I’m trying to restore a backup from a Weaviate class an another node. This fails with errors like:  
“resolve node name “0d83d09dea6c” to host’”

It looks like the hostname from the original node is embedded in the backup and the restore process fails because it tries to resolve the old hostname!?

Any idea how I can get this working?

Hi! Welcomet to our community 🤗

**TL;DR**  
set environment variable  
CLUSTER\_HOSTNAME=0d83d09dea6c

Thanks for your reply.

After setting CLUSTER\_HOSTNAME I can restore the backup on a new node.

Now when I create a backup on the new node the ID “0d83d09dea6c” is used again. This means I’ll have to stick to the ID as long as I’m doing backups. This is strange but ok.

Is it recommended to set CLUSTER\_HOSTNAME to something like a logical node name from the beginning?

It is. Was this an old deployment being upgraded, right?
