Have friends welcome back welcome to this final lesson of this course is to get in this lesson we're
going to talk about the disaster recovery and management steps and disaster recovery or planning for
disaster recovery.
It's a very important step for a Linux administrator.
So in this lesson I'm going to talk about the important points you should consider before planning a
disaster recovery plan all of these points will help you plan a proper disaster recovery plan.
OK for your company or organization.
So let's see these points one by one.
The first point is I think and right down it depends on what company you work or what company you are
working on.
So what type of company.
How let's think about what Bibo possible disasters that could happen to you a system and write down
all those possible disasters on paper.
OK.
So this will be our rough plan on paper which will help us to determine exactly what type of steps that
we need to take.
Okay.
So the next step is you need to perform data backup and distortion data is very important for every
organization.
So you are working in a e-commerce company then customer data is really important for you.
OK.
If you are in Linux administrators in that company then in this case performing the data backup on a
daily basis or hourly basis is really important.
Okay.
So setting up data back up on hourly or daily basis will be helpful for you and for some organization
data is important but not that important so for such organizations you can celebrate about groups on
a weekly basis or twice a week.
OK.
In that way.
OK.
And after that debacle why we need to perform restoration.
Okay.
Sometimes what happens on the back of face sort of files get caught up OK so distorted or backup is
successful or not renew can form the restoration procedure.
OK.
So restoration is also an important part of the data backup.
So you need to perform you not only to perform restoration every time you can perform it once or twice
every day fought against your data backed up.
The next step is you need to set the proper user file permissions and include in the data in this step
you need to set up the proper permissions for user permission means so unique to you want them to have
sort of access or not are you.
You want them to have access to some important files or not.
OK you can set the proper permissions for some important files like possible files OK.
Against some normal or average users.
OK.
You need to think about it down send them those permissions.
OK.
So this is the first step and encrypting of data will be additional security against the the kind of
disaster the next step is how a proper upgraded network diagram.
OK.
If you are working in a large organization and you view how multiple servers.
OK so how many make good background will help you to figure out the problem.
Suppose you are a large number of network.
Any computer or system causing a problem.
Then to figure out of that problem this diagram will help you.
OK we'll help you to figure it out really quickly.
OK.
So make sure to how a proper network diagram of your network.
The next step is you need to monitor software and hardware regularly monitoring software means to do
it for updates regular updates software softwares like rootkit hundred or malware scanner will be ready
to support you for a system to protect against new viruses all kinds of attacks and monitoring hardware
regularly means you can monitor the performance of your hardware.
OK.
And you can move by monitoring that.
You can protect against the sudden loss of a hard drive on RAM.
So doing it regularly you will at organs and that kind of disaster.
The next step against power outage problem.
OK.
Having continuous power supply or power is also an important step in disaster recovery sudden loss of
power will be a big disaster for a company or organization that could cause a great loss for a company.
So for such kind of disasters you can how and you pierce or you can how additional utility line or the
third one is you need to have an emergency generators for your company or organizations.
OK.
And the last step is this recovery plan.
No matter how good your plan is until you get that plan you're never going to know how it works.
OK.
So the sting of your recovery plan is very very important step in in disaster recovery and management
plan.
So when you go through these steps you will have a perfect disaster recovery and management plan for
your company or organization where you're going to work as in Linux and ministered.
OK.
So thank you so much for enrolling in the schools and in the next lesson.
I'm going to talk about how to find a job or how you can work on line as a Linux administrator.
OK you can make actually thousands of dollars a year working online are you can find a job where you
can make thousands of dollars a year.
OK on the basis of discourse.
