EVault Real Time Protection
EVault Real Time Protection used continuous data protection (CDP) technology to create recovery points
at near-constant intervals. Also called "continuous backup" or "real-time backup," CDP provides superior
data protection for your mission-critical business systems.

After it is set up, CDP automatically creates full backups (baselines) and intermediate recovery points
(incremental backups) at the intervals you specify. Data can be restored from any recovery point, in entire
volumes, one file at a time, or in any increment necessary.

This CDP solution provides the following capabilities:

       Provides a recovery point objective (RPO) in the sub 5-minute timeframe

       Works as a complete stand-alone solution, which can be easily deployed into your existing
        infrastructure

       Creates backups as images

       Integrates tightly with Bare Metal Recovery (BMR)

       Maintains backups for up to two weeks

       Provides a recovery time objective (RTO) of 1 GB per minute

       Allows for full data volume or single-file restoration

       Includes multiple deployment options

       Works in the background, allowing you to focus on other system tasks knowing your data will be
        available for restore if necessary

The following are some sample scenarios in which CDP can help:

       Disk Failure: A server responsible for storing sales contracts experiences complete disk failure at
        12 pm on the last day of the quarter. The failure is discovered almost immediately. The drive is
        replaced and the data volume restored to 11:55 am.

       Virus Infection: The system volume of the server responsible for storing sales contracts gets
        infected by a virus during the last week of the quarter. This infection is discovered at mid-day on
        Wednesday. The server administrator restores the data volume back to 8 am on Monday.

       Exchange Server Failure: A broker/dealer hosts its MS Exchange server on a Windows machine.
        A server begins to fail at 1 am. The problem is not isolated until 8 am PT, hours after the East
        Coast office begins its day. Every minute the server is down, customer orders cannot be received
        or confirmed via email. The office is forced to receive all orders through the call center, and many
        are not received at all. The server administrator uses BMR to configure a backup machine to act
        as the Exchange server, seeds it with the system volume as of 12:30 am and the data volume as
        of 7:55 am.

       SQL Server Rollback: A company begins their open enrollment period on November 15th. Days
        into the enrollment, the HR administrator learns that the wrong health plan options were posted
        on the enrollment site; all enrollment transactions need to be rolled back. The server
        administrator replaces the SQL Server instance with the clean database that existed at midnight
        on November 15th.




                                                                                                              1
CDP is not a replacement for traditional backup solutions. You will continue to use your existing backup
systems to handle the following tasks:

       Long-term backup

       Archiving

       Compliance

This CDP solution has two components:

       The agent works in the background to create recovery points.

       The desktop application is used to configure the agent, monitor its activity, and perform
        restoration. The desktop application can be closed while the agent is still working to protect your
        system.


Setting up CDP
Hardware requirements
CDP is a high-performance data protection solution. It leverages random access capabilities of hard disk
drives to reconstruct images of protected volumes as they existed at various points in time in the past.
Powerful new capability is made possible due to the shrinking costs of disk storage capacity. As of this
writing, the cost of the disk storage needed to protect 150GB of allocated data storage space is only
about $119.

CDP can use the following resources to store recovery points:

       Internal hard drive

       External USB or firewire drive

       SAN

Note: CDP does not currently support using NAS for storage of recovery points.

Storage requirements:

       The recommended amount of space for data storage is about 2.5 times the size of the volume(s)
        to be protected.

       The recommendation of 2.5 times the volume size provides enough space for recovery point
        generation for approximately one week assuming typical system use. Unusually high activity in a
        system generates more data in each recovery point, which will then require more space.

       Be sure to allow for possible growth of the data when planning your system.




                                                                                                              2
Software requirements
This software requires the following to be installed on your system:

       .NET 3.0

       Visual C++ 2005 Runtime Library SP1

       MSI Installation Engine

Supported operating systems:

       Windows XP

       Windows Server 2003

       Windows Server 2008

Installing CDP
    1. Download and start the setup program.

    2. Review the license agreement and click Accept to continue.

    3. Select the folder where you want to install the software and click Next.

    4. Review the install configuration and click OK to begin installation.

Configuring CDP
Configuration is where you set up which drives will be protected and how often, and where the recovery
data will be stored.

