A

Archiving

Data archiving is the storage of important but unexploited data on a medium other than the production system. Archived data is often legal or evidential data.

Appliance

A physical or virtual computer machine with a distinct function within the IS. In our case the apliances are intended to execute backups.

B

Backup agent

The agent is the program installed in a machine (server or workstation) to back up files of this host machine. It reads the files and transfers all or part of the modified data to the backup target. It also allows the file to be reconstructed on this machine in the recovery process.

Backup Engine

The backup engine is the software component that controls, reads, saves and sorts backups in one or more databases.

Backup logs

Backup logs record all the backup attempts made for a backup job.

Backup range

The backup range is the period of time, often defined by the user, during which the system can perform backup operations.

Backup report

The backup report gives the backup status at a time T for each machine and/or source directory.

Backup target

The backup target is the storage space intended to receive the data to be backed up.

Byte

Computer memory unit equal to 8 bits.

C

Cloud-to-box

Feature that allows data operated on third party or cloud services to be backed up to a physical appliance on premise.

Configuration report

The configuration of a software is the set of parameters defined by the user during its installation. The configuration report is the report of all these parameters.

Cyber-resilience

Cyber-resilience represents all the means a company has to protect the data it uses and stores. To cope with the cyber risks to which it is exposed, these means can be multiple: detection of attacks, data encryption, isolation of backup files, etc...

D

Datacenter

A datacenter is a physical infrastructure, with enhanced security standards, where many machines (server racks) that can store a large amount of data are grouped together.

Data encryption

Data encryption consists of protecting data using an algorithm to make it unreadable by a third party, to protect it from misuse.

Data outsourcing

Data outsourcing is the operation whereby data is copied and stored off-site on a cloud space.

Data volume

In computing, a volume is a storage area with a file system. A volume is typically placed on a partition of a hard disk.

Deduplication

In computing, deduplication is a storage technique that consists of factoring identical data sequences in order to optimise the storage space used.

Delta-bloc

A backup method that only takes into account file increments that have been modified within a defined time frame. This technique reduces storage space and reduces backup execution time.

Differential backup

This method consists of saving a first full backup and then all the changes read from this first full backup. This method allows a shorter restore time but consumes more storage space.

Distributed storage

Data storage technology that consists of fragmenting data to distribute it over the available space of an existing infrastructure. In the event of an incident these fragments are reconstructed.

E

Endpoint security

Endpoint security focus on user device predictive protection in order to detect and block attacks threatening the organization network.

F

Fireproof box

The fireproof backup box is a fire-resistant computer hardware. In our case, the Fireprooof box is used to protect the hard disks it contains in the event of a disaster.

F.I.R.S.T.

French Industrials for Resilience, Security & Trust. The F.I.R.S.T. association (French Industrials for Resilience, Security & Trust) brings together innovative SMEs in the cybersecurity industry which have decided to work together.

Fragmentation

In a distributed storage process, fragmentation means the division of data and its distribution over the available storage spaces of the same infrastructure.

Full backup

This backup method consists of backing up all files and folders on the system in their entirety at a given time T. An additional full copy of the data source is stored with each backup, which consumes a significant amount of storage space. Care must therefore be taken to limit the number of backups to be kept.

G

GBS ou GBPS

Gigabytes (gigabits in French) per second.

Georedundated

The data are georedundated when they are duplicated on 2 separate geographical sites in case the primary system is not able to access the data.

Granular (restoration)

Granular recovery allows the user to select the data to be recovered as a priority in order to optimise disaster recovery.

H

Historisation

Data archiving is a parameter setting that allows different versions of a file to be kept during its evolution and within the limit of the defined anteriority, in order to be able to restore the desired version.

Hybrid Cloud

The hybrid cloud can combine private and public clouds for greater flexibility according to the constraints imposed by a company's IS.

I

Incremental backup

This method saves only the changes from the previous version. This method requires a longer restore time but less storage space.

Infrastructure

All of a company's physical and virtual IT equipment.

J

Job

A job is a preconfigured task wihch defines how, where and when the data will be saved by the backup software.

K

Kbps

Kilobits per second

L

LTO

Linear Tape-Open (or LTO) is an open-format magnetic tape storage technique.

M

Mbit/s ou Mbps

Mégabits per second.

N

O

Object storage

A non-hierarchical storage method commonly used for cloud storage. It consists of storing data in units called objects.

On-premise

On-premise literally means "on-premise", so we speak of a private cloud on-premise when it is deployed on the premises of the user entity, and off-premise when it is hosted off-site.

P

P2V

Physical To Virtual (P2V) is a process of migrating the operating system, applications and data from a physical server to a virtual machine hosted on a virtualized platform (virtualization).

Peer-to-peer (P2P)

Peer-to-peer in French. This is a system where several networked machines can both receive and distribute data without a centralized server.

POSIX storage

POSIX is a family of technical standards defined since 1988 by the Institute of Electrical and Electronics Engineers (IEEE), and formally referred to as IEEE 1003. These standards emerged from a project to standardise the programming interfaces of software intended to run on variants of the UNIX kernel.

Q

Quota

Backup volume allocated per contract.

R

Rack

This is a rack or metal cabinet with drawers but generally with slides (or rails) located in the computer cases and servers, used to accommodate standard size hard disks (2.5 or 3.5 inches).

Raid

Computer RAID, or Redundant Array of Independent Disks, is a technology for distributing storage among multiple hard disks. There are several levels of RAID, the most common are RAID 0, RAID 1 and RAID 5. These levels can be combined with each other.

Ransomware

Rançongiciel in French. Ransomware is malicious software that encrypts data and renders it inaccessible, with the aim of forcing the user to pay to retrieve it.

Remote administration

Remote administration is a program that allows a third party system to be controlled via a remote connection.

RTO Recovery time objective

Data storage technology that consists of adding hardware to an existing storage infrastructure to increase storage capacity in a scalable and almost infinite manner.

Shadow IT

Shadow IT refers to IT operations within organisations carried out without the approval of the information systems management.

SDS

Abbreviation for software-defined storage, which refers to data storage based on software solutions. Software solutions enable more intelligent management of data storage.

Snapshot

In a backup system, a snapshot is the capture of data from a volume at a given time. Concretely, it is a reference set for all the modifications made since the last snapshot. The snapshot is therefore dependent on the source data and cannot be substituted for a backup system.

Source

A backup source is any appliance, workstation or cloud service where the data to be backed up is produced or stored.

Storage node

A storage bay component.

Synchronization

File synchronisation is the process of matching content produced in several different locations instantaneously.

Synthetic backup

It combines full and incremental backup methods. In fact, the server produces backups that are complete from the first backup combined with the data from the incremental backups.

T
