Hi All,
I need an assistance,
Setup environment:
Server’s
-Replica 1
-Replica 2
Arbiter - acting as heartbeat
Does anyone have a experience how to backup this setup? And also in case of catastrophic failure you loose all the servers. How do you rebuild this environment and restore your data?
You might find the relevant procedures in these pages:
MongoDB Backup Methods for general overview on supported backup methods, along with links to more specific method’s page
Restore a Replica Set from MongoDB Backups for restoring your backup into a new replica set
However I find this sentence in your post curious:
Arbiter - acting as heartbeat
What do you mean by “heartbeat”, exactly? An arbiter in a replica set functions as a tiebreaker for primary election. They allow you to have a primary in case your secondary is down in a PSA (primary-secondary-arbiter) setup. However they also come with their own disadvantages (cannot confirm majority write, writes to the primary can be rolled back, etc.). This setup is quite inferior to a PSS (primary-secondary-secondary) setup in terms of high availability & data integrity, so you might want to deploy them with caution and know their limitations.
Best regards
Kevin
