Automation of backup jobs

Today i want to start automating my tasks. This time i want to automate a backup task written in Python. In general the script collects mySQL database exports in zip-format and copies them into a folder which is then protected with a raid and a backup. I’m using a python script on the Windows Tasks Scheduler for this job.

See my wiki for a how to.

My old Nas

This is my old NAS based on an Intel Core i3-6100 from 2016. The system is using 5 Seagate NAS HDDs (ST4000VN000) in a storage space configuration using raid 5 mode. It was reliable, quiet and it ran almost 5 years without any issue. However it was too slow and i needed more space. It will serve as a playground for my future Youtube videos and maybe later as a backup machine.

New HBA has arrived

Finally i received my new Microsemi HBA 1100-16i SAS Controller. Now i can begin with setting up my hyperconverged server. This host bus adapter offers 4×4 internal Sata/SAS channels. Together with the ports from the mainboards this should be more than enough for any upgrades in the next few years.

Home-Server

I recently moved my files from a NAS to a Windows Server 2019 installation. For this I’m using Storage Spaces with tiered storage.

See my wiki for the HowTo: Create tiered storage spaces or my Youtube video.

Machine learning 1

In the last few years i heard a lot about machine learning, deep learning and machine learning. Since i was already planning to do a little bit more of python programming i want to start using it with Keras / TensorFlow to replay some of the beginner examples. I will run the examples on VMs on my new Server.

Why machine learning ?

Its simple: Its a future technology and currently a lot of companies are beginning to use it.

Why starting with TensorFlow ?

I read an article about a free “self-study guide for aspiring machine learning practitioners“. After doing the crash course and with a little bit of additional work it should be possible to aquire a certification.

What is TensorFlow / Keras ?

Tensorflow is an open-source machine learning library from Google and Keras is an abstraction layer / wrapper for Tensorflow and other similar libraries. Tensorflow allows the design of dataflow graphs where your input moves through a series of mathematical operations. Keras provides functionalities for neuronal networks.

So beginnt es…

Nachdem man in Corona-Zeiten auch privat etwas mehr Zeit vor dem Rechner verbringt habe ich mir vorgenommen meine IT-Hobbies/Projekte in einem Blog zu dokumentieren.

Since -due to corona- i have to spend my private time mostly in front of the computer, my plan is to post the IT-related parts of this activities in this blog.
