| = Inspect the metadata of a backup file | ||
| :description: This section describes how to inspect the metadata of backup files. Metadata are information like the database name, the backup compression, the transaction range that the backup contains etc.. | ||
| :page-role: enterprise-edition new-5.25 | ||
|
|
||
| You can inspect the metadata of a database backup file using the `neo4j-admin backup inspect` command. | ||
|
|
||
| [[inspect-backup-command]] | ||
| == Command | ||
|
|
||
| The inspect command lists the metadata stored in the header of backup files. | ||
| This metadata primarily defines how backups are connected to form xref:backup-restore/online-backup.adoc#backup-chain[backup chains]. | ||
| A backup chain is a sequence of one or more backup(s) logically connected. | ||
| The order of the sequence guarantees that when replayed (see xref:backup-restore/restore-backup.adoc[restore] or xref:backup-restore/aggregate.adoc[aggregate]), the store and the transaction data are consumed in a consistent manner. | ||
|
|
||
| The metadata contains the following information: | ||
|
|
||
| * *Database*: database name of the database fragment that the backup includes. | ||
| * *Database ID*: a unique identifier that distinguishes databases (even with the same name). | ||
| * *Time*: time the backup was taken. | ||
| * *Full*: indicates whether it is a full backup (i.e. initial backup containing the store files) or a differential backup (i.e. subsequent backup containing only the transactions to be applied to the store files). | ||
| * *Compressed*: indicates whether the backup data inside the backup file is compressed. | ||
| * *Lowest transaction ID*: when the backup is full, this value is always 1, and when it is a differential backup, the value corresponds to the first transaction ID the backup starts with. | ||
| * *Highest transaction ID*: similarly, this value indicates the last transaction ID stored in the backup file. | ||

|
|
||
| [source,shell] | ||

| === Listing the metadata of the backup files | ||
|
|
||
| The following command lists the backup files' names along with their respective metadata: | ||
|
|
||
| [source,shell] | ||
| ---- | ||
| bin/neo4j-admin backup inspect /backups --show-metadata --empty | ||
| ---- | ||
|
|
||
| The `--empty` option is used to include the empty backups. | ||
| An empty backup is created when a database is backed up but no new data exists. | ||
| Empty backups are used to record the backup history. | ||
|

|
|
||
| === Listing the latest backups | ||
|
|
||
| To list only the most recent backups performed for each database, use the `--latest-backup` option. | ||
|
|
||
| [source,shell] | ||
| ---- | ||
| bin/neo4j-admin backup inspect /backups --show-metadata --latest-backup | ||
| ---- | ||
|
|
||

| ---- | ||
| | FILE | DATABASE | DATABASE ID | TIME (UTC) | FULL | COMPRESSED | LOWEST TX | HIGHEST TX | | ||

| ---- | ||
|
|
||
| === Inspecting backup chains | ||
|
|
||
| A backup chain corresponds to a sequence of one or more backup(s) logically connected by their transaction IDs. | ||
| To inspect the backup chains of a given database, use the `--latest-chain` option and the `--database` option with the database whose backup chain you want to inspect: | ||
|
|
||
| [source,shell] | ||
| ---- | ||
| bin/neo4j-admin backup inspect /backups --show-metadata --latest-chain --database=london | ||
| ---- | ||
|
|
||
| .Example output | ||
| [result] | ||
| ---- | ||
| | FILE | DATABASE | DATABASE ID | TIME (UTC) | FULL | COMPRESSED | LOWEST TX | HIGHEST TX | | ||
| | file:///backups/london-2024-10-07T16-04-05.backup | london | d4dae73c-dfef-4d28-88cd-fe6cc88ddca1 | 2024-10-07T16:04:05 | false | true | 6 | 6 | | ||
| | file:///backups/london-2024-10-07T16-03-51.backup | london | d4dae73c-dfef-4d28-88cd-fe6cc88ddca1 | 2024-10-07T16:03:51 | true | true | 1 | 5 | | ||
| ---- | ||
|
|
||
| The result returns a chain of size two: | ||
|
|
||
| * The first backup is a full backup containing the store files within the transaction range [1,5]. | ||
| * The second backup is a differential backup containing only the subsequent modifications to the store files. | ||
| Those modifications are materialised by a sequence of transactions to apply. | ||
| Its range is [6,6]. | ||
|
|
||
|
|
||
| === Inspecting a backup chain ending with a specific backup | ||
|
|
||
| To inspect a backup chain ending with a specific backup, use the `--latest-chain` option as follows: | ||
|
|
||
| [source,shell] | ||
| ---- | ||
| bin/neo4j-admin backup inspect /backups/london-2024-10-07T16-04-05.backup --show-metadata --latest-chain | ||
| ---- | ||
|
|
||
| .Example output | ||
| [result] | ||
| ---- | ||
| | FILE | DATABASE | DATABASE ID | TIME (UTC) | FULL | COMPRESSED | LOWEST TX | HIGHEST TX | | ||
| | file:///backups/london-2024-10-07T16-04-05.backup | london | d4dae73c-dfef-4d28-88cd-fe6cc88ddca1 | 2024-10-07T16:04:05 | false | true | 6 | 6 | | ||
| | file:///backups/london-2024-10-07T16-03-51.backup | london | d4dae73c-dfef-4d28-88cd-fe6cc88ddca1 | 2024-10-07T16:03:51 | true | true | 1 | 5 | | ||
| ---- | ||
|
|
||
| [NOTE] | ||
| ==== | ||
| In this case, the `--database` option is unnecessary because the database identifier is part of the metadata stored in the header of the backup file _london-2024-10-07T16-04-05.backup_. | ||
