Definition: BKS refers to a specific type of text file in Unix/Linux systems, specifically used for backup data and logging purposes. "B" stands for binary (as opposed to ASCII). Key bytes are saved as binary (16 bit) files; this allows more efficient storage by avoiding redundancy and speeding up operation times due to the binary format's less overhead. The second part of the word, "2", stands for two. This refers to the number of data blocks in each file, which is important in terms of scalability. In Unix/Linux systems, a backup directory can contain many files (BKS), which are stored at the same location as the primary backup file. Definition: 1. A binary (binary) format of data that supports lossless compression, meaning it's easier to read and write than ASCII text. 2. A term for a single piece of information that is saved in two separate files, usually used in Unix/Linux systems where backups are kept for multiple months or years. In practical terms, when you run a script from the command line, the output will be stored as BKS data (binary) files in a backup directory.
