Then fill up the information for source and destination servers.A new pop up window will show up, Give your session a name.Create a new session by going sessions > add.One of the great benefit of using grsync is that it can be used to syncup folders between two servers. It has pretty simple GUI interface which is self explanatory. Once you have it installed, You can invoke the GUI by just typing grsync.

It works on all the major platforms, such as Centos, Ubuntu, Windows and Mac. Now I want to talk about another great Utility grsync, which is GUI utility for rsync. There are many other commands which rsync provides. Lets copy it from server2 to current /tmp/ directory rsync -ztva :/home/downloads/home/scripts /tmp/ Lets say we want to copy the scripts directory which is under the same path but on server2. Similarly we can copy one remote server too, only difference is that for source and destination you need to follow the ssh syntax. Lets check our scripts directory now in /tmp/ pwd ls -lrt /tmp/scripts Now we see the scripts directory copied too, the difference is the trailing trash, If you dont specify the trailing slash, it copies the directory too. Sent 1, 076 bytes received 77 bytes 2, 306.00 bytes/sec Lets see if we can copy the whole directory now with files rsync -ztva /home/downloads/home/scripts. rwxr-xr-x 1 root root 47 [ 0m[ 01 32mget_free_memory.sh[0m
ls -lrt get_free_memory.sh get_ipaddr.sh prepare.sh Seems like we didnt get the scripts directory, Lets see if we got the files. Ls: cannot access scripts: No such file or directory Seems like it has worked, let see if we got all the files and also the scripts directory pwd Sent 1, 059 bytes received 76 bytes 2, 270.00 bytes/sec We need to add the switch -a (archive) rsync -ztva /home/downloads/home/scripts/.
Sent 16 bytes received 12 bytes 56.00 bytes/secĪs we see above the same didnt work. Lets try to copy the whole directory scripts with all the files in it rsync -ztv /home/downloads/home/scripts. Get_free_memory.sh get_ipaddr.sh prepare.sh Following scripts directory has few files in it. Sent 44 bytes received 12 bytes 112.00 bytes/sec You can also use verbose mode to print information rsync -ztv /home/downloads/SampleData.xlsx. If the file is too big, use the -z compress switch, Rsync will compress the files before transfer rsync -zt /home/downloads/SampleData.xlsx. Now we got the file and also preserved the timestamp rw-r-r- 1 root root 65801 SampleData.xlsx To keep the original timestamp rsync -t /home/downloads/SampleData.xlsx. Yes we got the file in the directory /tmp/ directory but the time stamp has changed. Lets copy the above file /home/downloads/SampleData.xlsx to our current directory /tmp rsync /home/downloads/SampleData.xlsx. rw-rw-r- 1 root root 65801 Oct 31 2018 /home/downloads/SampleData.xlsx Lets start with a simple case where we want to copy a single file from source to destination. For a more detailed practical and mathematical explanation refer to how rsync works and the rsync algorithm, respectively.How to use Rsync and Grsync to securely copy files Using this information a large file can be constructed using rsync without having to transfer the entire file. For each file to be constructed, a weak and strong checksum is found for all blocks such that each block is of length S bytes, non-overlapping, and has an offset which is divisible by S. Whether transferring files locally or remotely, rsync first creates a file-list containing information (by default, it is the file size and last modification timestamp) which will then be used to determine if a file needs to be constructed. Network file transfers use the SSH protocol by default and host can be a real hostname or a predefined profile/alias from. Remote locations can be specified with a host-colon syntax: You may want to use the -r/ -recursive option to recurse into directories.įiles can be copied locally as with cp, but the motivating purpose of rsync is to copy files remotely, i.e. The -P option is the same as -partial -progress, which keeps partially transferred files and shows a progress bar. Rsync can be used as an advanced alternative for the cp or mv command, especially for copying larger files:
Note: Using rsync instead of cp/mv is efficient across different filesystems, but not for copying or moving files on the same filesystem.
