2. Computer data storage - Wikipedia

   en.wikipedia.org/wiki/Computer_data_storage

   Off-line storage is computer data storage on a medium or a device that is not under the control of a processing unit. [9] The medium is recorded, usually in a secondary or tertiary storage device, and then physically removed or disconnected. It must be inserted or connected by a human operator before a computer can access it again.

3. Tape drive - Wikipedia

   en.wikipedia.org/wiki/Tape_drive

   A tape drive is a data storage device that reads and writes data on a magnetic tape. Magnetic-tape data storage is typically used for offline, archival data storage. Tape media generally has a favorable unit cost and long archival stability. A tape drive provides sequential access storage, unlike a hard disk drive, which provides direct access ...

   The backup data needs to be stored, requiring a backup rotation scheme, [4] which is a system of backing up data to computer media that limits the number of backups of different dates retained separately, by appropriate re-use of the data storage media by overwriting of backups no longer needed. The scheme determines how and when each piece of ...

6. Magnetic-tape data storage - Wikipedia

   The device that performs the writing or reading of data is called a tape drive. Autoloaders and tape libraries are often used to automate cartridge handling and exchange. Compatibility was important to enable transferring data. Tape data storage [2] is now used more for system backup, [3] data archive and data exchange. The low cost of tape has ...

   Network-attached storage (NAS) is a file-level computer data storage server connected to a computer network providing data access to a heterogeneous group of clients. In this context, the term "NAS" can refer to both the technology and systems involved, or a specialized computer appliance device unit built for such functionality – a NAS ...

8. Digital Data Storage - Wikipedia

   en.wikipedia.org/wiki/Digital_Data_Storage

   Digital Data Storage (DDS) is a computer data storage technology that is based upon the Digital Audio Tape (DAT) format that was developed during the 1980s. DDS is primarily intended for use as off-line storage, especially for generating backup copies of working data.

9. Disk-based backup - Wikipedia

   en.wikipedia.org/wiki/Disk-based_backup

   Disk-based backup refers to technology that allows one to back up large amounts of data to a disk storage unit. It is often supplemented by tape drives for data archival or replication to another facility for disaster recovery. Backup-to-disk is a popular in enterprise use for both technical and business reasons.
