2. When trying to perform a restore of the SharePoint Site from a differential backup the job may fail with the below
error message:
AE9999: Unexpected Error. Exception Type: 'System.Data.SqlClient.SqlException', Message: This differential backup cannot be restored because the database has not been restored to the correct earlier state. RESTORE DATABASE is terminating abnormally.
Solution:
The key is that a differential backup is based on a particular full backup.
In order to restore a differential backup, you MUST restore the last full backup which was taken before that differential backup.
The problem can also occur if there is a FULL backup performed in between old FULL backup and the DIFF backup. Below are some backup consideration for Sharepoint 2010 and 2013.
You cannot perform a backup by using both SharePoint Server 2010/2013 and tools such as Microsoft SQL Server tools, Central Administration website, and so on. For example, if you perform a full backup using these tools, you may not be able to restore the differential backup job.
If you try to protect SharePoint Server 2010/2013 using the Agent for Microsoft SharePoint Server and other agents, such as Client Agent and Agent for SQL server, the SharePoint 2010/2013 data may be backed up more than once. To avoid this situation, you should exclude the SharePoint 2010/2013 database and files from the Client Agent and Agent for SQL Server backup job.
A Farm-level full backup can be followed by a Farm-level differential. However, you cannot do a Farm-level full backup followed by a Web Application full backup, and then a Farm Differential backup. In this case, the differential job would fail with an error message.
3. During Backup, we need to check for any orphaned features etc. In some situations we don't get any message pls find the below post.
