DPM2016 CU4 Fix

I’ve noted in other recent posts on DPM that we have been experiencing issues with the latest release of Data Protection Manager 2016 CU4. The main issue has been that when the overnight maintenance jobs run to remove expired replicas from storage, the job causes a service crash when trying to remove some disk/volume backups. […]

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 […]

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 […]

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 […]

SQL Server SSPI Errors

Wow. Its been a while since an update has appeared here, huh? Well, I had an interesting problem at work the other day and I thought I’d share the solution. A new application is being installed and tested which uses an MSSQL database for its internal information management. Integrated security is used based on a […]