When CDP first starts up, it creates a new baseline, which is a full backup of the protected volumes. Then
it creates recovery points at the intervals you specify. Recovery points are incremental backups that
contain only a record of the changed data.

    1. From the Options menu, select Configure CDP Agent.

    2. Click Next to continue to the next screen of the wizard.

    3. Click Next to continue.

    4. Select the volume(s) you wish to protect. Click Next to continue.

    5. Select the location where the backup data is to be stored. Click Next to continue.

    6. Enter the frequency, in minutes, at which you want CDP to create recovery points.




                                                                                                         3
    7. Select the day of the week and time of day when you want the new baseline to be created, then
        click Next to continue.

       Note: Because creating a baseline is a resource-intensive activity, it is recommended that you
       schedule this to occur during off-peak hours. If you are using Open File Manager software with
       your file-based backup solution, schedule your CDP baseline such that it does not overlap with
       your scheduled file-based backup window .

    8. Review the summary information then select when you would like the first baseline to be
        generated. Click Next to begin data protection.

Configuring email notification
The CDP software can be configured to generate email notifications.

To configure email notifications:

    1. From the Options menu, select View Settings.

    2. Select the Notification Options tab.

    3. Provide the email configuration information.

    4. Click Commit Changes.

Advanced settings
The CDP software provides advanced settings that you can use to fine-tune system performance and
user experience.

To edit or view the advanced settings:

    1. Click Settings on the Quick Tasks list.

    2. Select the Advanced tab.

    3. Select or change the options as needed.
       CDP Disk Access Priority: If you want to allow other processes to take priority over CDP
       recovery point generation, adjust this setting. Lowering CDP's priority will reduce the frequency of
       disk I/O when generating recovery points. Note that this can cause recovery points to take longer
       to complete
       Busy System Notification: This is the number of minutes that CDP will keep trying to create a
       recovery point before warning you that a recovery point could not be created. If your system is
       frequently busy you may allow the software more time to initialize by increasing the value of this
       setting. If it is critical that your system generate recovery points at regular intervals, you can
       decrease the value of this setting in order to be notified sooner when the recovery point generation
       is delayed. Note that this value does not change the number of times the software will retry to
       generate a recovery point, it only changes the number of retries that can occur before a notification
       is sent.
       Clear all “Don’t show again” flags: Some messages that the software displays include a
       checkbox labeled "Don't show this message again" for suppressing future display of those
       messages. To re-enable displaying of these messages, select this option.

    4. Click Commit Changes.



                                                                                                              4
Running CDP
Starting CDP
After configuring CDP, you may start protecting your data. When CDP starts, it creates a baseline and
then begins generating recovery points at the interval specified at configuration time.

On startup, you have the option to create the new baseline immediately, or to wait until the next regularly
scheduled baseline. Because creating a baseline consumes some system resources, you may want to
wait until an off-peak time to do this. Note that recovery points are not created until after the baseline has
been created.

To start CDP:

    1. From the Backup menu, select Start CDP Agent.

    2. Click OK to start CDP with the current configuration.

       Note: If the configuration has not been defined, you are prompted to create one.

Creating a recovery point
At any time during CDP operation you can manually create a recovery point. Creating a manual recovery
point is useful before performing such operations as installing patches to the operating system, or
installing software that has a risk of rendering the system unstable.

When you manually create a recovery point, the CDP timer resets so that the next recovery point is
created at the interval specified in configuration. For example, if the interval is 5 minutes, the next
recovery point is created 5 minutes after the manually generated recovery point.

To create a recovery point:

    1. From the Backup menu, select Create Recovery Point.

    2. Click OK to create a recovery point.

Creating a new baseline
A baseline is a full backup of the volumes that CDP is configured to protect. Upon startup CDP creates a
new baseline. However, a new baseline can be manually created when needed.

Because creating a baseline consumes some system resources, you may want to wait until a non-peak
time to do this. If you need to create a baseline during peak system use, adjust the CDP Disk Access
Priority to reduce the impact on system resources (see Advanced Settings for more information).

Note: CDP stores up to two baselines and the recovery points that go with them. Each time a baseline is
created, the oldest baseline and all recovery points based on that baseline are deleted. This is an
important consideration when creating baselines - be sure to schedule creation of baselines with this
behavior in mind.

