VBus Use Case 1
Bare Metal Recovery
Servers need to be online and available 24x7 in todays global economy. In the case of a server disaster
causing downtime, it can be very costly to the company. The Server needs to be restored in the quickest
and most reliable way, and with the least amount of downtime.

Desired Solution
Restore the entire system as quickly as possible. Completely avoid reinstalling the operating system
which is too costly

How can VBus Help?
Using the VBus Recovery Environment, IT administrators can restore the entire system in minutes.
There is no need to create recovery media since VBus provides a bootable recovery CD. Using the
speed of the disk, the restore is much faster than restoring from tape. The server is restored to exactly the
way it was.

VBus Use Case 2
Live Server Backup
When taking server backups, IT administrators cannot afford to bring the server down while it is backed
up. Disk imaging combined with intelligent snapshot technology gives IT administrators the ability to take
backups while the server is running and without interrupting users, applications, or server processes.

Desired Solution
Get a reliable backup of the server any time during the day or night and without causing any downtime.

How can VBus Help?
VBus allows IT administrators to take live backups of their servers without causing any downtime.
VBus takes an image including the operating system, critical data and configuration settings for that
server. VBus also allows the IT administrator to set a schedule for the server to be automatically
backed up with no intervention.

VBus Use Case 3
Constant State Backup Image
Many companies make daily backups but still feel they need to have a backup of their servers when
everything is closed to ensure the likelihood of their backup is recoverable. Some companies take their
servers down at off peak times and take an image of their servers. This can take a lot of time and be very
costly for the company, but the IT administrator feels confident in the case of a disaster, the server can be
recovered with this perfect backup.

Desired Solution
IT administrators want the most reliable and recoverable backup possible but do not want the extended
downtime associated with these offline backup methods. They also want their backups to be as close to
real time as possible.

How can VBus Help?
VBus provides the ability to take an Constant State backup image for the most reliable backup
available and with the least amount of downtime. VBus takes a snapshot of the system at first start,
then every 15 minutes the system is looking for incremental backups made at the bit level (the 1s and 0s
of the hard drives). This method is repeated every 48-72 hours. Every 15 minutes, data is in a constant
state of backup, in comparison to the once a day method. The best part No Downtime is needed for
these backups. This Constant State backup image allows IT administrators the best of both worlds; the
most reliable backup and the least amount of downtime.

VBus Use Case 4
Individual File and Folder Restore
Restoring individual files and folders from tape can be a disaster. It takes a lot of time to locate the tape
media if it is not onsite, and often times the backup was never successful. Most restores that occur in the
enterprise are files and folders users accidentally deleted or overwrote. This process needs to be simple
and fast so end users can be productive.

Desired Solution
Restore individual files and folders in the least amount of time possible. This process needs to be
extremely easy and in some cases it would be even better if the end user could select what files and
folders they need and recover them without any intervention from an IT administrator.

How can VBus Help?
VBus allows the IT administrator to mount backup images and assign the image a drive letter. Since
the backups are disk based and stored on our VBus unit onsite, the process is very fast and easy and
uses Windows Explorer which end users are used to. The IT administrator can mount a backup image
and share this with an end user who can select the files and folders they need to restore. If the backup is
greater than 48-72 hours, the IT administrators can log onto the online storage and restore files or folders
as needed.

VBus Use Case 5
Update an Existing Image
Many backup imaging products in the market today allow images to be taken and then mounted for easy
access. The problem is these images are read-only files. Often times IT administrators need to update a
single driver or an existing backup contains a virus which needs to be cleaned before restoring. Since the
images are read-only, they must clean the virus or make the update, and then take another image before
they restore. This method is not efficient and can cost money and time.

Desired Solution
IT administrators want the ability to update an existing image file. The backup image files should be readwrite
and not just read-only images.

How can VBus Help?
VBus Server creates images that can be mounted as read-only or read-write. In the case of a virus, the
virus can be cleaned and the image file updated before restoring that image file to a server. Another
example is to mount an image file for an end user who has lost some data. The user can use this
mounted volume and work as normal. The changes made to that volume can be written to that backup
image as an update.

VBus Use Case 6
Create Full and Incremental Backups
IT administrators need the ability to take full backups and more importantly incremental backups to save
time and space. Many solutions use a file bases approach which means if a file is changed after a full
backup has been taken, that entire file will be backed up in the incremental. Sector based incremental
backup is the quickest and most efficient way to take an incremental backup.

Desired Solution
Once a full backup has been taken, IT administrators would like to take incremental backups from that
point forward until the next full backup. The incremental backups must be fast and take up the least
amount of disk space.

How can VBus Help?
VBus Server incremental backups are sector based. This allows backup of just the pieces of a sector
that have changed to be backup up and not the entire file. For example, if a user made a change to a
Word document that was 4MB in size, with other file based backup products, the entire 4MB file would be
backed up. With VBus and sector tracking, just the changed sectors would be backed up and not the
entire file.
