EADR for Cell Server - DP 8.1X on Windows 2012 R2

With Data Protector 8.XX the process to create disaster recovery images has been changed. Since the new version, the backup of the internal database is separated from the filesystem backup of the cell server. Hence, the “makeiso.cmd” (see https://www.data-protector.org/wordpress/2011/03/recover-cell-server-with-enhanced-automated-disaster-recovery/) is no longer working. With the separation it is necessary to provide 2 session id’s for the command omniiso; a session id from the filesystem backup and a session id from the IDB backup. As a preparation for a disaster and to automate the creation of the recovery image new batch files were created. Please see the guide below and how to implement the new scripts. The guide is valid for Data Protector version 8.10 and 8.11 only and was tested with Windows 2012 R2. For Data Protector version 8.0X the scripts will not work, as the option -anyobj is not available for the omniiso command. However, with some modifications it will be possible to run the scripts as scheduled task.

[wpdm_file id=23]

Requirements and implementation:

On cell server the correct version of the WAIK/ADK is installed. When Windows 2012 R2 is used, the version “ADK for Windows 8.1” is required.
The batch files (see download link) are copied into the Data Protector “bin” Folder (i.e: D:\Program Files\Omniback\bin).
The backup of the filesystems for the cell server is done using the Options “Copy Recovery Set to disk” (Filesystem Options – Advanced – Tab Other) and “Detect NTFS hardlinks”, “Backup share Information for directories” and “Use Shadow Copy” (Filesystem Options – Advanced – Tab WinFS Options).
The backup of the filesystems for the cell server is done using a separate backup specification (no other client) and as Post-exec script the batch file EADR_CS_FSBackup_Post.cmd (to be executed on cell server) will be inserted (Backup Specification Options – General – Post-exec).
The backup of the internal database from the cell server is created with no schedule (will be started by the filesystem backup) and as Post-exec script the batch file EADR_CS_IDBBackup_Post.cmd (to be executed on cell server) will be inserted (Backup Specification Options – General – Post-exec).
In file “EADR_CS_FSBackup_Post.cmd” the following changes must be made: variables OMNIHOME, OMNIDATA and IDBBACKUP (name of the IDB backup specification) must be modified, depending on existing environment.
In file “EADR_CS_IDBBackup_Post.cmd” at least the following changes must be made: variables OMNIHOME, OMNIDATA, CELLSERVER, WAIKPATH and NETWORKSHARE must be modified, depending on existing environment.
The batch files are already prepared with variables, so see the values as example.

Hallo Daniel
Muss das Tape immer noch mit 64K blöcken beschrieben werden oder geht es nun auch mit 256K?
Geht das auch mit DP9 und WS08R2?

Danke

  Hi Rene,
  
  ja… Das ist ja eine Limitierung vom Betriebssystem, da im PE Mode die Treiber für Tape und Changer nicht vorhanden/geladen sind. Ich habe zwar mal einen Trick gesehen wie man die SCSI Adressen vor dem Discovery Prozess “umbiegen” kann, das ist aber alles aufwendiger und erfordert Reboots während des EADR Prozesses, so dass ich das nicht empfehlen kann. Ich würde daher für die Sicherung des Cell Servers weiterhin mit den 64K Laufwerken arbeiten.
  
  Grüße
  Daniel

Hallo Daniel
Habe diese konfiguration genommen, habe aber DP9 & Windows 2008 R2
Das Backup läuft ohne Fehler durch.
Beim Restore kommt er soweit das er das abgespekte Fenster von DP aufmacht und gleich Failed anzeigt.
Was mir noch aufgefallen ist, beim Network hat er ein rotes X also kein Netz verfügbar. da es aber der Cell-Manager selbst ist, denke ich nicht das es an dem liegt. Bin mir aber nicht sicher.
Im Debug log sagt er, das es keine Systempartition hat. nur das hat er und wird ja auch gebackupt.
Leider stehe ich hier an. Bin mir auch nicht ganz sicher ob es mit meinen Versionen und den hier angegebenen Versionen funktionirt. Bin für jeden Tipp dankbar.

  Hi Rene,
  
  seems the Media Agent used for the backup was not on the cell server.
  Can you share more information, session logs, etc.?
  
  Best regards

    Hallo Daniel,
    mit DP 9.0x funktioniert das skript nicht und das Restore bricht gleich ab, sobald es anfängt.
    Das Problem ist, dass Objekte für System Partitionen nicht in recovery.srd in der ISO mittels des Befehls inkludiert sind.
    Lösung:
    1. omnisrdupdate in post skript IDB um recovery.srd zu erstellen.
    2. omniiso Befehl die erstellte Datei anschließend benutzen, anstatt was in dr\srd zu benutzen

Thank you so much for the scripts and excellent documentation. I have DP 9.01 installed on Windows 2008R2 Server. After following you instruction I have successfully created a EADR of my Cell server.

Pointing to the correct WAIKPATH for Windows 2008R2 was all that was need. C:\\Program Files\\Windows AIK

Hallo Daniel,
ich teste gerade das EADR des Cellserver unter DP9.1 und Server 2008 R2.
Soweit läuft der Backup gut durch lediglich beim erstellen des ISO-Image bekomme ich folgende Fehlermeldung.

Creating the ISO image …
[Major] From: omniiso@cellserver.com \”omniiso\” Time: 14.01.2015 16:24:59
Cannot read from SRD file C:\\Programdata\\Omniback\\Config\\Server\\dr\\srd\\cellserver. Aborting.

Hast du eine Idee warum er nicht auf die Datei zugreifen kann.

Danke und Gruß
Richard

  Hi Richard,
  
  kannst Du mal bitte an das Kommando “-debug 1-200 isodbg.txt” anhängen und mir es dann per Mail senden?
  Möglicherweise muss ich das Skript für DP 9 anpassen und testen.
  
  Grüße
  Daniel
