Hi Team,

How can we perform incremental/delta snapshots?

If you run a new Snapshot against the same repository, it will be incremental as it will try to use the same segments (files).

That's the important part to note, so give it a new name.

Use the date command and add $now to the name.

@vinod_rao, you can write backup shell script as follows

```auto
#!/bin/sh
yest=$(date -d "-1 days" +"%Y.%m.%d")
echo $yest
curl -XPUT "<hostname>:9200/_snapshot/<repository_name>/dashboards-$yest?wait_for_completion=true&pretty" | while read output;
do
  echo $output
done

```

It automatically takes all the required pieces of previous backups.
