Schemes for data retention do not make provisions for adequate regulation of the data retention process and for independent judicial oversight. [citation needed] Data retention is an invasion of privacy and a disproportionate response to the threat of terrorism. [citation needed] It is easy for terrorists to avoid having their communications ...
Data remanence is the residual representation of digital data that remains even after attempts have been made to remove or erase the data. This residue may result from data being left intact by a nominal file deletion operation, by reformatting of storage media that does not remove data previously written to the media, or through physical properties of the storage media that allow previously ...
Data holdings are generally the storage methods used in the past when data has been lost due to environmental and other historical disasters. [4] Furthermore, data retention differs from data preservation in the sense that by definition, to retain an object (data) is to hold or keep possession or use of the object. [7]
Magnetic, or ferrite core, data retention is dependent on the magnetic properties of iron and its compounds. PROM, or programmable read-only memory, stores data in a fixed form during the manufacturing process, with data retention dependent on the life expectancy of the device itself.
The scheme determines how and when each piece of removable storage is used for a backup job and how long it is retained once it has backup data stored on it. Different techniques have evolved over time to balance data retention and restoration needs with the cost of extra data storage media. Such a scheme can be quite complicated if it takes ...
Examples of these are birth, death, medical/health, and educational records. e-Science , for example, is an area where ILM has become relevant. In 2004, the Storage Networking Industry Association , on behalf of the information technology (IT) and information storage industries, attempted to assign a new and broader definition to Information ...
Bitstream copying (or data backup) is a foundational operation often employed before many other practices, and facilitates establishing the redundancy of multiple storage locations: refreshing is the transportation of unchanging data, frequently between identical or functionally similar storage formats, while migration converts the format or ...
The Data Retention Directive (Directive 2006/24/EC), later declared invalid by the European Court of Justice, was at first passed on 15 March 2006 and regulated data retention, where data has been generated or processed in connection with the provision of publicly available electronic communications services or of public communications networks.
