I have a question on how to back up Dremio

1

Hello,

When I try to back up Dremio on the coordinator node, as described in the documentation Back up Dremio | Dremio Documentation, I encounter the following error:

  • KVFormatter is not supported for this KVStore while trying to backup dremio

I’m not sure what I should do or how to proceed with the update.

Has anyone encountered this issue before, or can advise on how to resolve it?

@raaz19 When running dremio-admin, I assume Dremio is up. Can you paste the command you are using to kick off the backup? Also, can you try to run the backup to a different folder? (Other than /tmp)

yes sure @balaji.ramaswamy ,

here is an example: /dremio-admin backup -u dremio -p dremio123 -d /tmp/backup

also i tried to run the backup on another folder ‘~/backup‘ still have the same issue
