CwRsync enables synchronous backup between windows Servers

Today I tested for a long time about using cwrsync to synchronize data between two servers, and it took some time to make it at noon. Next I will introduce the specific operation method of cwRsync to implement synchronous backup between windows servers.

Cwrsync is divided into two parts: client and server. Let's talk about cwrsync 4.0.. In contrast, cwrsync_4.0.5_installer.zipand cwrsyncserver_4.0.5_installer.zip

1. install and configure the cwRsync Server
1) install cwRsyncServer on the Domain Server (cwRsyncServer_4.0.5)
Note: The default user name and password of cwRsync are as follows:
 
You must change the user name and password of the current system administrator to start the cwRsync service:
 
3) Prepare the File folder (File Server Directory) and Data folder (Database directory) on the Domain Server as the folder for Synchronizing files.
4) Open the serverRsyncd. configFile. The default configuration is as follows:
 
5) modifyRsyncd. configThe file content is required as follows:
Note: In the preceding content, set the listening port to the default value of 873.
6) on the control panel, choose management tools> services, find the service and start it, for example:

2. install and configure the cwRsync Client
1) install the client cwRsync_4.0.5 on the backup server and create a folder named sync, at the same time, create two folders named "File" and "Data" below to synchronize the folders on the Domain Server.
 

2. Create a password.txt file on the C drive and write the logon password of the Domain Server administrator.
3) create a batch file named work_rsync.bat in the following content:

-- These two processes Incremental backup.

Rsync-avz -- progress administrator@192.168.1.87: t_File/cygdrive/c/sync/File <c: password.txt
Rsync-avz -- progress administrator@192.168.1.87: t_Data/cygdrive/c/sync/Data <c: password.txt
 

Put it in the bin directory under the installation directory of the cwRsync client (my installation directory is as follows: C: Program FilescwRsyncbin), and double-click to start it. In this way, the file will be synchronized:

Then, we can see the synchronized files in the corresponding directory of C: sync, as shown below.

Note: cwRsync synchronizes incremental and modified files. When the corresponding files on the server are modified, the client synchronizes the modified files or new files.

Finally, we can use windows scheduled tasks to regularly synchronize instances.

Rsync Command Parameters

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) use 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) use 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
4) copy files from the remote rsync server to the local machine. This mode is enabled when the SRC path information contains the ":" separator. Such as: rsync-av root@172.16.78.192: www/databack
5) copy files from the local machine to the remote rsync server. This mode is enabled when the DST path information contains the ":" separator. Such as: 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/www
The rsync parameters are described as follows:
-V, -- verbose detailed mode output
-Q, -- quiet simplified output mode
-C, -- checksum: enable the verification switch to force file transfer verification
-A, -- archive mode, indicating that the file is transmitted recursively and all file attributes are kept, equal to-rlptgoD.
-R, -- recursive processes subdirectories in recursive Mode
-R, -- relative uses relative path information
-B, -- backup creates a backup, that is, if the object 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 time to be backed up. (Do not overwrite the updated file)
-L, -- links retains soft links
-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 links other than the SRC path directory tree
-H, -- hard-links
-P, -- perms to keep File Permissions
-O, -- owner keeps file owner information
-G, -- group: Keep file group information
-D, -- devices: Keep Device File Information
-T, -- times preserve the 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: Copy files without incremental Detection
-X, -- one-file-system do not span the boundaries of the file system
-B, -- block-size = SIZE indicates the block size used by the algorithm. The default value is 700 bytes.
-E, -- rsh = COMMAND specifies that rsh and ssh are used 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 the files that already exist in DST, instead of backing up the new files.
-- Delete: delete the files that are not in the SRC file in DST.
-- Delete-excluded: delete Files specified by this option at the receiving end.
-- Delete-after: delete after transmission
-- Ignore-errors is deleted when an IO error occurs in a timely manner.
-- Max-delete = NUM: a maximum of NUM files can be deleted.
-- Partial retains the files that are not completely transferred for any reason, so as to speed up subsequent re-transmission.
-- Force directory deletion, even if not empty
-- Numeric-ids does not match the number user and group ID with the user name and group name.
-- Timeout = time ip timeout, in seconds
-I, -- ignore-times do 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 timestamp window of the file is used at the same time. The default value is 0.
-T -- temp-dir = DIR create a temporary file in DIR
-- Compare-dest = DIR: compare the files in DIR to determine whether to back up data.
-P is equivalent to -- partial
-- Progress displays the backup process
-Z, -- compress compresses backup files during transmission
-- Exclude = PATTERN specifies to exclude file modes that do 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 in the FILE.
-- Include-from = FILE: files with the specified FILE pattern matching are not excluded.
-- Version: prints version information.
-- Address: bind to a specific address
-- Config = FILE: specify other configuration files. The default rsyncd. conf FILE is not used.
-- Port = PORT specify other rsync service ports
-- Blocking-io: block IO for remote shell
-Stats indicates the transmission status of some files.
-- SS actual transmission process during transmission
-- Log-format = formAT specifies the log file format
-- Password-file = FILE get password from FILE
-- Bwlimit = KBPS limits I/O bandwidth, KBytes per second
-H, -- help: displays help information

Azv is generally used.
