## `S3_STORAGE_PREFERRED_COPY_SOURCE`

Option | `S3_STORAGE_PREFERRED_COPY_SOURCE`
Description | Sets how to download segments from bucket storage when prefetching
Default | `false`

Sets how LogScale chooses segments to download from bucket storage when prefetching. If `S3_STORAGE_PREFERRED_COPY_SOURCE` is `false`, the prefetcher will only download segments that are not already on another host. Otherwise, it will download as many segments as necessary to follow the configured replication factor. This should help avoid excessive bucket downloads when nodes in the cluster have lots of empty disk space.
