Can elasticsearch do incremental backup of data，for example,The first day I backed up a batch of elasticsearch data, and the next day I also want to back up the data, but I will not do the backup of the data I did on the first day, could you please implement it

Another ideia is use snapshot to backup your data. You can pass as an argument the indexes that you want to backup in a PUT call.

[This blog post](https://www.elastic.co/blog/found-elasticsearch-snapshot-and-restore) is old, but still describes how snapshot and restore works quite well.
