Glossary

Backup set

A group of backups to which an individual retention rule can be applied.

For the Custom backup scheme, the backup sets correspond to the backup methods (Full, Differential, and Incremental).

In all other cases, the backup sets are Monthly, Daily, Weekly, and Hourly.

Cloud server

[Disaster Recovery] General reference to a recovery or a primary server.

Cloud site (or DR site)

[Disaster Recovery] Remote site hosted in the cloud and used for running recovery infrastructure, in case of a disaster.

Differential backup

A differential backup stores changes to the data against the latest full backup. You need access to the corresponding full backup to recover the data from a differential backup.

Failback

Switching a workload from a spare server (such as a virtual machine replica or a recovery server running in the cloud) back to the production server.

Failover

Switching a workload from a production server to a spare server (such as a virtual machine replica or a recovery server running in the cloud).

Finalization

The operation that makes a temporary virtual machine that is running from a backup into a permanent virtual machine. Physically, this means recovering all of the virtual machine disks, along with the changes that occurred while the machine was running, to the datastore that stores these changes.

Full backup

A self-sufficient backup containing all data chosen for backup. You do not need access to any other backup to recover the data from a full backup.

Incremental backup

A backup that stores changes to the data against the latest backup. You need access to other backups to recover data from an incremental backup.

Local site

[Disaster Recovery] The local infrastructure deployed on your company's premises.

Module

Module is a part of protection plan providing a particular data protection functionality, for example, the backup module, the Antivirus & Antimalware protection module, and so on.

Physical machine

A machine that is backed up by an agent installed in the operating system.

Point-to-site (P2S) connection

[Disaster Recovery] A secure VPN connection from outside to the cloud and local sites by using your endpoint devices (such as a computer or laptop).

Primary server

[Disaster Recovery] A virtual machine that does not have a linked machine on the local site (such as a recovery server). Primary servers are used for protecting an application or running various auxiliary services (such as a web server).

Production network

[Disaster Recovery] The internal network extended by means of a VPN tunneling and covering both local and cloud sites. Local servers and cloud servers can communicate with each other in the production network.

Protection agent

Protection agent is the agent to be installed on machines for data protection.

Protection plan

Protection plan is a plan that combines the data protection modules including

Public IP address

[Disaster Recovery] An IP address that is needed to make cloud servers available from the Internet.

Recovery point objective (RPO)

[Disaster Recovery] Amount of data lost from outage, measured as the amount of time from a planned outage or disaster event.

RPO threshold defines the maximum time interval allowed between the last suitable recovery point for a failover and the current time.

Recovery server

[Disaster Recovery] A VM replica of the original machine, based on the protected server backups stored in the cloud. Recovery servers are used for switching workloads from the original servers, in case of a disaster.

Runbook

[Disaster Recovery] Planned scenario consisting of configurable steps that automate disaster recovery actions.

Single-file backup format

A backup format, in which the initial full and subsequent incremental backups are saved to a single .tibx file. This format leverages the speed of the incremental backup method, while avoiding its main disadvantage–difficult deletion of outdated backups. The software marks the blocks used by outdated backups as "free" and writes new backups to these blocks. This results in extremely fast cleanup, with minimal resource consumption.

The single-file backup format is not available when backing up to locations that do not support random-access reads and writes.

Site-to-site (S2S) connection

[Disaster Recovery] Connection extending the local network to the cloud, via a secure VPN tunnel.

Test IP address

[Disaster Recovery] An IP address that is needed in case of a test failover, to prevent duplication of the production IP address.

Test network

[Disaster Recovery] Isolated virtual network that is used to test the failover process.

Virtual machine

A virtual machine that is backed up at a hypervisor level by an external agent such as Agent for VMware or Agent for Hyper-V.

A virtual machine with an agent inside is treated as physical from the backup standpoint.

VPN appliance

[Disaster Recovery] A special virtual machine that enables connection between the local network and the cloud site via a secure VPN tunnel. The VPN appliance is deployed on the local site.

VPN gateway (formerly, VPN server or connectivity gateway)

[Disaster Recovery] A special virtual machine providing a connection between the local site and the cloud site networks via a secure VPN tunnel. The VPN gateway is deployed on the cloud site.
