Linux Rsync Parameters

After configuring the Rsync server, you need to issue an rsync command on the client to back up the files on the server to the client. Rsync is a very powerful tool, and its commands have many special options. The following describes the options one by one. The Command Format of www.2cto.com Rsync can be as follows: rsync [OPTION]... src dest rsync [OPTION]... SRC [USER @] HOST: DEST rsync [OPTION]... [USER @] HOST: src dest rsync [OPTION]... [USER @] HOST: src dest rsync [OPTION]... SRC [USER @] HOST: DEST rsync [OPTION]... rsync: // [USER @] HOST [: PORT]/SRC [DEST] corresponds to the preceding six command formats. rsync has six different working modes: 1) copy a local file. This mode is enabled when the SRC and DES paths do not contain a single colon ":" separator. For example, rsync-a/data/backup 2) uses a remote shell program (such as rsh and ssh) to copy the content of the local machine to the remote machine. This mode is enabled when the DST path address contains a single colon ":" separator. For example, rsync-avz *. c foo: src 3) uses a remote shell program (such as rsh and ssh) to copy the contents of the remote machine to the local machine. This mode is enabled when the SRC address path contains a single colon ":" separator. For example: rsync-avz foo: src/bar/data www.2cto.com 4) copy files from the remote rsync server to the local machine. This mode is enabled when the SRC path information contains the ":" separator. For example: rsync-av root@172.16.78.192: www/databack 5) copy files from a local machine to a remote rsync server. This mode is enabled when the DST path information contains the ":" separator. For example: rsync-av/databack root@172.16.78.192: www 6) List of remote machine files. This is similar to rsync transmission, but you only need to omit the local machine information in the command. For example, rsync-v rsync: // 172.16.78.192/wwwrsync:-v, -- verbose verq, -- quiet streamlined output mode-c, -- checksum: Enable the checksum function to force file transfer verification-a, -- archive mode, indicating that the file is transmitted recursively and all file attributes are kept, which is equal to-rlptgoD-r, -- recursive processes-R in recursive mode for subdirectories, -- relative uses relative path information-B, -- backup to create a backup, that is, when the target already has the same file name, rename the old file ~ Filename. You can use the -- suffix option to specify different backup file prefixes. -- Backup-dir: backs up files (for example ~ Filename) is stored in the directory. -Suffix = SUFFIX defines the backup file prefix-u. -- update only performs updates, that is, skipping all files that already exist in DST and whose file time is later than the backup time. (Do not overwrite the updated file)-l, -- links retains the soft link-L, -- copy-links: process soft links like regular files -- copy-unsafe-links: only copies links other than the SRC path directory tree -- safe-links ignores the directory tree pointing to the SRC path other links-H, -- hard-links keep hard links-p, -- perms keep File permissions-o, -- owner keep file owner information-g, -- group keep file group information-D, -- devices: Keep Device File Information-t, -- times: Keep file time information-S, -- sparse performs special processing on sparse files to save DST space-n, -- dry-run which files will be transmitted-W, -- whole-file to copy files without incremental detection-x, -- one-file-system: Do not span the file system boundary-B. -- block-size = SIZE indicates the block size used by the algorithm. The default value is 700 bytes-e, -- rsh = COMMAND specifies to use rsh and ssh for Data Synchronization -- rsync-path = PATH specifies the path of the rsync COMMAND on the remote server-C, -- cvs-exclude automatically ignores files in the same way as CVS to exclude files that do not want to be transmitted. -- existing only updates files that already exist in DST, instead of backing up those new files -- delete those files that are not in the dst src -- delete-excluded also delete the files that are excluded by this option at the receiving end -- after the delete-after transmission ends delete -- ignore-errors and delete it when I/o errors occur in a timely manner -- max-delete = NUM delete a maximum of NUM files -- partial keep those files that are not completely transmitted for any reason, to accelerate the subsequent re-transmission -- force the deletion of directories, even if it is not blank -- numeric-ids does not match the number user and group ID as the user name and group name -- timeout = time ip timeout TIME, in seconds-I, -- ignore-times does not skip files with the same time and length -- size-only. when determining whether to back up a file, only check the file size, regardless of the file time -- modify-window = NUM determines whether the file is time-stamped, the default value is 0-T -- temp-dir = DIR. Create a temporary file in DIR -- compare-dest = DIR and compare the files in DIR to determine whether to back up-P is equivalent to -- partial -- progress display. backup process-z, -- compress compresses the backup files during transmission -- exclude = PATTERN specifies to exclude the file mode that does not need to be transmitted -- include = PATTERN specifies the file mode to be transmitted without exclusion -- exclude- from = FILE exclude files in the specified mode -- include-from = FILE do not exclude files in the specified mode of FILE -- version print version information -- address bound to a specific address -- config = FILE specify other configuration files, do not use the default rsyncd. conf file -- port = PORT specify other rsync service ports -- blocking-io for remote shell use blocking IO-stats to give the transmission status of some files -- progress actual transmission process -- log -format = formAT specify the log file format -- password-FILE = FILE get the password from the file -- bwlimit = KBPS limit I/O bandwidth, KBytes per second-h, -- help displays help information. Generally, azv option rsync-vzrtopg -- delete -- progress/root @ 192.168.1.3: test is used.
