Let's Talk About Tech!

Background Nextcloud is a well known file share platform, open source, freely available with nice syncing features. It is the OwnCloud "successor". The platform is providing a web based portal to manage files and shares but as well syncing clients are available on most OSs. The use case I'm trying to achieve here is the file-level restoration. Most of the time, the backup is doing a full VM backup with all files. But what if a user is requesting a restoration of a single file or directory ?

Background If you are already using an object store, you probably have a use case where you want to access the content of the bucket directly from the Linux filesystem. In my case, I'm using Cloudian, and I would like to directly read/write content from/to my Linux machine. Cloudian is object store and Linux is using traditional block store. But, wait ! it is possible to mix those environments !

Background One way to save on expanding a Rubrik Cluster is to offload it. You can do that with an on-prem object store, or in the cloud. But if on-prem is still your way to go, you can consider object store solution. You already know about OpenIO but there are other players : Cloudian is one of them. Their architecture is web scale, same way as Rubrik, Nutanix and all the modern companies these days. The good think with Cloudian is the cloud tiering. If some archives are exceeding a certain lifetime, you can decide to offload your Cloudian appliance and start moving them in the cloud of your choice. Very clever !

Background A long time ago, I was in a plane for more than 10 hours and I had to utilize that time efficiently. I decided to open my laptop and start coding. But, while being off-net for a long period of time, I had no distraction and started to think. I was creating an application that was generating a lot of logs and I thought important to keep them in an efficient way. This is why log rotation came to mind.

Background     I did a mistake - we all do - I have changed the specs on the wrong VMs and of course I did not recall the original settings. I thought I could get them from my backup since all these details are retained when we need to export the VM. Ok, but how ?

Background It's been a while since I'm involved with Rubrik. I was fortunate enough to be part of the CDM 4.0 beta test, helping Rubrik Engineers to polish Nutanix AHV support. This is a great opportunity to be an early adopter, you have the ability to help driving the product into the right direction. One of the achievements I had in mind was to pass the certification. Probably not as easy as it had thought ....

Background After publishing my post about Rubrik Central  months ago, I have received comments saying that it is too difficult to deploy and has too many pre-requisites. I thought about automating the deployment process in many ways and found that containers could be a nice option. But I didn't know anything about Docker. So, I did some research and I think I came across with something definitely usable !

Background I have a home automation system at home (you know that from the Yamaha  article ) and I would like to know the travel time while having breakfast. Always good to plan ahead for any hiccup on the road. Easy to get this info on Google map, but you need a browser and a few clicks, I would like something automated !

Background Yes, Yamaha, I know this is not an usual topic on this blog, but don't worry, we will still code a little ;) Modern amplifiers and home cinema's are now connected. Some with wifi, some with ethernet. It would be nice to have the ability to control them. Mine is a RX-V673, too old to have WiFi but I have an Ethernet port. There is a smartphone app as well. If there is connectivity and an app, for sure we can hack it !

Background Now that we have seen how to get and apply categories and values to VMs, it is about time to learn how to create categories and values. Indeed, to be able to apply categories to VMs they first need to be created and ready to be used. Nutanix allows us to create whatever categories we have in mind.
