  2. rsync - Wikipedia

    en.wikipedia.org/wiki/Rsync

    By default, rsync determines which files differ between the sending and receiving systems by checking the modification time and size of each file. If time or size is different between the systems, it transfers the file from the sending to the receiving system. As this only requires reading file directory information, it is quick, but it will ...

  3. Comparison of file synchronization software - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_file...

    Propagate renaming/moving of a file/directory. This saves bandwidth for remote systems but increases the analysis duration. Commonly done by calculating and storing hash function digests of files to detect if two files with different names, edit dates, etc., have identical contents. Programs which do not support it, will behave as if the ...

  4. Comparison of file transfer protocols - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_file...

    A packet-switched network transmits data that is divided into units called packets.A packet comprises a header (which describes the packet) and a payload (the data). The Internet is a packet-switched network, and most of the protocols in this list are designed for its protocol stack, the IP protocol suite.

  5. Data compression ratio - Wikipedia

    en.wikipedia.org/wiki/Data_compression_ratio

    Thus, a representation that compresses the storage size of a file from 10 MB to 2 MB yields a space saving of 1 - 2/10 = 0.8, often notated as a percentage, 80%. For signals of indefinite size, such as streaming audio and video, the compression ratio is defined in terms of uncompressed and compressed data rates instead of data sizes:

  6. File comparison - Wikipedia

    en.wikipedia.org/wiki/File_comparison

    File comparison is an important, and integral process of file synchronization and backup. In backup methodologies, the issue of data corruption is important. Rarely is there a warning before corruption occurs, this can make recovery difficult or impossible. Often, the problem is only apparent the next time someone tries to open a file.

  7. rdiff-backup - Wikipedia

    en.wikipedia.org/wiki/Rdiff-backup

    rdiff-backup recognizes changed files only by file size as well as modification time . To make sure all changed files have been backed-up, running rdiff-backup --compare-hash <source directory> <backup directory> (or rdiff-backup --compare-full <source directory> <backup directory> for a byte-wise comparison) will display all changed files.

  8. Rclone - Wikipedia

    en.wikipedia.org/wiki/Rclone

    Where checksums are not available, rclone can use object size and timestamp. [93] Rsync is single threaded. [94] Rclone is multi threaded with a user definable number of simultaneous transfers. [95] [96] Rclone can pipe data between two completely remote locations, sometimes without local download. During an rsync transfer, one side must be a ...
