Error Code: 40:110 Client-side deduplication enabled job found Cache-Database and Deduplication-Database are out of sync

Backup jobs with Client-side Deduplication go pending

Symptoms

Backup jobs go pending with the following error message:

Error Code: 40:110 :
Client-side deduplication enabled job found Cache-Database and Deduplication-Database are out of sync. Job will be preceded by next resume.

Causes

This error message might appear due to one of the following reasons:

• Source-Side Deduplication Database (SSDB) is out of sync with the Deduplication Database (DDB) on the MediaAgent. When this occurs the SSDB has reference pointers (signature hash) that the central DDB doesn't have. Therefore the job(s) of the client associated to the SSDB go to a pending state.
• Deduplication data verification job marked invalid data blocks as bad.

Resolution

The jobs is automatically resumed for every 20 minutes. To manually resume the job, right-click the job and then click Resume.

Once the job resumes (automatically or manually ) the SSDB will automatically be created and repopulated as it processes signature hashes from the client to the MediaAgent.
