# Single Node Installs: Storage and Backup Guidelines ### General storage recommentations for single-node instances * `/data` is where the standalone deployment installs PostgreSQL data and Element Deployment data. It should be a distinct mount point. * Ideally this would have an independent lifecycle from the server itself * Ideally this would be easily snapshot-able, either at a filesystem level or with the backing storage ### Adminbot storage: * Files stored with uid=10006/gid=10006, default config uses `/data/element-deployment/adminbot` for single-node instances * Storage space required is proportional to the number of user devices on the server. 1GB is sufficient for most servers ### Auditbot storage: * Files stored with uid=10006/gid=10006, default config uses `/data/element-deployment/auditbot` for single-node instances * Storage space required is proportional to the number of events tracked. ### Synapse storage: * Media: * File stored with uid=10991/gid=10991, default config uses `/data/element-deployment/synapse` for single-node instances * Storage space required grows with the number and size of uploaded media. For more information, see [ESS Sizing](https://ems-docs.element.io/books/element-on-premise-documentation/page/ess-sizing) ### Postgres (in-cluster) storage: * Files stored with uid=999/gid=999, default config uses `/data/postgres` for single-node instances ### Backup Guidance: * **Adminbot**: * Backups should be made by taking a snapshot of the PV (ideally) or rsyncing the backing directory to backup storage * **Auditbot**: * Backups should be made by taking a snapshot of the PV (ideally) or rsyncing the backing directory to backup storage * **Synapse Media**: * Backups should be made by taking a snapshot of the PV (ideally) or rsyncing the backing directory to backup storage * **Postgres (in-cluster)**: * Backups should be made by `kubectl -n element-onprem exec -it postgres-synapse-0 -- sh -c 'pg_dump -U $POSTGRES_USER $POSTGRES_DB' > synapse_postgres_backup_$(date +%Y%m%d-%H%M%S).sql` * **Postgres (external)**: * Backup procedures as per your DBA * **Configuration**: * Please ensure that your entire configuration directory (that contains at least `parameters.yml` & `secrets.yml` but may also include other sub-directories & configuration files) is regularly backed up * The suggested configuration path in Element's documentation is `~/.element-onpremise-config` but could be anything. It is whatever directory you used with the installer.
