You must have established SSH between two hosts
The most wonderul synchronization tool that can be used locally or remote host. Knowing how to properly utilize rsync can streamline backups.
- preserves file permissions, modifications, and timestamps
- symbolic links in absolute and relative paths will be re-created
- data is only transferred as needed making it efficient
- transfers occur over SSH for security
Additional Examples direct link to this section
root@debian-nginx2:~# rsync /root/myveryimportantdirectory root@192.168.0.150:/root/
skipping directory myveryimportantdirectory
root@debian-nginx2:~# rsync -a /root/myveryimportantdirectory root@192.168.0.150:/root/
using ZIP direct link to this section
root@debian-nginx2:~# zip -r backup-$(date --iso-8601) /root/myveryimportantdirectory/
adding: root/myveryimportantdirectory/ (stored 0%)
adding: root/myveryimportantdirectory/myveryimportanttext.txt (stored 0%)
send backup to desired host:
root@debian-nginx2:~# rsync backup-$(date --iso-8601).zip root@192.168.0.150:/root/backups/

Web server example where the /var/www/html directory tree will be copied to the remote host:
$ rsync -av --progress \
--exclude '*.swp' \
--exclude '/old-css/' \
--exclude '/old-js/' \
/var/www/html/ example.com:/var/www/html
Where -a denotes archive mode and -v denotes verbose mode (all transfers are narrated).
