Back up a Database Cluster
This page walks you through the steps to back up your database cluster. The process also applies to single-server instances.
Backing up a cluster is an online operation. Your database remains available during the backup.
You have access to the TigerGraph Linux user account on your cluster. All commands must be run from the TigerGraph Linux user.
You have provided valid configurations for database backup.
2.1. Data backup
To back up a database cluster, run the following command :
$ gadmin backup create <tag>
<tag> with a custom tag for the backup.
A timestamp is suffixed to the tag you provided to form the full tag of the backup.
If no tag is provided, the system uses the default
backup followed by the timestamp when the backup is created as the tag for the backup.
For example, run the following command to create a backup for a database cluster:
$ gadmin backup create weekly
This creates a backup file named
weekly-<timestamp> at the backup location you configured.
2.2. Metadata backup (Optional)
This step is only necessary if you are planning for an event where you need to restore the backup in another cluster.
Run the following command to create a backup for the metadata of a particular backup:
$ gadmin backup list <backup_tag> --meta
This produces a file called
metadata in the current path where the command is run.
Store this file in a secure location.
This file is required to restore the backup in another database cluster.
