System Center Configuration Manager landing page
Please be aware of a very important change required to your backup strategy in Configuration Manager 1511 (and later). As you know regular upgrades will be available for the product (every 4 months or so) and you will be able to upgrade using update packages in the "Updates and Servicing" node of the Administration > Cloud Services workspace.
Have a look at the new folder CD.Latest. This contains the source files that actually installed the current site.
Have a look inside - recognise the contents?
This folder will be required when you are recovering a failed site so it must be included in a backup strategy. Note that the built in backup maintenance task will back up this folder automatically. Also note that there is no point in backing up this folder once. It must be ongoing because, when upgrades are installed, Configuration Manager also updates the CD.Latest folder with the current files.
You can read about this change in the Backup and Recovery for System Center Configuration Manager document in the TechNet library.
This quote from that document issues us with a warning:
"If you do not have the correct CD.Latest folder and its contents available, you cannot recover a site that must be reinstalled".
Site recovery is actually started by running the Configuration Manager Setup Wizard from the CD.Latest folder.
I hope this information helps you to keep your Configuration Manager site safe. Until next time...
