    Disaster Recovery Readiness

    Why Backup

    Computer failures due to various reasons can lead to
     loss of data and time –

      •   Loss of data due to database corruption
      •   Loss of data due to Virus infection
      •   Loss of data due to Hardware Failure
      •   Crash of machine due to failed application installation.
      •   Increased down time to bring back the computer after failure
          by installing operating system and all the applications again.

    Without a backup this loss of data and time would be
     permanent and irrecoverable.

    Backup – for Disaster Recovery Readiness

    Backup helps to –

      • Rapid recovery of data
      • Recover operating system along with applications and
      • Recover to different and dissimilar computer.
        Selectively         in
      • S l ti l recover i case of Vi        infection.
                                     f Virus i f ti
      • Recover to the correct state and become operational
        immediately after recovery

                               j                      p y               y
           You DO NOT need a major disaster to need rapid system recovery.
                  Everyday occurrences can bring a system down.

    Disaster Recovery Readiness

    Disaster recovery readiness can be achieved by –

      • Having a proper backup plan in place
      • Having backups stored at a quickly and easily accessible yet a
        safe location.
      • Having a proper recovery procedure in place.

    Key Concepts

      Types of Backups
    .Types   of Backup
    File Based Backup
      • Files are backed up by copying them to a folder or CD/DVD.
      • Not characterized as Rapid disaster recovery.
      • Prerequisite : Operating system and application must be installed.

    Disk Based images
      • Entire Disk is backed up to create a single backup image file.
      • Sector level Point-in-time snapshot of disk at the time backup was started.
      • Qualifies for rapid restores
      • Restores OS, all apps, all service packs, all configuration with minimal

      Types of Disk Based backups
    .Disk   Based backups are further classified as

    Full Backup
      • A full backup stores all data selected for backup
      • A full backup forms the base for incremental and differential backups
      • A full backup is self-sufficient – previous backups not required.

    Incremental Backup
      • An incremental backup is backup of changes done only from last backup.
      • For complete restore all incremental and latest full backup are needed .
      • Useful for rolling back any one of multiple saved states

     Experion Backup & Restore Overview

       Experion Backup & Restore(EBR) - Overview
     Honeywell Offers EBR as a complete backup & restore
     solution for Experion/TPS nodes

         operations without any impact
       • Allows user to adjust the performance setting to minimize impact of local
         and network resources
       • Allows user to restore to same node or similar node or dissimilar node
       • Allows user to restore files and directories.

        Experion Backup & Restore – Features
     EBR Features –
     Disk, Volume, Folder & File level backups
     Can create both file based or disk based backup

     Online Backup

     Centralized administration
     Creating and monitoring backup tasks for multiple stations and servers from a
     single management console.

     Flexible Performance
     Fl ibl P f
     Can throttle backup priority, write speed and network speed.

        Experion Backup & Restore – Features
     EBR Features –
     Flexible backup image location options
     Backs up drive image to Local Disks, Network, CD/DVD, SAN, Tape

     Bootable Recovery CD
     Offers a bootable recovery CD for bare metal restoring
     Allows creating a customized bootable recovery CD by adding drivers.

     Restore from Network drive storage or from images on CD
     Connect and recover the backups stored on network location or DVD or USB
     hard drive or Tape Drive.

     Mount Images
     Mounts backups as local drives for auditing backups or restoring individual files.

        Advanced Options
     • Hourly, Daily, Weekly, Monthly and Event driven schedules are
     • Honeywell recommends time based backup schedules.
     • Typical  Daily one incremental backup
        yp            y                      p
                  Weekly one full backup
                  Monthly a full backup.
     Backup image can be compressed to different compression levels
     • Standard –50% Compression
     • Medium - 40% Compression
     • High     - 40% Compression, reduces recovery time but loads CPU.
     • None     - Takes longest time to recover, does not load CPU.
      Selecting best suitable compression level is trade off between resource utilization and recovery
     Advanced Options
     Retention limits
     • Retention rules are for deleting the unwanted older backups
     • Typical  Delete daily backups older than 7 days,
        –         Delete weekly backups older than 2 weeks
        –                                             months.
                  Delete monthly backups older than 1 months

     Pre and Post capture commands
     For Non VSS aware databases
        – Pre-data capture command suspends the database and flush all caches
          before snapshot.
                       p                                  p
        – Post-data capture command resumes the database operations after the
          snapshot is created.
     Honeywell customizes it for Experion
        – Pre capture command for creating Experion checkpoints to ensure that
          backup has latest checkpoints.

     Backup planning & Best Practices

     Backup Plan
     For a good backup plan

     • Identify nodes need to be backed up
     • Identify drives need to be backed up
     • Identify backup image archive location
     • Identify offsite storage which is safe and easily accessible.
     • Decide Scheduling frequency Based on
        – Rate of change of data
        – Database availability
          Value f data
        – V l of d t

     Backup Plan
     For a good backup plan

     • Identify backup type needs such as
        – Full
        – Full + Incremental
        – Full + Incremental + Full

     • Identify need of disk space for storage of backup images based
        – number of systems
        – rate of change
        – images to be retained

      Backup Best Practices
                      p       p                            p
       • Plan to checkpoint Experion databases before backup

       • Run HM backup using TPN backup & Restore tool before backing
         GUS / APP.

       • Stagger start times

       • Use offsite storage at least once a week.

       • Perform a full backup every time after disk defragmentation is done

       • Avoid backup through router - may impact performance.
         Use backup storage location within a cluster.

       • Periodically make sure disk is fully functional and does not contain
         bad sectors or file system errors.

       Backup Best Practices
        • Store backup of system drive on local node

     Don’ts (while backup is being created)
        • Perform Server synchronization

        • Perform rebuilding or restoring databases.

        • Run disk defragmentation

        • Run applications such as scandisk

        • Do check-pointing

        • Run routine maintenance tasks such as policies or service pack or
          security updates from domain controller

     Avoid the time duration of routine maintenance activities for backup
     Recovery planning & Tips

     Recovery Plan

     Being prepared
     • Identify the possible disaster scenario
     • Identify possible recovery procedure for each disaster scenario
       and choose one.
     • Identify recovery task performer
     • Identify need for recovery schedule
     • Identify hierarchy or priorities of operating areas to be recovered
       and list them on order
     • Identify & list order in which system in a area are to be recovered

                   The best Plan is always being ready and prepared.   Prepared

      Recovery Tips
     • All the data on the target disk will be replaced, be watchful for non-
       backed-up data.

     • Periodically make sure disk is fully functional and does not contain
       bad sectors or file system errors.

     • The target drive need not be of same size as the old drive
       Target drive >= Used disk space old drive

     • Ensure that driver for NIC card, motherboard, hard disk controllers are
       readily available.

     • Make sure to backup OS and boot loader and recovered then together
       if OS and loaders are on different volumes.
