It happens that there is an average lifetime of the test base, there is a time agreed by all interested snapshot lives, but one of the environments for too long "lingers" in his picture, which does not remove and then it turns out to be useful to colleagues. And minus the minus gives a plus.

To argue that the site should always be available is maverick and banal, but 100% availability, although a mandatory requirement, is often still an inaccessible ideal. Now there are a lot of solutions on the market that promise maximum uptime or offer solutions to increase it, but their application is not enough, which does not always help, in some cases even lead to increased risks and reduced project availability. In this article, we will go over the classic mistakes that we constantly face. Most of the problems are elementary, but people allow them again and again.

Data warehouse performance: new digits

Data warehouse performance: new digitsIn our previous post, we shared our measurements of hypervisor performance after installing patches against the vulnerabilities of Meltdown and Specter. Today it's time to talk about the performance of the data warehouse.
 
 
 
 
Thanks to the optimizations of VzKernel and its recompilation with the "Retpoline" option, we replaced the vulnerable machine code sequences and almost completely eliminated the performance problems caused by the need to protect the hypervisor from vulnerabilities in Intel processors. As a result, the decrease in productivity was reduced to 1-2%. However, against this ...

One of the most problematic tasks for a regular user is a backup under Windows, which would ensure the closure of the following questions:
 
 
 
fast (ideally in the background);
 
would save both the current version of the files, and the previous ones;
 
The file vault would not be accessible to viruses or natural disasters such as the destruction of a carrier or its theft;
 
the content of the backup copy would be accessible only to the user, i.e. was password-protected.
 
 
There are many suggestions for this, but none of them does the task completely. Easy easy copying does not give speed...
