    Types of backup

    Full Backup:A Full backup is simply backing up all files on the system. Users may choose to update archive attributes if they plan on doing any of thefollowing 2 types of partial backups.

    Incremental Backup:An incremental backup is a backup that backs up only the files modified since the last backup. When running an incremental backup, userneed to update the archive attribute while backing up only modified files. Often the incremental backups are appended to the full backup sThe result is a tape with the changes that occurred daily. This type of backup is useful if the user wishes to have an audit trail of file usageactivity on their system and will enable them to restore a specific days work without restoring any changes made since that point in time. Tdo a full restore for 4 days after a full backup they must restore the full backup and all 4 data sets after it. Unlike the next type of backup.

    Differential Backup:A differential backup is a cumulative backup of changes made since the last full backup. It backs up modified files only but does not updatthe archive attribute. The list of files grows each day until the next full backup is performed clearing the archive attributes. This enables theuser to restore all files changed since the last full backup in one pass. These backups can be appended to the full as well, but they will hato keep in mind that each set can contain a different version of a file if that file changes daily. The data sets will always be at least as big athe previous differential (if no changes were made) and will continue to grow as files change. Once a files archive attribute is set it will bebacked up each day until after the full backup resets it's attribute bit.

    You can choose from three different backup methods. Most backup strategies use a combination of two or three of

    these methods.

    Backup Type Description Pros Cons

    full backup A complete set of all files youwish to back up. Think of this asyour 'reference set'. You onlyneed perform a full backupoccasionally.

    Provides a complete copy of allyour data; makes it easy tolocate files which needrestoring.

    Takes a long time and the mostspace on backup media;redundant backups created, asmost files remain static.

    incremental backup A backup of those files whichhave changed since the lastbackup of any type.

    Uses the lease time and space asonly those files changed sincethe last backup are copied; letsyou back up multiple versions ofthe same file.

    Makes the job of restoring filesfiddly, as you have to reinstallthe last full backup first, then asubsequent incremental backupin the correct order; also makeit hard to locate a particular fil

    in the backup set.

    differential backup A backup of those files whichhave changes since the last fullbackup. Should be performed atregular intervals.

    Takes up less time and spacethan a full backup; provides formore efficient restoration thanincremental backups.

    Redundant information stored,because each backup stores muof the same information plus thlatest information added orcreated since the last fullbackup. Subsequent differentiabackups take longer and longermore files are changed.

    Creating a Backup and Recovery Plan

    The backup and recovery plan establishes guidelines and procedures to prevent problems that might cause data loss or

    interruptions to your organizations operations, and to allow recovery as quickly as possible if such events do occur.

    Consider planning downtime or outages for the pilot in order to test rollback procedures, and, if applicable, disaster recovery an

    business continuity plans.

    Creating a Backup PlanThe importance of a backup plan cannot be overstated. When you begin rolling out Windows Server 2003 in the business

    environment, problems might arise that even the most thorough testing could not reveal. By making regular and reliable

    backups, you ensure that the team can restore the system to its original state if your pilot rollout process changes or fails.

    The backup plan should define procedures for:

  • 7/31/2019 Types of Backup

    2/11

    Backing up baseline configurations (the state of a computer before it is upgraded) so a computer can quickly be restored to its prior state.

    Backing up servers before they are upgraded.

    Backing up the most recent system and user data before you begin switching systems.

    Testing the restore process for each of the above processes using the backup files.

    In addition, the backup plan should identify who is responsible for performing backups, and should include the schedule for all

    periodic backups and periodic testing of backups, as well as instructions for labeling and storing all backup files.

    For more information about creating backup plans, see the Storage Technologies Collection of the Windows Server 2003

    Technical Reference (or see the Storage Technologies Collection on the Web at http://www.microsoft.com/reskit).

    Creating a Recovery PlanThe recovery plan describes the recovery and rollback process, which allows you to return your production system to whatever

    earlier state you require. Depending on the severity of a problem encountered in the pilot, you might need to return your

    production system to a baseline configuration or just roll it back to the state it was in at a particular point in time.

    Include the following elements in the recovery plan:

    A list of scenarios Analyze all of the systems involved in the rollout and identify the situations, or scenarios, under which

    problems are likely to occur. Determine which systems might be affected and the functional dependencies among them so you

    have a clear understanding of the larger impact that a single failure might have. Use these scenarios to create strategies that

    identify when and how to run backups and the types of recovery for which you need to plan.

