[Question posted by a user on YugabyteDB Community Slack]

I noticed when i do backup /restore for single node i have no issue at all but for a multi-node cluster i would have issues with the backup. I see on the documentation regarding the tip below:

To get a snapshot of a multi-node cluster, you need to go into each node and copy the folders of ONLY the leader tablets on that node. Because each tablet-replica has a copy of the same data, you do not need to keep a copy for each replica.

Not sure what this means , how would i get ONLY the leader tablets on that node?

Lets say we have a 3-node cluster, i would just backup all the leader tablet data of the current node , then do the same for the next 2 . At the end, i would restore it by copying only the leader tablet data on its own respective node, then restoring it like that?

Based on the replication factor by default, or set for a tablespace explicitly, a tablet is replicated 3 times. You don't have to backup all copies. Just the tablet-leader data. When you restore, you restore the tablet-leader data 3 times to 3 different servers (assuming RF 3).

No. On restore, you'll need to copy to 3 replicas.
