I have a classic question about snapshots in elasticsearch.
I make elasticsearch snapshots to some repository - for example, let it be some Network File System (NFS) or similar.
Later this snapshot from this network storage goes to other media - for example, tapes LTO or BD-ROM.
The question is simple:
There are 10 indexes in the repository.
What if I only want to restore 1 index?
Do I have to load the entire repository into NFS from the tape (some long term medium) and then recover only one index from elasticsearch?
Is there any idea that I need to retrieve only one index from the LTO/BD-ROM?
Limiting yourself to just the index you need can save you a lot of time.
