Full history node restore from backup

[PaulMoney]

Hello,

I have a full-history proxy node, and now I need to deploy another instance of a full-history proxy node using a backup taken from the node I already have.

I’ve read the documentation here — https://xrpl.org/docs/infrastructure/configuration/data-retention/configure-full-history — about database dumps, but I couldn’t find information on which folders or files I should include in the backup.

Could you please explain in more detail how I can start a new node from a database backup? Thank you.

Update: For now, I have created a backup of the nudb folder and specified this backup folder in the import stanza of rippled.cfg. I saw the following log lines:
