hi all... i am working on a project that puts its results to elastic search during running on a server... my data is growing and i want to save my elastic search data in a new remote server in order to move whole data from entire server to new remote server and continue there. As i read, i should create repository and take snapshot...i did it locally on my entire server by creating repository, setting path.repo in .yml and taking snapshot! The problem is that, i want to backup my data on a remote server (not locally) in order to continue on it... i should say that, i am very new at elastic search world, so please guide me in details... i need your fast replies, thanks a lot... Best regards... ---

I have been succesfully using elasticdump to move indices from cluster to cluster or to create daily backups of my elasticsearch data > **[elasticdump](https://www.npmjs.com/package/elasticdump)** > > import and export tools for elasticsearch ---

Reindex API can read old cluster and index in the new cluster ---

@dadoonet thanks for your reply... i used Reindex API... it seems that there is a problem about some data types, because i faced with this error and reindex process is not completed: "error" : { "root\_cause" : [ { "type" : "status\_exception", "reason" : "body={"error":{"root\_cause":[{"type":"search\_context\_missing\_exception","reason":"No search context found for id [41875]"},{"type":"search\_context\_missing\_exception","reason":"No search context found for id [41874]"},{"type":"search\_context\_missing\_exception","reason":"No search context found for id [41870]\ ........... } there is different types of data in my results such as string, date, id , .... does it relate to this error? i have another question; my data is very large, more than 50 G... is there any limit about size in remote Reindex method? ---

Most likely you got a timeout or something while running the scroll. > my data is very large, more than 50 G. That might explain. It depends on the size of your docs. As per [documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-reindex.html), I can read: > Reindexing from a remote server uses an on-heap buffer that defaults to a maximum size of 100mb. If the remote index includes very large documents you’ll need to use a smaller batch size. The example below sets the batch size 10 which is very, very small. May be change the size. Or look at slicing options??? ---
