:description: How to create a database using a seed from URI.
3+
4+
[[database-seed-uri]]
5+
= Create a database using seed from URI
6+
7+
This method seeds all databases with an identical seed from an external source, specified by the URI.
8+
9+
The URI of the seed is specified when the `CREATE DATABASE` command is issued:
10+
11+
[source, cypher, role="noplay"]
12+
----
13+
CREATE DATABASE foo OPTIONS {existingData: 'use', seedURI:'s3://myBucket/myBackup.backup'}
14+
----
15+
16+
Download and validation of the seed is only performed as the new database is started.
17+
If it fails, the database is not available and it has the `statusMessage`: `Unable to start database` of the `SHOW DATABASES` command.
18+
19+
[source, cypher, role="noplay"]
20+
----
21+
neo4j@neo4j> SHOW DATABASES;
22+
+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
23+
| name | type | aliases | access | address | role | writer | requestedStatus | currentStatus | statusMessage | default | home | constituents |
24+
+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
25+
| "seed3" | "standard" | [] | "read-write" | "localhost:7682" | "unknown" | FALSE | "online" | "offline" | "Unable to start database `DatabaseId{3fe1a59b[seed3]}`" | FALSE | FALSE | [] |
26+

To determine the cause of the problem, it is recommended to look at the `debug.log`.
30+
31+
[NOTE]
32+
====
33+
Starting from Neo4j 2025.01, seed from URI can also be used in combination with xref:database-administration/standard-databases/create-databases.adoc[`CREATE OR REPLACE DATABASE`].

== Seed providers in Neo4j
38+
39+
The seed can either be a full backup, a differential backup (see <<cloud-seed-provider, `CloudSeedProvider`>>), or a dump from an existing database.
40+
The sources of seeds are called _seed providers_.
41+
42+
The mechanism is pluggable, allowing new sources of seeds to be supported (see link:https://www.neo4j.com/docs/java-reference/current/extending-neo4j/project-setup/#extending-neo4j-plugin-seed-provider[Java Reference -> Implement custom seed providers] for more information).
43+
44+
The product has built-in support for seed from a mounted file system (file), FTP server, HTTP/HTTPS server, Amazon S3, Google Cloud Storage, and Azure Cloud Storage.
45+
46+
[NOTE]
47+
====
48+
Amazon S3, Google Cloud Storage, and Azure Cloud Storage are supported by default, but the other providers require configuration of xref:configuration/configuration-settings.adoc#config_dbms.databases.seed_from_uri_providers[`dbms.databases.seed_from_uri_providers`].

66+
67+
Starting from Neo4j 2025.01, the `URLConnectionSeedProvider` does not support `file`.
68+
// This is true for both Cypher 5 and Cypher 25.

** `azb:`
78+
79+
The `CloudSeedProvider` supports using xref:backup-restore/modes.adoc#differential-backup[differential backup] files as seeds.
80+
With the provided differential backup file, the `CloudSeedProvider` searches the directory containing differential backup files for a xref:backup-restore/online-backup.adoc#backup-chain[backup chain] ending at the specified differential backup, and then seeds using this backup chain.

==== Support for seeding up to a date or a transaction ID
126+
127+
Starting from Neo4j 2025.01, the `CloudSeedProvider` supports seeding up to a specific date or transaction ID using the `seedRestoreUntil` option.
128+
129+
[role=label--new-2025.01]
130+
Seed up to a specific date::
131+
132+
To seed up to a specific date, you need to pass the differential backup, which contains the data up to that date.
133+
+
134+
[source,shell]
135+
----
136+
CREATE DATABASE foo OPTIONS { existingData: 'use', seedURI: 's3://myBucket/myBackup.backup', seedRestoreUntil: datetime("2019-06-01T18:40:32.142+0100") }
137+
----
138+
+
139+
This will seed the database with transactions committed before the provided timestamp.
140+

143+

CREATE DATABASE foo OPTIONS { existingData: 'use', seedURI: 's3://myBucket/myBackup.backup', seedRestoreUntil: 123 }
149+
----
150+

151+
This will seed the database with transactions up to, but not including transaction 123.

156+
157+
// When Cypher 25 is released, we have to label this section 'Cypher 5' as this functionality is only available in Cypher 5.
158+
159+
The `S3SeedProvider` supports:
160+
161+
** `s3:` label:deprecated[Deprecated in 5.26]
162+
163+
164+
[NOTE]
165+
====
166+
Neo4j comes bundled with necessary libraries for AWS S3 connectivity.
167+
Therefore, if you use `S3SeedProvider`,`aws cli` is not required but can be used with the `CloudSeedProvider`.
168+
====
169+
170+
The `S3SeedProvider` requires additional configuration.
171+
This is specified with the `seedConfig` option.
172+
This option expects a comma-separated list of configurations.
173+
Each configuration value is specified as a name followed by `=` and the value, as such:
174+
175+
[source, cypher, role="noplay"]
176+
----
177+
CREATE DATABASE foo OPTIONS { existingData: 'use', seedURI: 's3://myBucket/myBackup.backup', seedConfig: 'region=eu-west-1' }
178+
----
179+
180+
`S3SeedProvider` also requires passing in credentials.
181+
These are specified with the `seedCredentials` option.
182+
Seed credentials are securely passed from the Cypher command to each server hosting the database.
183+
For this to work, Neo4j on each server in the cluster must be configured with identical keystores.
184+
This is identical to the configuration required by remote aliases, see xref:database-administration/aliases/remote-database-alias-configuration.adoc#remote-alias-config-DBMS_admin-A[Configuration of DBMS with remote database alias].
185+
If this configuration is not performed, the `seedCredentials` option fails.
186+
187+
[source, cypher, role="noplay"]
188+
----
189+
CREATE DATABASE foo OPTIONS { existingData: 'use', seedURI: 's3://myBucket/myBackup.backup', seedConfig: 'region=eu-west-1', seedCredentials: [accessKey];[secretKey] }
190+
----
191+
Where `accessKey` and `secretKey` are provided by AWS.
