Elasticsearch snapshot supported on a non-shared filesystem?

Elastic Stack Elasticsearch
1

Acc to elastic 6.8 docs - https://www.elastic.co/guide/en/elasticsearch/reference/6.8/modules-snapshots.html, it is mentioned that - "we can take a snapshot of individual indices or of the entire cluster and store it in a repository on a shared filesystem.
From this doc, I understand that in order to create snapshots, we mandatorily need a shared file-system only.

However, browsing throught the recent versions of the docs, (https://www.elastic.co/guide/en/elasticsearch/reference/current/snapshot-restore.html), there is no mention of this hard requirement.
So, has the behaviour changed? Are elasticsearch snapshots supported on non shared-filesystems as well for ES 7.x ?

Hi,

The documentation layout has changed. The information you are looking for is stored here:

No, a shared file system is still required.

A simple alternative is a standalone Minio installation too, along with the repository-s3 plugin.

Not necessary. If you have a single-node cluster (for your testing purposes), you can create snapshots in local file-system as well. I tested this on 6.8.6 and I have used this before on 5.x as well for my testing purposes. Haven't tried with 7.x but I guess the same behaviour holds true.

The aim of shared filesystem is so that multiple nodes can access the same shared repository.
