparing for ASR TSM CD-ROM

• User must create a TSM client installation CD
  using package-for-the-web (PTF) package
• Download the TSM client package from IBM FTP
  server
• Rename the package to TSMCLI.EXE. From a command
  prompt issue
• RENAME IPxxxxx.EXE TSMCLI.EXE
• Using the method described by your CD-ROM burning
  software, specify the volume label to be TSMCLI.

  application
• From the command window that says Press any key
  to continue Press a key to allow ASR to proceed
• The command file will exit, the machine will
  reboot. Remove the ASR diskette
• The OS will come up in a fully recovered state.

28
Recovering Windows 2003

• The operating system comes up in fully recovered
  state.
• Recovery of user data and applications can now be
  performed using traditional TSM restore
  facilities

29
Known Issues/ Restrictions

• If the Backup ASR command is not run prior to the
  full incremental, the ASR restore will fail.
• ASR can not be used to perform a restore on an
  authoritative primary domain in Windows 2003.
  This is a Microsoft Restriction- Article ID
  836421
• ASR is not always successful on a restore to a
  new drive of the same size. Please see DCF
  1193072
• Error "Setup was unable to format the drive"
  During Restore. See DCF 1193064 or Microsoft
  Article 817708

TSM Commands for ASR

• gtgt-BACKup ASR-----------------gtlt
• '- options-'
• Generates ASR files (asr.sif, asrpnp.sif,
  tsmasr.opt, tsmasr.cmd, waitforevent.exe) in the
  adsm.sys\ASR staging directory and backs them up
  to the ASR filespace on the server.
• gtgt-REStore ASR---destinationfilespec------------
  -----gtlt
• 
  '- options-'
• Restores ASR files to the specified location. By
  default files are restored to adsm.sys\ASR
  staging directory. An ASR recovery diskette is
  created by specifying the diskette drive as the
  restore location or by copying the files from the
  adsm.sys\ASR staging directory to a diskette.

31
TSM Options for ASR

• .-No--.
• gtgt-ASRMODE-------------------------------------
  ----gtlt
• '-Yes-'
• indicates that a restore is being performed in
  system ASR recovery mode. This option is used in
  the context of restore commands generated in the
  tsmasr.cmd file by the BACKUP ASR command only.
  It should not be used outside the context of ASR
  recovery mode.
• gtgt-COMPUTERNAME- -----ltcomputernamegt-----gtlt
• specifies the name of the computer for which
  system state recovery is being performed ASR
  mode. This option is used in the context of
  restore commands generated in the tsmasr.cmd file
  by the BACKUP ASR command only. It should not be
  used outside the context of ASR recovery mode.
