My scheduled Incremental Job keeps failing, why?

This can happen where you're backing up advanced services using the Server Edition, with technologies such as:

- Exchange Server
- SQL Server
- SharePoint
- Active Directory

This issue is normally caused because when you first setup this service, a FULL Backup is taken. Thereafter an Incremental Backup is taken. You'll often have a weekly "Full" backup with "Incrementals" during the week.

To perform an incremental, the system will place a marker in the database(s) of those tools to indicate where it has backed up to - then when you run an incremental, it gets that marker, and backs up everything that is new, and changed since that point. Then sets a new marker. When you perform a full backup, there is no marker - as it is not a "point in time" but a full copy.

This works absolutely fine when only one system is performing backups. However if you have a second system take backups, this will cause issues. We most commonly see this issue where a customer has taken some other type of backup (often a one off SQL Backup using the native management tools for example).

The normal way to resolve this is to perform a FULL Backup again of the data that is failing - using our system, after which routine backups should run normally again.
