Should Roaming User Profiles Be Backed Up?

This may seem like a silly question, but whether or not to include roaming user profiles in your enterprise backup solution may greatly affect both the performance and the cost of that solution. With that in mind, it is only logical to pose the question if the content stored in user profiles is valuable enough to be backed up. Continue reading ‘Should Roaming User Profiles Be Backed Up?’


New Articles, Tools, Tips and Tricks: Windows, Hyper-V, Citrix, PowerShell and Application Streaming / App-V

Windows

Beginning with Vista, when formatting a drive the entire disk is overwritten with zeroes. While this is good for end users who like to wipe all data prior to selling or throwing away a disk drive, SAN-based volumes should not be formatted like this. Perform a quick format instead. But if you want to make sure the data is really gone – no need for “secure erase” programs any more! The need for multiple overwrites is a myth.

What is a CTP Meeting all about?

I just returned from my first CTP (Citrix Technology Professional) meeting and thought I might share a few experiences.

The meeting took place in one of Citrix’s headquarter buildings in Fort Lauderdale, Florida. The meeting itself ran over two days, which means that most attendees were away from home and work for four. While that is certainly nice to know, the question you probably have is: “What does actually happen during such a meeting?” Continue reading ‘What is a CTP Meeting all about?’


Virtualization – Old Hat?

Although humans in general and members of its subspecies “marketing manager” in particular tend to treat currently “hot” topics as new and revolutionary, they only rarely are. In fact, “new” should be considered as in “new wine in old bottles” rather than in “did not exist before”. Take virtualization. Although the topic of the day seems to be cloud computing, virtualization can probably still be called “hot” (especially since a cloud also is a kind of virtualization). But is it new? Judge for yourself: Below I have compiled a list of boring old technologies that employ virtualization. Continue reading ‘Virtualization – Old Hat?’
