Sythetic full Index restore

Hello,

We have a client running file system level backups. Recently we associated it with a new storage policy and ran fresh full backups expecting a new Index will be created for that job.

Running Synthetic-full backup ( after few incremental backups ) triggers Index restore job from the previous storage policy where the copy data paths were on a different media agent.
The Index restore job fails as the communication between the current used media agent and previous one is blocked.

Any Idea how to force the creation of new Index or to avoid the reference to the previous Index ?

 

Thanks

@TNO

You mentioned a new Storage Policy, I would assume a new DDB and new Index Cache as well correct?

New MAs combined with new Fulls (New DDB and New Index) should have not asked for Index Restore. Can you check the job events tab and share logs as well. Are you sure this is all brand new or the new storage policy was created using a existing DDB (with old MAs?)

Hi ​@dude 

Old and new policies use different media agents and differeent DDB engines. Old one is a ‘classic’ media agent, new one is an HSX cluster.

I’ve went through the logs, I don’t any reference to the ‘Index restore’ that is triggered.

Hi ​@TNO,

 

You can try to create a new backupset and subclient and try the job. 

Note: With respect to licensing, capacity usage is calculated based on the application size of the most recent full or synthetic full backup for each subclient. As a result, this configuration may lead to an increase in capacity consumption.

Wasim
