If you want to back up a directory on a computer and only copy changed files to the backup computer instead of everything with each backup, you can use the rsync tool to do this. You will need an account on the remote computer that you are backing up from. Here is the command:
rsync -vare ssh jono@192.168.0.2:/home/jono/importantfiles/* /home/jono/backup/ Here we are backing up all of the files in /home/jono/importantfiles/ on 192.168.0.2 to /home/jono/backup on the current machine.

Class Notes
Backup Using TAR
Backup = sudo tar –cvpzf backup.taz.gz –exclude/=directory (recursive) PATH
–c = create new file (overwrites old file)
–v = verbose
–p = preserve permissions
–z = compress
–f = filename (very important)
–exclude=DIRCECTORY is Recursive
Naming Files with time = filename-$(date +%F-%T)
Recover Files from a TAR File
Recover = sudo tar –xvpzf FILE –C /DIRECTORY
Capital -C = change to directory
-x = extract
Cron Jobs
To Edit the Crontab File = sudo cron –e (first time it will ask you your default editor)
Format = minute (0-59), hour (0-23, 0 = midnight), day (1-31), month (1-12), weekday (0-6, 0 = Sunday), command
* Wildcard for Every Minute/Day/Hour/Month?Day of Week
Example to Backup Entire Server for 1am Every Morning = 0 1 * * * sudo tar -cvpzf /backup.tar.gz –exclude=/mnt /

I was running into some problem with CSF (Config Server Security Firewall)
In the Edit Config Server Firewall (Loggin Settings) I noticed that LFD was not automatically blocking attacks on the server.
Log lfd messages to SYSLOG in addition to /var/log/lfd.log. You must have the
perl module Sys::Syslog installed to use this feature
I had to install the Sys::Syslog perl module to make it work.
[root]# yum install perl-Sys-Syslog
Restart CSF and check the message log to see if there is any error like:
localhost systemd: Unit lfd.service entered failed state.
localhost systemd: lfd.service failed.
All working good now 😉
Usermin is a web-based interface for webmail, password changing, mail filters, fetchmail and much more. It is designed for use by regular non-root users on a Unix system, and limits them to tasks that they would be able to perform if logged in via SSH or at the console. See the standard modules page for a list of all the functions built into Usermin.
Who can use Usermin?
Most users of Usermin are sysadmins looking for a simple webmail interface to offer their customers. Unlike most other webmail solutions, it can be used to change passwords, read email with no additional servers installed (like IMAP or POP3), and setup users’ Procmail configurations for forwarding, spam filtering and autoreponders.
Usermin also provides web interfaces for viewing and managing data in MySQL and PostgreSQL databases, editing Apache .htaccess configuration files, and running commands on the server. The administrator has full control over which of these modules are available to users.
Usermin and Webmin integration
By far the easiest way to configure Usermin is via the Usermin Configuration module in Webmin. All functionality can be managed via a browser, and because both products come from the same developer the management user interface is always up to date.
