 What do you think? Yeah works like this So I'm not next because did echo Liveda and he's preparing a live demo, so let's hope for him everything works out Give him a warm welcome, please Hello, everybody. Thank you for coming to this talk. It's just a light demo about How to have a healthy and easy to use disaster recovery environment? with two problems projects relax and recover and just to recover Linux manager one is the client site and There is the server side there to virtual machines here a client on a server and Because some issues with the Wi-Fi today. I've just Already do the first step that is register a new network to the server in order to be able to handle the clients and manage them and after that at the The new a new client to the to the server, you know to and in the in the in the with the same common We are also installing it with a user with with privileges root privileges, okay the is that easy to That to run that common and When I when we're in the that common the the relax and recover and And all its dependencies are installed on the on the client side and now is ready to to run a backup The just a recovery backup in order to recover the the client. Let's do it Okay. No, we are running the the backup and We can see here that the relax and recover is running on the client side and if we can see from the server side here, we have the The locks from the server side and Also From the client side sent on in real time over the network Okay, this is right now here. Let me change This profile also, you know to see better what's happening This is the it's performing the backup on the client and these are the server side logs on top and the client side block On the RLM server. It's the log is sent In real time to the server in order to handle All the locks from one place. Okay In the meantime, I can Show you here the client only have This small configuration because all the configuration exclude file systems mom points directories, etc and client configuration it's it's saved and Managed on the server side and each time the client is Performing the backup the first one thing that does is download the last configuration from the server and Apply it and run the backup. Okay. This backup will be Say stored in the in the server you can manage and configure a set how many backups you want to store on the server and it keeps Removing the oldest backups always and keep by default enabling the last one to be able to recover it In just just after the backup is Is done Well It's done now. It's the backup is finished Let's see it here. Okay. The backup is already done and No, we'll break the client Okay, the system is break. I don't have any binary things like that let me Go here and power off because I cannot power off inside The client and now it's as easy to go here change the boot order Because it was this Put network on Disable this for the virtual box And as you can see now, we are booting from the network. The error server is already configured automatically after the client and here we can Start it's the DLM boot options boot menu. It's a group based and after that we are Downloading the kernel and in the RD match from the server that the backup did it and put on the server side and At the end of this loy loading this we will have the rescue system up and running and ready to recover the client again, okay and just in it's It's finishing out the boot Getting the IP from the DLM server also It's the the IP address It's offered on the HCP, but it's the IP address of the of the line if you have a static address configured okay, we log in here and Just need to do rear recover and now it's It's re-resort gating the partition layouts and Putting out all the things these two Correctly and now yeah, it's restoring the all the files on top of the file systems are just recreated well It's few minutes and in the meantime We run the the backup manually from the the shell, but we also can a schedule it With a plan plan some backups with some repetitions with the internet the scheduler on The DLM server if we have time, I think we will have time I will show you how to plan some backups and also how to export an import backup image in order to To do system migrations and new deployments based on on Linux backups with the alignment rear let me Stop this this machine now in order to set up again the correct boot order and give it another again Internet connection and now we can see that Okay, we are here in the clean again just recover it from crushed machine, okay Let's see now that we can do Plan a job with This common Okay, we're setting a job for today at 7 at 5 p.m. with Repeating it each week we can go from minutes to weeks months years and you can have multiple jobs for each client if you want And we can see now their list job That there is plan for the next date and after that execution will this Time and date will be put on the last date Execution and the next day will be Reschedulate, okay, automatically you can also set an end date for the backup In order if you want three months each day backup for example and and doing backups automatically The job will be removed and you you are sure that every day or every week during three in the next three months. For example, you have backups automatically schedule and Another interesting thing. It's the export and import of backups. Okay, we can do Backup we have only one backup well Okay, we can export that backup to TMP export Dr Okay, we export it. We are exporting it to a file Okay, this file could be sent to another there and serve another site another at the center anywhere With another client we can import another client. No, we will create a dummy client Here have the comments to be fast Because it's a lighting talk. I miss that We are know with this common. We are just registering the client to the server Okay, and the previous one we registered the client to the set in the server and also perform an automatic installation of the all Dependencies here is not needed because we have an empty a new client a new machine new vm mtvm or a new hardware and we just need to add the IP address that we have on my cadres and attach it to the correct network and after that we can do a import to this client from the file we just the backup we just export it and after that We will be able to recover this new empty machine dummy. We will I don't have this this machine, but as you can see here Now we have The new it's the same image. It's a new backup registered for this client And you can boot mtvm with its Mac address that we registered in the server and we will be able to deploy a new a new a new server a new client With your based a template or golden image if you want and you can keep deploying new systems in this way also migrating from different different data centers a Server you can take a backup export it send into a new DLM server another center import on a new client image in order to recover This that server on the new data center for example, okay? It's a tool for disaster recovery in it's this main focus, but it's very useful for new deployments and Also systems migrations and if you use it for that and the time when you are installing new new servers systems Or migrating it from new all the hardware the newer one you are testing your disaster recovery In in just a recovery the most important thing is testing Okay And if you use it in order to deploy new deployments and do hardware migrations You are testing it on at install time What at migration time and you have time to solve some issues with new hardware that you always have okay? and put the old core configurations on the on the server and You after that after the disinstallation all that all the tests are done, and if in case of a real issue Real disaster you you you are you will be sure that? Your system is is correct configured, and you will be able to recover it. This is How it works is pretty easy to have a healthy disaster recovery environment with relax and recover and the RLM I hope you enjoyed the talk, and if you have some questions or runs Well, I will answer it because I have 50 seconds Yeah, please Okay, yeah the answer the answer is if we can do it with The question is if we need to if we can do it also with Physical machines yes, you can do you use it for virtual machines physical machines and also in order to perform migrations from virtual to physical or physical to virtual and You don't need to have the same infrastructure. You can move virtual machines from VMware to KVM
