Pruning DPM Replicas

There are times when, as a DPM administrator, you might want to prune disk-based replicas of data sources, either to save space or because of another reason entirely. As we’re currently experiencing an issue with DPM 2016 CU4 whereby replicas of filesystem data (disks/volumes/directories/shares) aren’t being pruned (the maintenance task calls a SQL procedure with […]

Thought for the day

Shamelessly stolen from the Core Rulebook of the Elite: Dangerous RPG: … when you’re out there in your ships, a canopy of stars above you, and not a living thing for a million miles all around, the light of a purple dwarf star glinting off the hull plates, and an unexplored galaxy stretching out in […]

Off-boarding Exchange Online users who have never had an on-prem mailbox

Wow. Sorry for the long title on this one folks, but allow me to continue. As regular readers of my occasional tech-tips posts will know, our organisation exists in a hybrid relationship with Exchange Online. Some users are in the cloud, some are on-premises as we migrate them. Occasionally a user will need to be […]

Large DPM databases

Had an on-going issue recently where one of our DPM servers seems to crash over night. Eventually I found an error in the log stating that the DPM server had lost connectivity to the DPMDB database in the SQL instance. I thought this was a little odd because we have three DPM servers which all […]

Exchange 2013 > Exchange 2007 mail relay issues

Had an interesting issue come to light in our Exchange environment recently. Before I go into it, I’ll give a bit of background on how we’re set up… Most of our organisation has mailboxes in an Exchange 2007 environment. There are some users and shared mailboxes in Exchange 2013, and this environment is in a […]

Exchange Online migrations and calendar permissions

We’re in the middle of migrating our on-premises Exchange organisation to Exchange Online. You see some odd things when you’re running a hybrid Exchange environment, but one of the oddest I’ve seen so far is a user being denied permission to edit or remove items in their own calendar after being migrated. Trying in Outlook […]

DPM, Previous Versions and Terminal Services

We use Data Protection Manager to allow end-users to perform self-service recovery on their own homes drives by using previous versions. This integrates with Active Directory to present the replica shares directly from the DPM server which performs the backup. It seems that the functionality of this tab is disabled by default on remote desktop […]

Some things that have been annoying me

I’ve had a bee in my bonnet about a few things just lately. I’ve been meaning to find the time to write up about each once, but frankly I couldn’t be bothered. I still mostly can’t so here they all are on one post instead. Real people don’t need encryption This statement was uttered by […]

Windows and long file names

Users can be a pain in the arse at times, especially when it comes to managing their file shares. We’ve had everything from users removing administrator groups and SYSTEM from the permissions list, stopping us from supporting them when they have issues and even backing up their files, to somehow creating file and folder structures […]

BizTalk 2016 Installer Crash

Had another weird one today while installing BizTalk Server 2016 on Server 2016 with SQL Server 2016. When applying the configuring to the server the installer crashed out while applying the BAM Portal settings. The event viewer had nothing useful to offer, only highlighting the particular DLL in question that had caused the error. The […]
