Rollup then backup indices

[lstoneir (lal ston)]

Hi there,
I have a elastic cluster with 5 nodes (each node 1TB)
I want to backup my indices, but I dont have enough resources to backup all indices.
I want to rollup indices for example my main indices are hourly, I want to rollup them to Daily format and then backup up the rolled up indices.

How can i do this? can any one tell the details ?

thanks
