  2. Data erasure - Wikipedia

    en.wikipedia.org/wiki/Data_erasure

    Many government and industry standards exist for software-based overwriting that removes the data. A key factor in meeting these standards is the number of times the data is overwritten. Also, some standards require a method to verify that all the data have been removed from the entire hard drive and to view the overwrite pattern.

  3. Clobbering - Wikipedia

    en.wikipedia.org/wiki/Clobbering

    In software engineering and computer science, clobbering a file, processor register or a region of computer memory is the process of overwriting its contents completely, whether intentionally or unintentionally, or to indicate that such an action will likely occur. [1] The Jargon File defines clobbering as

  4. Data remanence - Wikipedia

    en.wikipedia.org/wiki/Data_remanence

    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 ...

  5. Digital obsolescence - Wikipedia

    en.wikipedia.org/wiki/Digital_obsolescence

    Organizations possessing digital archives should perform assessments of their records in order to identify file corruption and reduce the risks associated with file format obsolescence. Such assessments can be accomplished through internal file format action plans, which list digital file types in an archive's holdings and assess the actions ...

  6. File system fragmentation - Wikipedia

    en.wikipedia.org/wiki/File_system_fragmentation

    File segmentation, also called related-file fragmentation, or application-level (file) fragmentation, refers to the lack of locality of reference (within the storing medium) between related files. Unlike the previous two types of fragmentation, file scattering is a much more vague concept, as it heavily depends on the access pattern of specific ...

  7. Bak file - Wikipedia

    en.wikipedia.org/wiki/Bak_file

    In computing, ".bak" is a filename extension commonly used to signify a backup copy of a file. When a program is about to overwrite an existing file (for example, when the user saves the document they are working on), the program may first make a copy of the existing file, with .bak appended to the filename.

  8. Data deduplication - Wikipedia

    en.wikipedia.org/wiki/Data_deduplication

    Source deduplication ensures that data on the data source is deduplicated. This generally takes place directly within a file system. The file system will periodically scan new files creating hashes and compare them to hashes of existing files. When files with same hashes are found then the file copy is removed and the new file points to the old ...

  9. File verification - Wikipedia

    en.wikipedia.org/wiki/File_verification

    File verification is the process of using an algorithm for verifying the integrity of a computer file, usually by checksum.This can be done by comparing two files bit-by-bit, but requires two copies of the same file, and may miss systematic corruptions which might occur to both files.
