rsync - 10 examples in 11 days (Day 01)

Sync Files and Directories Locally

Let's say we have a directory called Users. Inside of this folder we have various .json files with user settings. This is how our tree will look like:

  • Users
    • user01.json
    • user02.json
    • user03.json

To be sure we sync all our files and they were copied correctly, we can check the file size of each one. Inside the users folder and using the stat command with the -c option and the %s %n arguments to show only the size and the name of each file:

iamgroot@laptop:~$ stat -c "%s %n" ~/Users/*
92 user01.json
57 user02.json
69 user03.json

Enter fullscreen mode Exit fullscreen mode

As you can see, each file have different size and they are displayed in bytes ie: 92bytes for user01.json file.

Now that we know what we have, let's sync it:

iamgroot@laptop:~$ rsync -vhr /home/iamgroot/Users /home/iamgroot/SyncFiles

sending incremental file list
Users/
Users/user01.json
Users/user02.json
Users/user03.json

sent 478 bytes  received 77 bytes  1.11K bytes/sec
total size is 218  speedup is 0.39
Enter fullscreen mode Exit fullscreen mode

Let's verify if the folder and its files were copied to the destination folder

iamgroot@laptop:~$ ls -h ~/SyncFiles && stat -c "%s %n" ~/Users/*

92 user01.json
57 user02.json
69 user03.json

Enter fullscreen mode Exit fullscreen mode

We can see we have the Users folder copied, all files are inside of it and the file size are exactly the same as the source


Ok, that'll be for today's example, thanks for reading!!!

Looking forward to the rest of the series. On my todo list is set up sync from my NAS to an external hard drive for safe keeping
