Netmail Store object storage for your email archives

Netmail Store is a CAS technology (CAS as in Content Addressed Storage). The archived document is identified by a unique 128-bit identifier known only to Netmail Archive or Netmail Detach.

Netmail Store automatically manages email security copy(s)

When it come to setting up Netmail Store, the administrator can decide the number of security copies he wants:1 or 2. Thus an archived document is managed by Netmail Store in 2 or 3 copies. Netmail Store has a mechanism that constantly checks the number of copies. If, at any given time, a copy is missing, Netmail Store autonomously rebuilds the missing copy from the existing document(s).

Netmail Store organizes the different copies of the document in order to reduce risks. Copies of the same document are put on different servers and on different disks. If you choose to manage each archived document in duplicate, it is recommended to use two Netmail Store nodes. If you choose to manage each archived document in triplicate, you should use three Netmail Store nodes.

In this manner, the organization does not need to set up a backup solution for data archived by Netmail Archive and stored by Netmail Store.

Netmail Store manages a remote replica

Netmail Store has a router that can remotely create a replica of archived data. The organization is completely protected in case of a major disaster (data center fire, flood, etc.).

Netmail Store is a selfmanaged solution

Netmail Store is a solution that manages itself
Depending on the conservation policies chosen, storage needs to be increased regularly. This manipulation is extremely simple with Netmail Store. Simply add a disk to the server or simply add a server in the storage cluster. Netmail Store will automatically realize that it has more space available and immediately begin to distribute the data to reduce the load of servers and to limit the risk of data loss.

Netmail Store is very quick to set up and easy to administer

Netmail Store is a software based on a Linux kernel that does not require any OS or any additional software. To install Netmail Store, all you need is an x86 server with disks and connected to the network. Netmail Store is installed by a simple reboot from a USB key.

Netmail Store also includes a management console called Cluster Services Node (CSN) that allows you to group the management of all Netmail Store nodes on a single VM. CSN also avoids the need to use a USB key: each Netmail Store node retrieves the image of the VM from CSN.

Netmail Store guarantees the integrity of archived data

Netmail Store is a WORM: Write Once Read Many technology that prohibits any modification of the document. An archived email contains all the information that the original email contained at the time of its archiving (body of the message, metadata and attachments).

Netmail Store prohibits unauthorized access

Netmail Store is a CAS technology: the solution does not use a File System. So it is not possible for a administrator to browse stored objects. The only way to get a document for a computer scientist would be to program a “get”. Yet he would have to know the unique identifier of the document needed. Netmail Store is a place of storage whose access is completely secured (security by obscurity) and which forbids, in fact, any unauthorized access by Netmail Archive.

Indeed, the only way to access the archived document is to use Netmail Archive. The user must identify himself and any action on an archive (reading, transfer, printing, annotation ..) is recorded.

Netmail Store is a scalable system

The solution can theoretically handle several hundred petabytes (PB) without any worries.

On the other hand, since the Netmail Store does not organize documents into File Systems, there is no problem with the number of documents that can be stored. For large organizations that archive a lot of emails over a very long time, they may be coming to the limits of File Systems for the number of files to manage.

Netmail Store is a thrifty solution

The price of Netmail Store depends only on the number of BALs processed and not the amount of data stored.

Netmail Store is not necessarily required

Netmail Archive can work without Netmail Store. Netmail Archive can use any storage solution based on the CIFS protocol.
