Qlik Sense QVD / QVF Encryption (Qlik Sense Enterprise on Windows)

From Qlik Sense Enterprise on Windows September 2019 (the option became configurable via the QMC in November 2019), users have the option of enabling one or both of QVD and QVF encryption – adding at-rest protection from people who shouldn’t have access to your valuable files. This is enabled server-wide and applies to all content on the environment.

The big issue that I see is that any security office is going to require that any and all encryption is enabled – without understanding the issues this could cause.

Here’s the new DATA ENCRYPTION section under Service cluster in the QMC

AWS Lightsail snapshots – now automatic for Linux

As an update to my previous post on using lambda to automate snaphots, I’ve finally logged back into the Lightsail console and seen they have added a new feature – automatic snapshots.

There’s now an automatic snapshot section – note that the manual snapshots above are the 14 days dutifully maintained by the lambda script

It looks like the feature was added in October, based on the help site.

You’re able to change the time the snapshot is taken, but not the amount of history maintained

I won’t be switching from the lambda function as I require 14 days on Lightsail boxes, but if you’re happy with the following constraints, then it’s a great option:

  • Pre-set to 7 days of snapshot retention (no more, no less)
  • Must be set to run at a specific time (no triggers)
  • Available on Linux boxes only (no Windows as yet)

Remove (destroy) all variables in a Qlik Sense application

In QlikView, you had the ability to select multiple variables and delete them en-mass. In Qlik Sense, the UI permits you to undertake this activity one-by-one, and each takes two or three clicks.

This bookmarklet (Chrome only this time, not tried elsewhere) removes ALL variables from a Qlik Sense application by cheating the APIs used by the Qlik Sense client.
