I've CDP 7.3.1 private cloud cluster (3 master, 1 manager, 1 edge & 5 slaves) . I'm wondering how can I secure a backup/restore point for it. Is it technically right and "supported by Cloudera" if I take a VM snapshots on machines level for master nodes ? Should it be cold (offline) backup (stop or pause the cluster operations) to ensure of consistencies between distributed services on master nodes?
Thanks for your response! "May I know if you are planning to backup the HDFS data or the host data ? " Yes, I need to backup HDFS data as well.
"snapshot can be a good approach" , is it supported by Cloudera? I'm wondering if a heavy operational cluster with a distributed master services on master nodes can be done smoothly without facing dependencies issues, especially preserving a one-state for all master services across all master nodes at the exact same time while taking snapshot can't be granted easily, especially if we decide it would be a hot snapshot (not cold).
