As some people already asked you can find the slides of my talk at SambaXP here.This instructable will show you how to keep two folders and all folders within them in sync so one is a direct copy of the other.

No experience with programming is necessary to complete this tutorial. Please note this only works with Windows although the process is similar on Mac and Linux. I have an old windows computer that I have setup acting as a server for various functions, one of which is a cheap network attached storage which acts as both a media server and backup to all my family's computer data. As my family all like to work locally on their PCs, we needed an easy way to backup our data regularly.

I also needed a way to double down on the backup by implementing a RAID like approach on two hard drives on the server PC. I also did not want to pay for any software yes I know stingy me. As a consequence of this, all free software tends to come with pop ups or even slowed down the PC with long sync times and big CPU usage, which was just annoying.

Therefore with a small bit of effort, I wrote a python script which would sync the folders we all needed. I could then customise and distribute this to the family as an executable which I could set windows to run on a regular basis in the background. The computer user had to be none the wiser. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. To create the distributable program you need to install python on your computer.

Unfortunately, the module pyinstaller which we will use does not work yet with python 3. I used 3. Once installed open up a command prompt and install the python modules we need, to do this type the following and follow through with any prompts as required:. The script is nice and simple, only two lines, copy and paste the following into either IDLE installed with Python or notepad and save as "DirectorySync. Make sure to change the two folders above with the two folders you wish to sync.

The double backslash is required in the path name as the backslash is an escape character in Python. The second performs the sync. The first folder is the source folder and the second is the target, the 'sync' is the telling the sync function what syncing mode to implement.

There are other options which can be implemented depending on your needs.Details are below. I have multiple server-based computers, but they are in different places. I need to use files on other computers frequently. Is it possible to synchronize files between Windows Servers?

Any suggestion and comment are welcome. For Server users, you could use the built-in role services DFS replication.

Also, you need to keep up with the changed, newly added or deleted files if someone modifies it.

How to sync sync files between Windows Servers? Both can help you to tansfer files from server to server.

All your files are NTFS file system. Whenever you meet problems concerned to your computer, you may think about Windows built-in tool in the first time. Syncing folders in Windows Server is not an exception. DFS replication is not installed by default, thus you need to install DFS replication first and then perform file replication. Confirm you want to install the roles, role services, or features, then click Install. Wait for the installation process, then click Close after you see the results with Installation succeeded marked.

Set a name and domain for your replication group, then click Next. Click Add and look up the servers in Active Directory, then select the servers you want to share files or folders and click Next.

You will be noted to use Hub and spoke. However, there is no need to use it in most cases, so you can use it or not according to your situation.

Choose to use full bandwidth if you want to keep the files in sync all the time. To avoid file conflict in the first synchronization, you need to choose a Primary member.

After the first synchronization, all the files will be synchronized nearly instantaneously, because the Full mesh topology treats all servers as equals. Click Add and you will enter a new window, then select the folders you want to replicate and click Next.With the help of rsync command you can copy and synchronize your data remotely and locally across directories, across disks and networks, perform data backups and mirroring between two Linux machines.

This article explains 10 basic and advanced usage of the rsync command to transfer your files remotely and locally in Linux based machines. This following command will sync a single file on a local machine from one location to another location. Here in this example, a file name backup. In above example, you can see that if the destination is not already exists rsync will create a directory automatically for destination. The following command will transfer or sync all the files of from one directory to a different directory in the same machine.

This command will sync a directory from a local machine to a remote machine. This command will help you sync a remote directory to a local directory. With rsync, we can use SSH Secure Shell for data transfer, using SSH protocol while transferring our data you can be ensured that your data is being transferred in a secured connection with encryption so that nobody can read your data while it is being transferred over the wire on the internet.

It displays the files and the time remaining to complete the transfer. Target has the new file called test. You can specify the Max file size to be transferred or sync. Here in this example, Max file size is kso this command will transfer only those files which are equal or smaller than k. So, will you wait for transfer to complete and then delete those local backup file manually?

Of Course NO. Rsync could really mess up the things in your destination folder and then doing an undo can be a tedious job.

By default this is rsync.

What happens if you accidentally delete a file on your hard drive? It also gets deleted on your external "backup" drive. Backups usually comprise more than one generation of files so you can retrieve accidentally deleted files from it. While that may seem paradoxical, it is useful when dealing with files larger than git can currently easily handle, whether due to limitations in memory, time, or disk space.

Isn't it too heavy it check every files if something is changed? DRBD can be a bit complicated to configure, if you need help configuring it I wrote a nice article: geek-kb.

Also a software raid with internal and external hard drive members is probably going to be very slow, unreliable and designated to break pretty often.

How To Keep OneDrive In Sync With A Folder On Linux Using OneDrive Free Client Fork

I have two directories present on two different server. Now i want to check if all files are in sync in both the directories. If files are not in sync then i want to display only name of those files.

I am able to do it when directories are on same server. You can use rsync with the -n flag to find out if the files are in sync, without actually doing a sync. This is pretty fast but probably not as accurate as rsync since it uses file size instead of hash of content. Also, the rsync from kielni's answer will not show anything if server2 has more files then server1.

Instead try this:. In scenario of no connectivity between two servers, use "tree" command to get directory structure in files and then diff two files. I always use rsync -avcn for such tasks - I am a CLI fan.

The idea is to do a "dry run" -nwhich shows what would have been done without actually copying any files or making any changes. Using the -c switch is really important as it uses the checksum rather than the modification date or file size to determine if the files are different. Finally, -v increases the level of verbosity, which is useful in case different files are found. Note the trailing slashes - they are essential.
