| Bare-Metal Disaster Recovery |
The ability of a backup and restore system to restore a computer system to a previous state directly to a new unformatted hard disk or disks.
To qualify as bare-metal disaster recovery, a backup system must restore all of the following: disk formatting, partition tables, Master Boot Record, Operating System and user files. |
| Block Transfer Protocol (BTP) |
Block Transfer Protocol. This 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 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. |
| CDP Agent |
The service or daemon that runs on a computer being backed-up by R1Soft. Installing a Backup Agent is required to take backups of a computer or restore files. The Backup Agent accepts backup and restore requests from Backup Servers.
The R1Soft bare-metal disaster recovery CDs and PXE boot media run a copy of the CDP Agent.
Righteous Backup is licensed based on the number of purchased Backup Agents and Backup Servers. |
| CDP Server |
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 Backup 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. |
| Control Server |
The central controller in a deployment of CDP Server for Data Centers. There may only be one 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. |
| Defragmentation |
Defragmentation shrinks the unused space in your disk space freed by deleting or rotating out unwanted incremental backups to reduce the disk usage. It does this by physically reorganizing the contents of the disk 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 in the Disk Safe. Typically, Disk Safes never need to be defragmented as data storage usually increases with time. What typically requires defragmenting, a Disk Safe will store when a Host reduces its disk usage substantially.
Device |
| Device |
A device is a partition on a Host eligible for Backups. For example on a Linux host a device might look like “/dev/sda1”. |
| Disk |
A Disk is a directory or path for storing backup data made available to a CDP Server. For example a Disk’s path might look like “E:\backup-data” or a network path like \\nas-device\share |
| Disk Safe |
Data on the CDP Server is stored in R1Soft’s patent-pending Disk Safe storage format. This on disk format enables CDP Server to archive point-in-time recover 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. |
| Disk Safe Browser |
The Disk Safe Browser allows you to browse your Disk Safes, Devices, and backup images in a file system tree. This is also where you initiate Bare-Metal Restores or select combinations of files and directories to restore. |
| 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 Agent. |
| Host |
A Host is a computer running a CDP Agent. A Host is any computer that is being backed up by a CDP Server and could be a desktop PC or a “server”. |
| Host Administrator / Host Admin |
By adding Administrators to Hosts you can control who can access Hosts in the Backup System and what their level of permissions are. |
| Host Discovery |
The process of adding a new CDP Agent to a CDP Server. During this process a CDP Agent’s RSA public key is stored on the server. A Host’s physical partitions or Devices are also automatically discovered during this task and the partition table is imported into the CDP Server. |
| Incremental Backup |
An incremental backup is a backup method where multiple backups are kept (not just the last one). These backups will be incremental if each original piece of backed up information is stored only once. Then successive backups only contain the information that changed since a previous backup.
|
| Linux CDP Agent |
A CDP Agent (see CDP Agent) that runs on the Linux operating system. |
| Partition Table |
Partition Table is a placeholder for the description of a Partition on the hard disk. The Partitions are specific areas within the disk. During Bare-Metal Restore, Partition Table Restore Task must be run in order to recreate a Partition table which includes entries for the recovered file systems. |
| Quota |
Quotas can optionally be set for Volumes and Hosts limiting the disk usage of them. A Host level quota applies to all data storage used by that Host including all of that Host’s Disk Safes. When a quota is reached, the Backup job will be interrupted and fail. Volume quota applies to all Hosts and Disk Safes assigned to the Volume. |
| Recovery Point / Incremental Disk Image / Incremental |
A point-in-time snapshot of your one or more disk volumes on a Host. Recovery points are incremental and only disk blocks changed since the last synchronization (backup) are stored. A recovery point works as if it is a complete disk image using the Disk Safe to maintain state among block dependencies across a large number of incremental backups. |
| Rotation Policy |
Each scheduled Backup Task can have an associated Rotation Policy. When defining a Backup Task, you can specify how many Incrementals to keep. The Rotation Policy Task will look at all other incremental backups created by the same scheduled task and delete the oldest Incrementals until only the last X Incrementals remain as defined in the Backup Task. |
| RSA key |
RSA is an algorithm for public-key cryptography. The letters RSA are the surname initials of the scientists who publicly described it in 1977. Authentication between the CDP Agent and Backup Server is controlled using RSA keys. The RSA key and backup key are used when encryption is enabled. |
| Storage Pool |
A collection of Disks used for storing the backup data for one or more Volumes. Storage Pools consist of one or more Disks where the data is actually stored. You can increase the capacity of a Storage Pool by adding more Disks to it. |
| Super User |
Super Users do not have restricted rights. Super Users always have the right to add new Users and Hosts into the system. Super Users can view and administer all Users and Hosts. Super Users are always allowed to change their password. |
| Task |
Each operation that is fulfilled by a User or by the system is called a Task. You can check the status of the Tasks on the Global or Host Task History page. The Task Scheduler screen allows you to view and manage the Scheduled Tasks. |
| Task History |
Most work performed by the CDP Server is done as a background or scheduled Task. The status and log record for each Task is available for browsing via the "Task History" page. There are two Task History pages: Host Task History and Global Task History. |
| Task Scheduler |
The “Task Scheduler” is a web interface to manage once Tasks are created. The actions include: run, edit, and disable. |
| User Administrator / User Admin |
Administrator role means a possibility to administrate other User accounts within the system including: viewing Users list, editing User account properties, and deleting User accounts from the system. |
| Volume |
Backups for one or more servers are stored on a Volume. Volumes can be given a quota to limit its capacity for storing backup data. A Volume can be assigned to one or more users. You can also limit the number of host’s a user is allowed to add to a volume. A Volume’s data is stored on a Storage Pool and a Volume must be assigned to a single Storage Pool. |
| Windows CDP Agent |
A CDP Agent (see CDP Agent) that runs on the Windows operating system. |