    A definition of acceptable downtime Define how much downtime your organization can accommodate. If your organization

    cannot afford for systems to go down during normal business hours, you might plan to roll out the pilot, or parts of it, at night

    over a weekend. If systems must be operational at all times, you might plan to deploy servers and desktops on new computers

    and then quickly replace the old ones, instead of upgrading computers.

    A list of critical systems and processes In the event that a failure does occur, you need to know which systems are the

    most critical and must be brought back online first. If resources such as bandwidth are limited, you need to know which system

    have the highest priority and which should not take up network traffic. When evaluating how critical a system or process is,

    consider factors such as its effect on human health and safety, the legal liabil ity it exposes, the risk to corporate confidentiality,

    and the cost of replacement.

    A recovery strategy Your recovery strategy should define how you will recover data or systems in each of the scenarios you

    define in the recovery plan. This might include restoring data from backup tapes, switching over to redundant systems, rolling

    back to previous configurations, or other strategies. Include an additional procedure for recovering from severe data corruption

    your directory service if that becomes necessary. By having your recovery strategy in place, you can quickly restore your

    production environment to the required state so that work can continue with minimal interruption.

    A rollback strategy The rollback strategy defines how you plan to use backup and recovery procedures to return your pilot o

    production environment to the state it was in before changes were made. Specify the criteria that a problem should meet to

    warrant rolling the environment back to its previous state. For example, you might establish a system for classifying the severit

    of problems and describe which type of response is warranted by certain levels of severity. Also decide whether you need to ha

    different rollback strategies for different types of problems. For example, you might develop one procedure for backing out the

    entire pilot if the problem is pervasive and another procedure for backing out specific components if the problem is isolated.

    The roles and responsibilities for team members Make sure that every task in the plan is assigned to an appropriate team

    member, and that that person has the information needed to successfully perform required tasks. Consider including training in

    the plan.

    Have the backup and recovery plan reviewed by the project team and by those responsible for potentially affected systems. Aft

    the plan has been approved, test it to ensure that the processes you put in place work as expected.

    INSTALLING SOFTWARE

    How can I install Windows XP Pro on my computer?

    As a Microsoft Windows XP Professional support professional, one of your tasks may be to install the

    operating system.

    Step #1: Plan your installation

    When you run the Windows XP Professional Setup program, you must provide information about how to

    install and configure the operating system. Thorough planning can make your installation of Windows XP

    http://go.microsoft.com/fwlink/?linkid=4681http://go.microsoft.com/fwlink/?linkid=4681http://go.microsoft.com/fwlink/?linkid=4681

    Professional more efficient by helping you to avoid potential problems during installation. Anunderstanding of the configuration options will also help to ensure that you have properly configured your

    system.

    I won't go into that part right now but here are some of the most important things you should take into

    consideration when planning for your XP installation:

    Check System Requirements

    Check Hardware and Software Compatibility

    Determine Disk Partitioning Options

    Choose the Appropriate File System: FAT, FAT32, NTFS

    Decide on a Workgroup or Domain Installation

    Complete a Pre-Installation Checklist

    After you made sure you can go on, start the installation process.

    Step #2: Beginning the installation process

    You can install Windows XP in several methods - all are valid and good, it all depends upon your needs

    and your limitations.

    Manual installations usually come in 3 flavors:

    Boot from CD - No existing partition is required. Boot from the 6 Setup Boot Disks, then insert the CD - No existing partition is required (see the

    Create Setup Boot Disks for Windows XP page).

    Boot from an MS-DOS startup floppy, go to the command prompt, create a 4GB FAT32 partitionwith FDISK, reboot, format the C partition you've created, then go to the CD drive, go into the I386

    folder, and run the WINNT.EXE command.

    Run an already installed OS, such as Windows NT 4.0 Server. From within NT 4.0 go to the I386folder in the W2K installation CD and run the WINNT32.EXE command.

    If you want to upgrade a desktop OS such as Windows 98 into Windows 2000 Professional you can

    follow the same procedure as above (You cannot upgrade Windows 98 into W2K Server).

    There are other non-manual installation methods, such as using an unattended file along with a

    uniqueness database file, using Sysprep, using RIS or even running unattended installations from withinthe CD itself, but we won't go into that right now.

    It doesn't matter how you run the setup process, but the moment it runs - all setup methods look alike.

    Step #3: The text-based portion of the Setup program

    The setup process begins loading a blue-looking text screen (not GUI). In that phase you will be asked to

    accept the EULA and choose a partition on which to install XP, and if that partition is new, you'll be askedto format it by using either FAT, FAT32 or NTFS.

