 | 2 | += Inspect the metadata of a backup file  | 
 | 3 | +: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..  | 
 | 4 | +:page-role: enterprise-edition new-5.25  | 
 | 5 | + | 
 | 6 | +You can inspect the metadata of a database backup file using the `neo4j-admin backup inspect` command.  | 
 | 7 | + | 
 | 8 | +[[inspect-backup-command]]  | 
 | 9 | +== Command  | 
 | 10 | + | 
 | 11 | +The inspect command lists the metadata stored in the header of backup files.  | 
 | 12 | +This metadata primarily defines how backups are connected to form xref:backup-restore/online-backup.adoc#backup-chain[backup chains].  | 
 | 13 | +A backup chain is a sequence of one or more backup(s) logically connected.  | 
 | 14 | +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.  | 
 | 15 | + | 
 | 16 | +The metadata contains the following information:  | 
 | 17 | + | 
 | 18 | +* *Database*: database name of the database fragment that the backup includes.  | 
 | 19 | +* *Database ID*: a unique identifier that distinguishes databases (even with the same name).  | 
 | 20 | +* *Time*: time the backup was taken.  | 
 | 21 | +* *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).  | 
 | 22 | +* *Compressed*: indicates whether the backup data inside the backup file is compressed.  | 
 | 23 | +* *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.  | 
 | 24 | +* *Highest transaction ID*: similarly, this value indicates the last transaction ID stored in the backup file.  |

 | 178 | +=== Inspecting backup chains  | 
 | 179 | + | 
 | 180 | +A backup chain corresponds to a sequence of one or more backup(s) logically connected by their transaction IDs.  | 
 | 181 | +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:  | 
 | 182 | + | 
 | 183 | +[source,shell]  | 
 | 184 | +----  | 
 | 185 | +bin/neo4j-admin backup inspect /backups --show-metadata --latest-chain --database=london  |

 | 194 | +----  | 
 | 195 | + | 
 | 196 | +The result returns a chain of size two:  | 
 | 197 | + | 
 | 198 | +* The first backup is a full backup containing the store files within the transaction range [1,5].  | 
 | 199 | +* The second backup is a differential backup containing only the subsequent modifications to the store files.  | 
 | 200 | +Those modifications are materialised by a sequence of transactions to apply.  | 
 | 201 | +Its range is [6,6].  | 
 | 202 | + | 
 | 203 | + | 
 | 204 | +=== Inspecting a backup chain ending with a specific backup  | 
 | 205 | + | 
 | 206 | +To inspect a backup chain ending with a specific backup, use the `--latest-chain` option as follows:  | 
 | 207 | + | 
 | 208 | +[source,shell]  | 
 | 209 | +----  | 
 | 210 | +bin/neo4j-admin backup inspect /backups/london-2024-10-07T16-04-05.backup  --show-metadata --latest-chain  |

 | 219 | +----  | 
 | 220 | + | 
 | 221 | +[NOTE]  | 
 | 222 | +====  | 
 | 223 | +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_.  |
