Block Level Backups
A NAS must be placed at each location with a Windows 2000 or 2003 server on a LAN.  Multiple NAS's can be placed on the same LAN.  Each selected Server must be completely imaged. Individual files can not be added or omitted from the back up.  Our solution is a block level backup where we are capturing the entire volume of a server at the 1's and 0's level.  Block level data is raw data which does not have a file structure imposed on it.

The block-level image is an exact digital duplicate of the on-site server.  Database applications such as Microsoft SQL Server and Microsoft Exchange Server transfer data in blocks without having to worry about files being open or being used.  Block transfer is the most efficient way to write to disk. This technology allows for complete server restorations using last functioning server system state before the failure occurred.  Frequency of off-site back ups is limited by the amount of available bandwidth at the client site.

Security
Encryption is an important step in the process of transmitting data between the NAS and the remote sites because it greatly reduces the risk of data loss incidents that plague magnetic tape and prevents man-in-the-middle attacks during transmission. We employ the 256-bit Advanced Encryption Standard (AES) algorithm to encrypt the backup images before they are saved on the NAS.

After imaging the servers to which it is attached, the NAS device creates an independent 256-bit encrypted tunnel and transmits the imaged data to a secure offsite location where it resides in an encrypted, compressed format. That remote site then replicates again to an alternate data center, creating a total of three copies of the data in three geographically distinct regions.  The data is encrypted and we do not have access to the data on the NAS or either of the remote storage facilities.

Smart Data Transport
Data transmission itself occurs over your client's internet connection and can easily be configured to minimize bandwidth consumption. Our NAS leverages Adaptive Bandwidth Throttling, which allows us to set a limit on outbound bandwidth used. (E.g. assuming the customer has a 768Kpbs outbound connection, adaptive bandwidth throttling can be set with a maximum at 512Kpbs). We can therefore exercise fine control over the data imaging and transmission processes.

We perform packet level verification along with rate adaptive bandwidth throttling. The result is that we can send very large files over the internet without affecting outbound data rates. Additionally, we send data over a secure AES 256-bit encrypted UDP session, which provides significant efficiencies in data transport speeds. If the connection drops at any time the transmission picks up from the last successful packet received. This is a vast improvement over other technologies that use ftp transmission where a connectivity problem results in the entire amount of data needing to be resent.

On-site and Off-site Solution with Multi-year Archiving
Each NAS device, depending on the model, can be configured to backup from one single server up to eight servers.  Multiple NAS devices can be placed on a LAN. As each backup occurs the data is securely transferred to the off-site colocation facility so in the event of a complete disaster we are able to ship a new NAS device imaged with the latest client data. Data is transferred to the colocation facility using AES 256-bit encryption and band-throttling software.

Multi-year archiving using a combination of daily and monthly synthetic images is set up on the NAS Device and then replicated to the off-site colocation facility.

Recovery after a Catastrophe
In the event of catastrophe (such as a natural disaster or fire), you order a new NAS that will be imaged and sent out next-day business air at the additional cost specified on the pricing page. Depending on the NAS Model, multiple servers can be virtualized on one NAS while the NAS can also continue to perform backups. Your client's data will not be hosted at the collocation facility.

Near-line Disaster Recovery and a Standby Server Using Virtualization
The NAS comes with built-in virtualization software. This allows a server which has failed to be restored on the NAS as a virtual image giving the customer a standby server in less than hour (in most cases - data on restore speeds are in a table below).

Since the total image of the server is being restored no configuration changes are needed as the virtual image has the same properties, IP address, NetBIOS name as the failed server and backups continue to happen even when running the virtual image. When new hardware/spares arrive, the virtual image can be shutdown and the latest backup image can be used to perform a bare metal install on the new hardware.

Disaster Recovery Costs
In a disaster, where a client loses his entire office, servers and on-site NAS included, you order a newly imaged NAS, with the most current backup, to be shipped out via next-business day air transportation to a location of your choice.  Bear in mind that the frequency of off-site back ups is limited by the amount of available bandwidth at the client site. Limited bandwidth will result in transmission periods which means back ups may only be done hourly or daily depending on the speeds available. It's important to be cognizant of the backup frequency at each of your client sites and greater bandwidth may make good business sense.

When the NAS arrives, all our Field Engineer need to do is plug in the RJ-45 cable and you're up and running. The cost for this "recovery service" will be $250 plus all freight and shipment costs. This will allow you to use the NAS for 2 weeks before it must be returned, at your expense.

This will allow you to get a new server ordered and in place and do a "bare metal restore" from the NAS before returning the NAS if you so desire.  Alternatively you can choose to keep the NAS and you will be billed for the list price of the new NAS. This would also allow you to use this NAS for the ongoing backup and remote storage when you move forward setting up your new infrastructure.

Be aware, if this event occurs we will not host the data at the collocation facility. This is done because we do not want or have access to the data, for security purposes.

Offsite Remote Storage
Stored at two XO high availability data centers in Phoenix and Baltimore.    

• Highly redundant storage with backup images stored at the data centers on a SAN at the primary facility, then replicated to the secondary facility.
• Connectivity provided by multiple providers with automatic failover capabilities.
• Facilities provide two fiber optic network drops for our backbone.
• Full physical security at each facility including security cameras, key card and biometric access.
• Network is secured with high-end redundant, automatic failover firewalls.
• Fire suppression and environmental control provided.
• Automatic back up power provided by on site generators.
• Your data is never hosted at the collocation facility. This is done because we do not want or have access to the data, for security purposes.
• Verification tests are done to point out any data corruption. In the event this occurs, the NOC takes the steps to fix the corruption or re-image a completely new image should the corruption be irreparable.
• Off-Site Storage is available by the GB
