I experimented with mounting a backup image from a particular backup point on a job, using the Backup software.
This worked fine, and a new drive letter was created which could be browsed directly via windows explorer.
I was not clear how to dismount the image, and the documentation said that it would only remain mounted until a reboot anyway.
In fact, after rebooting, the image remained mounted in error even if the backup disk was not available (obviously it could not be fully browsed). I managed to remove it consistently by de-assigning its drive letter in disk management, then rendering it offline in disk management, and then using device manager to delete the UIM device for the mounted image, which appeared under disk devices. This worked ok providing all the steps were done in the right order, otherwise it appeared to remain around after a reboot.
After trying again in the backup software, I found it was a simple user error – the mount screen allows selection of a drive letter, and if one is already selected you can select “None” again to remove it and dismount the image. This was not immediately obvious the first time around – I failed to notice that “None” was available in the list as it was hidden and you need to explicitly scroll to the very top of the list to see it.
Once I dismounted the image this way, it worked immediately and completely removed the image and the device even without a reboot.