To create a new baseline:

    1. From the Backup menu, select Generate Baseline.

    2. Click Yes to create a new baseline.




                                                                                                             5
Pausing vs. stopping
Stopping CDP halts all backup processing by the CDP software. Data changes are not tracked and
recovery points are not created. When CDP is restarted, it must create a new baseline so that it can begin
creating recovery points based on that baseline.

Pausing stops recovery points from automatically being created, but changes to the data are still tracked.
When CDP is resumed, recovery points can continue to be created. A new baseline is not needed after
CDP has been paused and resumed.

Pausing CDP
Pausing CDP can be useful when performing operations during which you wish to minimize the overhead
of generating recovery points.

To pause CDP:

    1. From the Backup menu, select Pause Recovery Point Generation.

    2. Click Yes to pause CDP.

Resuming CDP
If CDP operation is currently paused, you restart it using Resume. When operation is resumed, a recovery
point is created immediately if any were missed during suspended operation. If no recovery points were
missed, CDP stays on schedule, creating the next recovery point at its regularly scheduled time.

To resume CDP:

    1. From the Backup menu, select Resume Recovery Point Generation.

    2. Click Yes to resume CDP.

Stopping CDP
You may need to stop CDP to facilitate certain types of system troubleshooting. When CDP is stopped,
recovery points are not created and data changes are not tracked. This option should be used with
caution because it leaves your system's data unprotected. Whenever possible, it is preferable to pause
CDP instead of stopping it.

To stop CDP:

    1. From the Backup menu, select Stop CDP Agent.

    2. Click OK to stop CDP.




                                                                                                         6
Restoring your data
Mounting a recovery point
Using the Mount option, you can access data at any level: volume, folder, or file. When a recovery point is
mounted, Windows refers to the recovery point image by a letter, the same as drive partitions or volumes.
Therefore, you can access it like any other volume on your system.

If you want to recover specific files or folders, mount the recovery point and then select which data to
recover. The data is shown as a read-only volume. You can use any file browsing utility (such as
Windows Explorer) to copy files or folders to your working system.

Note: You can also use this option to copy an entire volume to another, smaller volume. Restore requires
that the new volume be the same size or larger, whereas Mount does not.

Mounting a recovery point does not interfere with other CDP operations such as generating new recovery
points or restoring full volumes - these operations can continue while a recovery point is mounted.

Only one recovery point can be mounted at a time. To mount a new recovery point, unmount the one that
is currently mounted.

To mount a recovery point:

    1. Add a new drive letter in Windows.

    2. From the Restore menu, select Mount Drive from Recovery Point.

    3. Click Next to continue to the next screen of the wizard.

    4. Select (click) the recovery point you want to mount. Click Next to continue.

    5. Select the volume to be recovered.

    6. Select the volume where you want to place the recovered data. This needs to be an unused drive
        letter. See Available volumes for more information. Click Next to continue.

    7. Verify that your selections are correct, and click Next to mount the volume.

    8. One the volume has been mounted you can:

        Leave the Open Mounted Drive checkbox selected and click Finish to view the files and folders
        in Windows Explorer.

        OR

        Deselect this checkbox, click Finish, and then use another file browsing utility to view and restore
        the data.




                                                                                                           7
Restoring a volume
CDP provides you the ability to restore an entire volume as it existed at the point in time when the
recovery point was created. A full volume restore is used when a hard drive fails and one or more
volumes on that drive are lost. The drive can be replaced by one or more new drives. Restore can also be
used to replicate a system or data volume image to another volume, or to roll back a data volume to a
previous image. The restore operation copies the entire volume, including the formatting, to the new
location.

You can restore to any location except the system volume. If you need to restore the system volume, you
can use BMR, a separate module that works with CDP.

If you need to restore specific data, such as a folder or file, you can mount a recovery point to access the
data directly. See Mounting a recovery point for more information.

Note: Recovery point generation is suspended during the restore and will automatically resume when the
restore is complete.

To prepare your system for the restore:

       Identify partitions or formatted volumes where each volume is to be restored. Note that the
        restore location must be at least as large as the volume to be restored.

       Use the Disk Management shortcut in the restore wizard if you need to make volume and partition
        changes in preparation for the restore process.

