Checksum is a simple method of detecting errors in data
A checksum is a simple type of redundancy check that is used to detect errors in data.. Errors frequently occur in data when it is written to a disk, transmitted across a network or otherwise manipulated. The errors are typically very small, for example, a single incorrect bit, but even such small errors can greatly affect the quality of data, and even make it useless.
Memory Technology Device (MTD) Subsystem for Linux.
Write-back support. UBIFS supports write-back, which means that file changes do not go to the flash media straight away, but they are cached and go to the flash later, when it is absolutely necessary.

ext3 - Wikipedia
ext3, or third extended filesystem, is a journaled file system that is commonly used by the Linux kernel.It used to be the default file system for many popular Linux distributions. Stephen Tweedie first revealed that he was working on extending ext2 in Journaling the Linux ext2fs Filesystem in a 1998 paper, and later in a February 1999 kernel mailing list posting.
Prüfsumme – Wikipedia
In der Informationstechnik ist eine Prüfsumme (englisch checksum) ein Wert, mit dem die Integrität von Daten überprüft werden kann. Prüfsummen werden typischerweise bei der Datenübertragung oder der Datensicherung verwendet. Grundsätzlich ist eine Prüfsumme ein Wert, der aus den Ausgangsdaten berechnet wurde und in der Lage ist, mindestens einen Bitfehler in den Daten zu erkennen.
rsync - Wikipedia
rsync is a utility for efficiently transferring and synchronizing files across computer systems, by checking the timestamp and size of files. It is commonly found on Unix-like systems and functions as both a file synchronization and file transfer program. The rsync algorithm is a type of delta encoding, and is used for minimizing network usage. Zlib may be used for additional data compression ...