    1. Start the computer from the CD.

    2. You can press F6 if you need to install additional SCSI adapters or other mass-storage devices. Ifyou do you will be asked to supply a floppy disk with the drivers and you CANNOT browse it (or a CD for

    that matter). Make sure you have one handy.

    3. If you want, you can press F2 to run the ASR sequence. For that you need a good backup createdby the Windows XP backup program, and the ASR floppy disk. If you plan to install a new copy of XP -

    don't do anything.

    4. Setup will load all the needed files and drivers.

    5. Select To Setup Windows XP Professional Now. If you want, and if you have a previous installationof XP, you can try to fix it by pressing R. If not, just press ENTER.

    6. Read and accept the licensing agreement and press F8 if you accept it.

    7. Select or create the partition on which you will install Windows XP Professional. Depending upon

    your existing disk configuration choose one of the following:

    If the hard disk is unpartitioned, you can create and size the partition on which you will install

    Windows XP Professional.

    If the hard disk is already partitioned, but has enough unpartitioned disk space, you can create anadditional partition in the unpartitioned space.

    If the hard disk already has a partition that is large enough, you can install Windows XP

    Professional on that partition. If the partition has an existing operating system, you will overwrite thatoperating system if you accept the default installation path. However, files other than the operating

    system files, such as program files and data files, will not be overwritten.

    If the hard disk has an existing partition, you can delete it to create more unpartitioned space forthe new partition. Deleting an existing partition erases all data on that partition.

    If you select a new partition during Setup, create and size only the partition on which you will installWindows XP Professional. After installation, use Disk Management to partition the remaining space on the

    hard disk.

    8. Select a file system for the installation partition. After you create the partition on which you will

    install Windows XP Professional, you can use Setup to select the file system with which to format thepartition. Windows XP Professional supports the NTFS file system in addition to the file allocation table

    (FAT) and FAT32 file systems. Windows Server 2003, Windows XP Professional, Windows 2000, andWindows NT are the only Microsoft operating systems that you can use to gain access to data on a local

    hard disk that is formatted with NTFS. If you plan to gain access to files that are on a local Windows XPProfessional partition with the Microsoft Windows 95 or Windows 98 operating systems, you should

    format the partition with a FAT or FAT32 file system. We will use NTFS.

    9. Setup will then begin copying necessary files from the installation point (CD, local I386 or network

    share).10. Note: If you began the installation process from an MS-DOS floppy, make sure you have and run

    SMARTDRV from the floppy, otherwise the copying process will probably last more than an hour, perhapseven more. With SMARTDRV (or if setup was run by booting from CD) the copying will probably last a few

    minutes, no more than 5 max.

    11. The computer will restart in graphical mode, and the installation will continue.

    Step #4: The GUI-based portion of the Setup program

    The setup process reboots and loads a GUI mode phase.

    It will then begin to load device drivers based upon what it finds on your computer. You don't need to doanything at this stage.

    1. Click Customize to change regional settings, if necessary.

    Current System Locale - Affects how programs display dates, times, currency, and numbers.

    Choose the locale that matches your location, for example, French (Canada).

    Current Keyboard Layout - Accommodates the special characters and symbols used in differentlanguages. Your keyboard layout determines which characters appear when you press keys on the

    keyboard.

    If you don't need to make any changes just press Next.

    If you do need to make changes press Customize and add your System Locale etc.

    Note for Hebrew users: Unlike W2K, it is SAFE and it is OK for you to install Hebrew language supportat this phase.

    To install Hebrew support:

    After pressing Customize go to the Languages tab and select the "Install files for complex script andright-to-left languages".

    A warning message will appear. Press Ok.

    Warning: You must now press Apply!!!

    Setup will copy the necessary files from the installation point.

    You can now go to the Regional Options tab and select Israel in the Location drop-down list, and Hebrew

    in the Standards and Formats drop-down list. Click Ok.

    2. Type your name and organization.

    3. Type the product key.

    4. Type the computer name and a password for the local Administrator account. The localAdministrator account resides in the SAM of the computer, not in Active Directory. If you will be installing

    in a domain, you need either a pre-assigned computer name for which a domain account has been

    created, or the right to create a computer account within the domain.

    5. Select the date, time, and time zone settings.

    6. Setup will now install the networking components.

    After a few seconds you will receive the Networking Settings window. BTW, if you have a NIC that is notin the HCL (see the What's the HCL? page) and XP cannot detect it, or if you don't have a NIC at all,

    setup will skip this step and you will immediately go to the final phase of the setup process.

    Press Next to accept the Typical settings option if you have one of the following situations:

    You have a functional DHCP on your network.

