matching sources, so that the sender does not need to send parts that match these data sources ). To achieve this remote data matching, a block checksum code (block checksum) will be created for the basis file and sent to the sender immediately after the file index number (file id. If the "-- whole-file" option is specified, an empty block check code will be sent for the new file (that is, the file that the sender has but the file that the consumer does not. (Note: generator sends the block ver

In the source code, a perl script program named rsyncstats is released to collect statistics on log files in this format. Timeout overwrites the specified IP timeout value. This option ensures that the rsync server will not always wait for a crashed customer. Timeout is measured in seconds. 0 indicates that no timeout is defined. This is also the default value. An i

In addition, hosts allow restricts the synchronized ip addresses. Multiple ip addresses are separated by spaces. Auth users and secrets files are
