Answer 1

Answer:

Tertiary storage comprises high-capacity data archives designed to incorporate vast numbers of removable media, such as tapes or optical discs. The removable media are normally not stored in suitable drives but held in specially arranged retention slots, shelves, or carousels in an offline state. A tertiary storage platform may be perceived as a specialized type of NAS that uses additional robotic mechanisms to transfer media between their long-term storage locations and available drives without human intervention. To fulfill a client access request, a separate database that maintains the catalogue of archive contents must be consulted. As the tape library or optical jukebox cannot handle a large number of concurrent requests (there is only a limited number of tape or optical drives which operate at nominal data rates per device), the archive contents are typically copied to a data cache, for example a regular NAS server. Clients may then access the data at high speeds and possibly in parallel. The retrieved content is retained in the cache for as long as it is needed or until it is retired as an effect of the application of relevant data retention policies.

Answer 2

The most widely used tertiary data storage is the Optical discs.

• Tertiary data storage is the lowest category and is usually used for storing huge data sets.
• The information that is rarely accessed, and does not require humans to carry out operations comprises this level.
• It is slower than USB, pen drives but can perform online quickly.
• Optical discs, Tape libraries, Jukeboxes are all used to archive data.