       If you wish to restore data for a volume that was only partially utilized and you prefer to use a
        smaller volume or partition, you can use Mount Volume and copy the contents of the Recovery
        Point volume to the desired destination.

To restore a volume:

    1. From the Restore menu, select Restore Drive from Recovery Point.

    2. Click Next to continue to the next screen of the wizard.

    3. Select the recovery point you want to restore from. Click Next to continue.

    4. Select the volume to be restored.

    5. Select a raw partition or formatted volume where you want to place the recovered data. See below
        for more information. Click Next to continue.

    6. Review the restore summary and click Next to begin restoring the data.




                                                                                                               8
Available volumes
When you are using the restore wizard, you can only restore to volumes that are available. A volume is
NOT available if it is:

        Currently being protected by CDP (stop CDP if you want to restore over a protected volume).

        A system volume.

        Labeled A or B (these drives are reserved).

        A read-only volume.

        Smaller than the volume that is being restored.

        Known issue: If a volume appears to be the same size as the volume being restored, but it
        doesn't appear on the list of available drives, it's possible that the Windows disk manager created
        the volume slightly smaller than the size shown. Create a new, slightly larger volume for the
        restore.

Bare Metal Recovery
If you want to accomplish a bare metal restore you will need to use the BMR plug-in, purchased
separately.

Following are some scenarios in which BMR would be required:

        Hardware failure.

        A virus which renders the system unbootable.

        The system is destroyed but the backed up data is intact. The data can be restored onto a new
         hardware configuration.

From within BMR, you can restore data from a CDP recovery point.

Notes:

        While the system drive is being restored, CDP cannot create recovery points. When the restore is
         complete, CDP will need to create a new baseline to ensure the integrity of future data
         restoration.

        If the system drive is restored to a time before CDP was configured, CDP will need to be
         configured again before it can create new baselines and recovery points.




                                                                                                              9

              Stop CDP Agent            When the CDP Agent is running, choose this option to stop it.
                                        Note that recovery points will not be created while the CDP
                                        Agent is stopped, and a new baseline will need to be created
                                        when the CDP Agent is restarted.

              Pause Recovery Point      Choose this option to temporarily stop generating recovery
              Generation                points. The CDP Agent will continue to track disk writes so that
                                        when CDP is resumed, it can immediately start creating new
                                        recovery points without the need for a new baseline.

              Resume Recovery           When recovery point generation is paused, choose this option to

Quick tasks
The Quick Tasks list, located on the left side of the CDP window, provides shortcuts to commonly used
views and tasks.

The options are as follows:

Option                    Action

View Backup Status        Shows the current CDP status.

Recover                   Shows the Recovery Center, with information and links for restoring data.

Pause                     When CDP is running, choose this option to stop generating recovery points,
                          but continue tracking disk writes. This enables CDP to start generating
                          recovery points on resume, without doing a new baseline.

Stop                      When CDP is running, choose this option to stop it. Note that recovery points
                          will not be created while CDP is stopped, and a new baseline will need to be
                          created when CDP is restarted.

Glossary
Baseline:                  A full copy of a set of volumes backed up at a single point in time.

BMR:                       Bare metal recovery. This type of recovery is required for a system volume.

CDP:                       Continuous Data Protection - The goal of continuously backing up data. CDP
                           achieves near-CDP by supporting an RPO within minutes.

CDP Agent:                 The CDP Agent works in the background to create recovery points.

CDP configuration:         A configuration in CDP includes a set of drives to protect, a location for
                           backing up the drives, and an interval at which to create recovery points.

CDP desktop application: The desktop application is used to configure the CDP Agent, monitor its
                         activity, and perform restoration. The desktop application can be closed while
                         the Agent is still working to protect your system.

Mount:                     To make a recovery point available to the system so that data can be
                           recovered from that recovery point.

Rebaseline:                A new full copy (baseline) of a set of volumes. Note: CDP does not create
                           recovery points during rebaselining.

Recovery point:            A point in time when an image is backed up. CDP allows you to restore data
                           from a specific recovery point.

RPO:                       Recovery Point Objective - The interval at which recovery points are created.

RTO:                       Recovery Time Objective - The desired rate at which data will be restored
                           after a failure.

Unmount:                   When a recovery point is available to the system, unmounting makes it
                           unavailable. This enables another recovery point to be mounted.
