Welcome to Redstor's glossary
Below you can find brief definitions of our key product terms, as well as links to articles with more detail.
An Account is a selection of data managed as a unit using our software. Multiple accounts form Groups, while multiple Groups form Collections.
The AccountServer forms part of the Storage Platform and is the part of our software that manages user authentication (e.g. passwords), updates, reporting and more.
Our Archiving service saves on disk space and storage costs by replacing redundant, obsolete and trivial (ROT) files with much smaller (“sparse”) files.
- Bare Metal Recovery (BMR)
Bare Metal Recovery is a data recovery method that entails recreating a backed-up system on a completely new physical or virtual machine, i.e. with no software or operating system components present on the machine before recovery.
- Changed block tracking (CBT)
Changed block tracking is a faster method of backing up, in which only those data blocks in the backup selection that have changed since the previous backup are scanned for changes, instead of scanning whole files.
- Control Centre
Our Control Centre is a web dashboard that enables our customers to check the status of their backups, restores, and archives from anywhere. The Control Centre also displays information such as current backup selections, files last accessed, and used space on machines.
- Data Management Agent
The Data Management Agent is a desktop application that is linked to a specific Account and is used by the customer to manage the data on that Account’s machine.
- Data verification
Our data verification functionality regularly scans all the data in each of a customer’s Accounts, checking that all the files are present and intact.
Our deduplication functionality saves time and storage space by checking that identical files are transferred into storage only once.
- Enterprise Server Edition
The Enterprise Server Edition (ESE) is the successor to our original Server Edition (SE) Data Management Agent, offering significant advantages over SE in terms of functionality and support.
- Full System Backup (FSB)
Full System Backup is a backup option offered by Redstor which automatically includes not only a selection of files, but all data and metadata on a system, including the system state (OS, installed software and updates, hot fixes, etc.). In a disaster scenario, this backup can be used to do a Full System Recovery (FSR).
The European Commission’s General Data Protection Regulation (GDPR), which aims to strengthen the protection of EU citizens’ data, and to increase their say in how their data is used.
- Group certificate
A Group certificate is a type of electronic document used by Redstor to prove the ownership of stored data and to control access to that data.
- HSM data
Hierarchical Storage Management (HSM) data consists of roll-ups that were archived before they were deleted from our Storage Platform.
Insight is Redstor's data discovery service and is used to scan the customer's data estate to reveal aggregated, actionable analytics such as the total data selected for backup, files last accessed, used space on machines, and much more.
- Incremental backups
Incremental backups is a backup method used by Redstor in which only data that has been changed or created since the previous backup is backed up.
InstantData is a trademarked Redstor technology which allows a customer to access their backed-up files almost instantaneously after triggering a recovery. This is possible because the files that are accessed first are recovered first, while the less urgent data recovery continues in the background.
Our Integrity Check feature is a reliable way of checking the integrity of your backed-up files on the relevant StorageServers and MirrorServers. All files are scanned to make sure they are present and intact.
- Local copy
Local backup copy is a Redstor feature whereby the customer’s most recent backups can be kept on a local machine in addition to on the Storage Platform, facilitating faster recovery.
- Logical volume management (LVM)
Our logical volume management LVM Snapshot feature for the Linux ESE Agent is used when a crash-consistent backup is required, for example when backing up database files that can be written to while a backup is in progress.
A MirrorServer is an optional server on the Storage Platform that contains an exact duplicate of the customer’s backups as an additional safety measure.
Profiling is a Redstor functionality that enables a customer to centrally apply specific settings (such as backup inclusions and exclusions) to all Data Management Agents in a Group.
- Server Edition
Server Edition (SE) is the predecessor to our Enterprise Server Edition (ESE) Data Management Agent. We are no longer adding new functionality to the SE version of the software.
- Snapshot backup
A Snapshot is a point-in-time copy of all your data which can be used as a seed (initial) backup (for example, onto external media) to save on transfer costs and allow business operations to continue while the first full backup is completed. (Not to be confused with VSS snapshots.)
- Staged backup
Staged backup is a backup method used by our ESE Data Management Agent in which the customer’s data is written to temporary storage before it is transferred to the Storage Platform. This enables uninterrupted backups, but results in greater disk usage.
- Storage Platform
The Storage Platform forms part of our software and consists of the AccountServer, where our customers’ account information is stored, and the StorageServers (and MirrorServers), where their data is stored.
- Storage Platform Console
The Storage Platform Console is the user interface of our Storage Platform and is accessed by the customer’s data administrator as part of the data management process, e.g. to add, rename or delete Groups or Collections, or read backup reports.
StorageServers form part of the Storage Platform, and house our customers’ backed-up data.
- Streaming backup
Streaming backup is a backup method used by our SE Data Management Agent in which the customer’s data is transferred to the Storage Platform without being written to temporary storage first. This method is faster than staged backup and uses less disk space, but is severely limited in terms of customisation.
- Stub file
A stub is a very small (“sparse”) file that represents an original file which is stored in a different location. When a stub is accessed, its original file’s data is immediately accessible through a process called rehydration.
- System state backup
A system state backup is a backup of the files that a system needs in order to function, such as the boot files and the registry.
- VSS snapshot
A Volume Shadow Copy Service (VSS) snapshot is a point-in-time copy of all your files that can be made even while these files are in use. VSS is unique to Microsoft Windows.
