Automate Backup in Linux Using RSYNC & Crontab | Backup Data On Remote Server Using RSYNC

#Welcome to Nehra Classes Youtube Channel#
#Automate Backup Using rsync & crontab in Linux#
============================================
rsync or remote synchronization is a software utility for Unix-Like systems that efficiently sync files and directories between two hosts or machines.
One of them being the source or the local-host from which the files will be synced, the other one being the remote-host, on which synchronization will take place.

There are basically two ways in which rsync can copy/sync data:
Copying/syncing to/from another host over any remote shell like ssh, rsh.
Copying/Syncing through rsync daemon using TCP.
============================================

Server: (192.168.1.111)

# yum repolist

# rpm -qa | grep rsync

# yum install rsync -y

# rpm -qi rsync

# su - vikasnehra

# mkdir backup

# cd backup

# touch test{1..10}.txt

# mkdir -p /tmp/backup

# rsync --help

# rsync -v /home/vikasnehra/backup/* /tmp/backup/

# exit

# mkdir -p /backupsource/

# cd /backupsource/ ; touch test{1..10}.txt

CLIENT: (192.168.1.108)

# yum repolist

# rpm -qa | grep rsync

# yum install rsync -y

# mkdir -p /backupdestination/

Go To SERVER:

Go To CLIENT:

# cd /backupdestination/

# ls -lha

# rm -rf *

# ls -lha /root/.ssh/

# mkdir -p /root/.ssh/

# chmod 700 /root/.ssh/

# touch /root/.ssh/authorized_keys

# chmod 600 /root/.ssh/authorized_keys

Go To SERVER:

Great video and great insight into in depth knowledge of data backup, can we do the real time sync for any file changed and can be synced for backup possibilities. Also is it possible to make the versioning of files, same like they are in the Google backup utility?
