7.6 is very much past [EOL](https://www.elastic.co/support/eol), you should upgrade as a matter of urgency.

It's not clear what you mean here, can you add a bit more detail on what you want?

I have ES 7.6.2 version and my cluster with 9TB.  
It's feasible/recommendable to perform optimal snapshot of my cluster with the slm policy ?  
Is there another more efficient tool?  
Is there any cluster size limit for snapshot with the slm policy?  
Thanks

I would also recommend that you upgrade, at least to version 7.17.4.

SLM helps schedule and automate the snapshot/restore API, which is the **only** supported method of backing up an Elasticsearch cluster.

I am not aware of any better solution to schedule and manage the snapshot/restore process.

No. The first snapshot you create will take a while to complete as a lot of data need to be copied, but once that is done only new segments will be copied in subsequent snapshots, which generally results in a lot less data being copied every time.
