{anchor:glossary_glossary_htm_block_tran_4652}
...Block Transfer Protocol is the IP-based high performance network protocol used for transferring Backup and Restore data. The BTP service runs on port 1167 and uses TCP. Because BTP uses TCP/IP, it can transfer data between any two (2) computers on the Internet. BTP is highly secure and uses RSA Keys for authentication. All BTP protocol traffic is encrypted using RSA Keys and a Blowfish cipher. Block data (payload) may or may not be encrypted depending on User options.

{anchor:glossary_glossary_htm_cdp_agent}
...CDP Agent is a part of the Continuous Data Protection solution. It is the service or daemon that runs on a computer being backed up by R1Soft. CDP Agents can be installed on Linux or Windows. Installing a CDP (Backup) Agent is required to take Backups of a computer or Restore files. The CDP Agent accepts Backup and Restore requests from CDP Servers. Righteous Backup is licensed based on the number of purchased CDP (Backup) Agents.

{anchor:glossary_glossary_htm_cdp_server}
...CDP Server is a part of the Continuous Data Protection solution - the computer running R1Soft CDP Server software. A server may be Stand Alone or a Node that is part of a Data Center Cluster. In the Stand Alone version, the CDP Server provides a Web Interface for management, a Task scheduler to process scheduled Backup jobs, and makes requests to CDP Agents to initiate Backup or Restore jobs. CDP Server licenses are free with purchase of CDP Agents.

...The Control Server is the central controller in a deployment of CDP Server For Data Centers. There may only be one (1) Control Server for each installation of CDP Server For Data Centers. The Control Server houses the database of Hosts and their Backup jobs. It also controls each Node in the Cluster and batches out Backup jobs to available [CDP Servers|#glossary_glossary_htm_cdp_server].

{anchor:glossary_glossary_htm_compressio_3261}
...Data compression is the process of encoding information using fewer bits than an un-encoded representation would use through use of specific encoding schemes. Disk Safes use zlib also known as gzip compatible compression and are capable of delivering about a 2:1 compression ratio for most environments. Compression is performed at the hard Disk sector level on the Host during a Backup by the CDP Agent. The compressed Disk sectors are sent over the network and stored in its compressed form in the Disk Safe. Compression can be used on its own or in combination with encryption.

{anchor:glossary_glossary_htm_data_cente_1547}
...Data Center is a cluster which can consist of one Control Server and one or several connected CDP Servers and Web Servers. The Control Server houses the database of Hosts and their Backup jobs. It also controls each Node (CDP Servers and Web Servers) in the Cluster and batches out Backup jobs to available CDP Servers. The location of the server and the CDP Server that processes Backups is completely invisible. The advantages of Data Center solution over a stand-alone Backup Server are that user interface requests go to a dedicated server and are not slowed down by the Backup Servers which are busy processing backup and restore jobs.

h5. Defragmentation
h5. Defragmentation
Defragmentation shrinks the unused space in your Disk space freed by deleting or rotating out unwanted Incremental Backups to reduce the Disk usage. The contents of the Disk are physically reorganized to store the pieces of each file close together and contiguously. Much like defragmenting a hard Disk, defragmenting or shrinking the Disk Safe can involve relocating data. Typically, Disk Safes never need to be defragmented as Data Storage usually increases with time. When a Host reduces its Disk usage substantially, defragmenting is typically required.\\
{note:title=Notice} Due to the change in caching techniques in CDP Server 2x, keeping your Disk Safe defragmented is now of greater importance. The default for the new 2x version installation is 0% (no limit). It is recommended that you set this option to 0% as it will allow you to configure Disk Safes to reduce fragmentation as much as possible.{note}

{anchor:glossary_glossary_htm_disk_recov_8519}
...Disk Recovery Point or Recovery Point is backed up data created by one (1) Backup Task. Righteous Software delivers fast access to any Recovery Point as if it were a complete Disk Image with performance comparable to the native file system. Disk Safes allow any Recovery Point to be deleted, freeing up the Disk space consumed by the Recovery Point, while still maintaining the dependent sectors used by other Recovery Points.

{anchor:glossary_glossary_htm_disk_safe}
...Data on the CDP Server is stored in Righteous Software's patent-pending Disk Safe storage format. This on-disk format enables the CDP Server to archive point-in-time recovery images for long periods of time using as little Disk space as possible. Scheduled point-in-time Volume snapshots are scheduled on the CDP Server. The CDP Server then periodically connects to the CDP Agent program and synchronizes changed Disk sectors to the CDP Server. The CDP Server creates a new point-in-time image of the Disk Volume every time it connects to the Agent for synchronization. The point-in-time images are called Recovery Points and are stored in a Disk Safe.

{anchor:glossary_glossary_htm_encryption}
...Encryption is the process of transforming information to make it unreadable to anyone except those possessing special knowledge, usually referred to as a Key. CDP Server supports strong encryption of Disk data using RSA Keys and the Blowfish cipher. During a synchronization, data is encrypted (and optionally compressed) on the Agent and sent to the Server over the network where it is stored in encrypted form. The data can only be decrypted using a RSA Key protected with a passphrase. During a Bare-Metal Restore, Disk sectors are decrypted on the fly at the CDP Agent.
