WebMar 27, 2001 · A checksum is a value which is computed which allows you to check the validity of something. Typically, checksums are used in data transmission contexts to detect if the data has been transmitted successfully. Checksums take on various forms, depending upon the nature of the transmission and the needed reliability. WebFor --ignore-times: In case rsync is not smart (or does not trust the delta encoding) then the checking (checksumming and encoding) will be done twice. It could also be the case that delta encoding is much slower than the 128-bit MD4 checksumming. Both --checksum and --ignore-times will be "quite slow" but --ignore-times is likely even slower ... brink night cap
