Backup Strategy for CDP Private Cloud

[#1]

We are on CDP 7.1.7 SP2 version

Can I ask what is the best strategy to backup the cluster? We are using 5 phyisical nodes (3 of which holds the actual HDFS data). What is a good strategy for backup?

1. Create another cluster that will act as replica (lower CPU and RAM)

2. In the same cluster, backup / to preserve the OS apps (CM etc.) and /data (HDFS)

hey, @Ben1996 what would like to backup is the HDFS data or anything else?

Also, I would like to let you 1 thing if possible add 1 more data node in your cluster as by default you have 3 as RF and if 1 DN goes down then you'll have only 2 DN alive which could be critical for business.

For backing up HDFS data you can create anther cluster with low resources and setup a BDR jobs on it to replicate data from PROD to DR cluster refer to the below link.

Thanks Rajat! Does that mean if 1 failed, the entire cluster will not be functional? Thank you for linking the replication manager, so it is essentially option 1 of what i previously thought of.
