Elasticsearch backup not recovering as intended

We are running ES 14.1 and restored data from our backup folder,
started the master and then nodes.
Cluster health shows status as green, but it only brought 2/4 indices.
In addition, the 2 that were brought online only contain 3 and 4 docs
each.
The entire data/ folder on each of the three nodes is approx. 80mb,
the data size is small but that weren't indexing too much data to
begin in first place..

any thoughts on how we can go about the restore?