    You have a computer running Internet Connection Sharing (ICS).

    You're in a workgroup environment and do not plan to have any other servers or Active Directory

    at all, and all other workgroup members are configured in the same manner.

    Otherwise select Custom Settings and press Next to customize your network settings.

    7. One thing you CAN do (you don't have to do it, it's your call - read more about it on the IncreaseInternet Connection Speed in Windows XP page) is to uninstall the Qos Packet Scheduler. Click it andpress the Uninstall button. If you want to keep it you can simply remove the mark from the QoS check-

    box. In anyway you can later install or uninstall it if you want.

    Keep the TCP/IP, Client for Microsoft Networks and the File and Print Sharing options selected.

    8. Highlight the TCP/IP selection and press Properties.

    In the General tab enter the required information. You must specify the IP address of the computer, andif you don't know what the Subnet Mask entry should be - you can simply place your mouse pointer over

    the empty area in the Subnet Mask box and click it. The OS will automatically select the value it thinks isgood for the IP address you provided.

    If you don't know what these values mean, or if you don't know what to write in them, press cancel and

    select the Typical Settings option. You can easily change these values later.

    9. In the Workgroup or Domain window enter the name of your workgroup or domain.

    A workgroup is a small group of computers on a network that enables users to work together and

    does not support centralized administration.

    A domain is a logical grouping of computers on a network that has a central security database forstoring security information. Centralized security and administration are important for computers in a

    domain because they enable an administrator to easily manage computers that are geographically distantfrom each other. A domain is administered as a unit with common rules and procedures. Each domain

    has a unique name, and each computer within a domain has a unique name.

    If you're a stand-alone computer, or if you don't know what to enter, or if you don't have the sufficient

    rights to join a domain - leave the default entry selected and press Next.

    If you want to join a domain (NT 4.0 domain of W2K/2003 Active Directory domain) enter the domain'sname in the "Yes, make this computer a member of the following domain" box.

    To successfully join a domain you need the following:

    The person performing the installation must have a user account in Active Directory. This account

    does not need to be the domain Administrator account.

    and

    The computer must have an existing computer account in the Active Directory database of the

    domain that the computer is joining, and the computer must be named exactly as its domain account is

    named.

    or

    The person performing the installation must have appropriate permission to create a domainaccount for the computer during installation.

    Also, you need to have connectivity to the domain's domain controllers (only to the PDC if on an NT 4.0

    domain) and a fully functional DNS server (only in AD domains). Read the Joining a Domain in Windows

    XP Pro and Requirements when Joining a Domain pages for more on this issue.

    Enter the Active Directory domain name (in the form of xxx.yyy, for example: DPETRI.NET) or the

    NetBIOS name of the NT 4.0 domain (in the form of xxx, for example: DPETRI). Press Next.

    Note: If you provide a wrong domain name or do not have the correct connectivity to the domain's DNS

    server you will get an error message.

    A username/password window will appear. Enter the name and password of the domain's administrator

    (or your own if you're the administrator on the target domain).

    Note: Providing a wrong username or password will cause this phase to fail.

    10. Next the setup process will finish copying files and configuring the setup. You do not need to do

    anything.

    11. After the copying and configuring phase is finished, if XP finds that you have a badly configuredscreen resolution it will advise you to change it and ask you if you see the new settings right.

    BTW, the minimum supported screen resolution in XP is 800X600.

    12. Setup finishes and boots Windows XP.

    13. A Welcome screen is the first thing you see. The computer checks your Internet connectivity(required for the mandatory Activation and voluntary Registration processes).

    You will be asked to register your copy of XP. You can decline if you want.

    14. XP will ask you for the default username that will log onto this computer. You can enter as manyas 5 users, but you can create more after the installation is finished.

    BTW, the Administrator is not shown as a valid logon option (read more about it on the Add the

    Administrator's Account to the Welcome Screen in XP Pro page).

    15. That's it! you're done!

    Now head towards the Customize a New XP Installation page.

    Before you begin any installation of Windows XP Professional you should: (where applicable)

    Make sure your hardware components meet at least the minimum system requirements

    Whenever practical, use the recommended minimum system requirements or exceed them

    Verify compatible hardware and software and obtain any required upgrade packs and new drivers before proceedingwith the installation; especially in an upgrade scenario

    Obtain any needed network information for your environment; DHCP or manually IP configuration, DNS and / or WINSinformation. Example, whether or not you're using IPX/SPX and need to install NWLink, etc.

    Back up any data on the current system before beginning an upgrade installation and verify that the back up is good

    Identify and plan for any advanced setup options you might require.
