OneDrive, Placeholders, and shared PCs.

OneDrive now with Files On Demand

At their annual Build conference, Microsoft announced that OneDrive was getting a new feature called “Files On Demand”- basically a replacement for the placeholders feature that was present in Windows 8.1’s OneDrive client. The official Office blog goes into more detail about the new features, and there’s a detailed writeup by Paul Thurrott which also includes the history of OneDrive placeholders, but I’d like to discuss the advantages for the education vertical- in particular Student PC labs.

Microsoft kindly offer OneDrive to University students for basically nothing, so it sounds like an ideal replacement for traditional on-premises network file-shares. Rather than the IT department struggling to provide 50 or 100GB of space per student from their budget, they could just point students at the 1 TB of disk Microsoft is providing for free.

Sync Good

A sink. Not a sync

Not this kind of sync


With a single regular user and enough local hard disk space a sync client without placeholders is fine. All the users files are synced to the local disk and available instantly whenever they are required. The selective sync in the current Windows 10 client helps on devices with smaller disks, but is still only really beneficial on a PC with a single regular user.

Sync Bad

On the students personal devices this works great- we’re back at this 1 user:1 device ratio. However in a student PC lab environment there are potentially hundreds of desktops and each of tens of thousands of users could log into any one at any time. We have a x,000:1 user:device ratio. Students don’t want to login to a machine at the start of a class and then wait whilst half a terabyte of data they don’t need syncs before document they need appears. Additionally IT don’t want to have to tidy up all this synced data after every user logs off.

Student Computer Labs

It’s technically possible (although can be a little fiddly depending on your infrastructure) to map your OneDrive to a drive letter using WebDav and then access it as you would a traditional “Home” drive, but this is unsupported by Microsoft. There are third party solutions that will map the drive, basically providing a front end and a support contract around this, but they’re often costly and may require infrastructure changes.

Placeholders FTW

Placeholders (or “Files On Demand”) is the ideal solution here. The student now sits down at the shared lab machine and all their files are listed. They then open the file of their choice and there’s an invisible, seamless, download in the background. When they save the file it’s synced back to the cloud. The user is happy as they no longer has to wait for all their files to sync before they can work and can take advantage of the large capacity (and sharing facilities too). IT are happy because they don’t have to fund (and support, maintain) as much storage.

I know many IT Professionals working in Higher Education will be looking forward to this release in the autumn.

Microsoft Future Decoded 2015

November 2015 saw the return of Microsoft’s Future Decoded event to the ExCel Center in London. I didn’t make it last year (it was a week after TechEd Europe and I was all Microsofted out!) so I’ve been looking forward to the Tech Day of this event since the registration notice back in May. This is my summary of the day. Continue reading

Hybrid Identity Management

Last Thursday I spent the day with Microsoft in London finding out about their latest developments in mobile working strategy, data protection, and BYOD integration at an Enterprise Mobility Workshop. I took pages of notes (OneNote was once again a winner) but the session I’m going to focus on in this post was around Hybrid Identity Management.

The Microsoft Hybrid Identity Management solution is (unsurprisingly) based around Active Directory and it’s cloud cousin Azure AD, and this is core to the entire Enterprise Mobility piece. The subject kept coming back in later sessions during the workshop- Azure AD was a real lynchpin of this whole day- and I got the impression that it’s vital that this is done right if any Mobility solution is going to work.

70-410 Installing and Configuring Windows Server 2012R2

I sat, and passed, the Microsoft 70-410 exam in Windows Server 2012R2 last week. Whilst I’m not going to report everything on the test (both because I’m not allowed to, and because I can’t remember all the details) hopefully this post will provide a few pointers for others studying for the exam.

Microsoft UK Tech.Days Windows 8 Camp

2013-04-17 15.36.58Held at the De Vere New Place near Southampton this was a very different experience to the other Microsoft events I have been to in the past. Firstly the audience was much smaller, more like 60 than 600 attendees. Also, this wasn’t in a lecture room or a darkened cinema, but the room was arranged with us sat at circular tables, (with power for laptops) and the whole day was much more interactive.
