Parameters

Response
The following fields are returned.
| Field | Description |
|---|---|
database_name |
The database name. |
table_name |
The table name. |
start_time |
The time of the earliest data encapsulated in the backup. Note that this only displays for incremental backups. For a full backup, this is NULL. |
end_time |
The time to which data can be restored. This is equivalent to the AS OF SYSTEM TIME of the backup. If the backup was not taken with revision history, the end_time is the only time the data can be restored to. If the backup was taken with revision history, the end_time is the latest time the data can be restored to. |
size_bytes |
The size of the backup, in bytes. |
create_statement |
New in v19.2: The CREATE statement used to create table(s), view(s), or sequence(s) that are stored within the backup. This displays when SHOW BACKUP SCHEMAS is used. Note that tables with references to foreign keys will only display foreign key constraints if the table to which the constraint relates to is also included in the backup. |
