WEBVTT 00:09.080 --> 00:15.670 Have friends welcome back welcome to this final lesson of this course is to get in this lesson we're 00:15.670 --> 00:22.300 going to talk about the disaster recovery and management steps and disaster recovery or planning for 00:22.300 --> 00:23.880 disaster recovery. 00:23.880 --> 00:27.850 It's a very important step for a Linux administrator. 00:28.030 --> 00:35.260 So in this lesson I'm going to talk about the important points you should consider before planning a 00:35.260 --> 00:41.790 disaster recovery plan all of these points will help you plan a proper disaster recovery plan. 00:41.970 --> 00:44.940 OK for your company or organization. 00:45.220 --> 00:47.950 So let's see these points one by one. 00:48.040 --> 00:55.120 The first point is I think and right down it depends on what company you work or what company you are 00:55.120 --> 00:55.720 working on. 00:55.720 --> 00:57.200 So what type of company. 00:57.250 --> 01:04.330 How let's think about what Bibo possible disasters that could happen to you a system and write down 01:04.360 --> 01:07.070 all those possible disasters on paper. 01:07.160 --> 01:07.760 OK. 01:07.990 --> 01:16.870 So this will be our rough plan on paper which will help us to determine exactly what type of steps that 01:16.930 --> 01:17.940 we need to take. 01:17.990 --> 01:18.560 Okay. 01:18.790 --> 01:27.010 So the next step is you need to perform data backup and distortion data is very important for every 01:27.010 --> 01:28.300 organization. 01:28.500 --> 01:34.400 So you are working in a e-commerce company then customer data is really important for you. 01:34.500 --> 01:34.940 OK. 01:35.110 --> 01:42.270 If you are in Linux administrators in that company then in this case performing the data backup on a 01:42.270 --> 01:46.440 daily basis or hourly basis is really important. 01:46.550 --> 01:47.110 Okay. 01:47.260 --> 01:55.210 So setting up data back up on hourly or daily basis will be helpful for you and for some organization 01:55.210 --> 02:02.260 data is important but not that important so for such organizations you can celebrate about groups on 02:03.030 --> 02:05.920 a weekly basis or twice a week. 02:06.050 --> 02:06.460 OK. 02:06.520 --> 02:07.650 In that way. 02:07.860 --> 02:08.380 OK. 02:08.560 --> 02:12.350 And after that debacle why we need to perform restoration. 02:12.480 --> 02:12.910 Okay. 02:12.970 --> 02:21.120 Sometimes what happens on the back of face sort of files get caught up OK so distorted or backup is 02:21.130 --> 02:25.130 successful or not renew can form the restoration procedure. 02:25.340 --> 02:25.780 OK. 02:25.960 --> 02:29.850 So restoration is also an important part of the data backup. 02:29.860 --> 02:38.080 So you need to perform you not only to perform restoration every time you can perform it once or twice 02:38.170 --> 02:42.180 every day fought against your data backed up. 02:42.790 --> 02:49.990 The next step is you need to set the proper user file permissions and include in the data in this step 02:49.990 --> 02:57.730 you need to set up the proper permissions for user permission means so unique to you want them to have 02:57.730 --> 03:00.250 sort of access or not are you. 03:00.310 --> 03:05.160 You want them to have access to some important files or not. 03:05.170 --> 03:11.270 OK you can set the proper permissions for some important files like possible files OK. 03:11.310 --> 03:14.630 Against some normal or average users. 03:14.650 --> 03:14.940 OK. 03:14.950 --> 03:19.340 You need to think about it down send them those permissions. 03:19.470 --> 03:19.940 OK. 03:20.050 --> 03:28.150 So this is the first step and encrypting of data will be additional security against the the kind of 03:28.150 --> 03:33.290 disaster the next step is how a proper upgraded network diagram. 03:33.480 --> 03:33.730 OK. 03:33.730 --> 03:39.320 If you are working in a large organization and you view how multiple servers. 03:39.550 --> 03:45.070 OK so how many make good background will help you to figure out the problem. 03:45.070 --> 03:49.120 Suppose you are a large number of network. 03:49.270 --> 03:52.820 Any computer or system causing a problem. 03:52.900 --> 03:58.240 Then to figure out of that problem this diagram will help you. 03:58.250 --> 04:01.850 OK we'll help you to figure it out really quickly. 04:02.020 --> 04:02.290 OK. 04:02.350 --> 04:07.450 So make sure to how a proper network diagram of your network. 04:07.450 --> 04:13.960 The next step is you need to monitor software and hardware regularly monitoring software means to do 04:14.010 --> 04:22.120 it for updates regular updates software softwares like rootkit hundred or malware scanner will be ready 04:22.260 --> 04:29.590 to support you for a system to protect against new viruses all kinds of attacks and monitoring hardware 04:29.590 --> 04:33.420 regularly means you can monitor the performance of your hardware. 04:33.650 --> 04:34.080 OK. 04:34.120 --> 04:36.640 And you can move by monitoring that. 04:36.790 --> 04:42.370 You can protect against the sudden loss of a hard drive on RAM. 04:42.610 --> 04:48.190 So doing it regularly you will at organs and that kind of disaster. 04:48.460 --> 04:50.920 The next step against power outage problem. 04:51.100 --> 04:52.080 OK. 04:52.150 --> 05:00.880 Having continuous power supply or power is also an important step in disaster recovery sudden loss of 05:01.030 --> 05:10.460 power will be a big disaster for a company or organization that could cause a great loss for a company. 05:10.640 --> 05:19.130 So for such kind of disasters you can how and you pierce or you can how additional utility line or the 05:19.130 --> 05:25.570 third one is you need to have an emergency generators for your company or organizations. 05:25.880 --> 05:26.390 OK. 05:26.540 --> 05:29.760 And the last step is this recovery plan. 05:29.840 --> 05:37.360 No matter how good your plan is until you get that plan you're never going to know how it works. 05:37.460 --> 05:37.780 OK. 05:37.850 --> 05:43.670 So the sting of your recovery plan is very very important step in in disaster recovery and management 05:43.670 --> 05:44.750 plan. 05:45.020 --> 05:51.890 So when you go through these steps you will have a perfect disaster recovery and management plan for 05:51.890 --> 05:56.800 your company or organization where you're going to work as in Linux and ministered. 05:57.100 --> 05:57.680 OK. 05:57.680 --> 06:02.520 So thank you so much for enrolling in the schools and in the next lesson. 06:02.690 --> 06:09.240 I'm going to talk about how to find a job or how you can work on line as a Linux administrator. 06:09.300 --> 06:17.810 OK you can make actually thousands of dollars a year working online are you can find a job where you 06:17.810 --> 06:20.670 can make thousands of dollars a year. 06:20.900 --> 06:22.910 OK on the basis of discourse.
