I have 2 node elasticsearch cluster version 7.4.

- CPU 32
- Memory 250G
- Disk IOPS 50K IOPS (SSD)
- Heap 32GB
- Snapshot size 3TB

since its a bigger instance, how to change the config files to restore the snapshot in the fastest way?

You can increase [max\_restore\_bytes\_per\_sec](https://www.elastic.co/guide/en/elasticsearch/reference/7.4/modules-snapshots.html#snapshots-repositories) , [indices.recovery.max\_bytes\_per\_sec](https://www.elastic.co/guide/en/elasticsearch/reference/7.4/recovery.html#_peer_recovery_settings) for example increasing from 40mb to 200mb per seconds to be safe, maybe 500mb and [cluster.routing.allocation.node\_concurrent\_incoming\_recoveries](https://www.elastic.co/guide/en/elasticsearch/reference/7.4/shards-allocation.html#_shard_allocation_settings) from 2 to 5 for example given its SSD. The default values allow not to use too much resources just for recovery / restore which would cause other features to slow down hence those settings can be tuned up and back down as appropriate
