MV_BACKUP_HISTORY

This view stores information about backups that have been made.

Column

Description

BACKUP_ID

A unique identifier for the backup.

CLUSTER_NAME

Name of the workspace that carried out the backup.

CLUSTER_ID

Unique id that can identify a workspace (see show workspace id).

DATABASE_NAME

Name of the database that was backed up.

START_TIMESTAMP

Timestamp at which the backup started.

END_TIMESTAMP

Timestamp at which the backup completed.

NUM_PARTITIONS

Number of partitions for the backup.

BACKUP_PATH

Path to where the backup file was placed after backup completed.

CHECKSUM

Concatenated CRC32C checksum of all backup files.

STATUS

Status of backup - Success or Failure.

SIZE

For full backups: size of all backup files, in megabytes.

For incremental backups: size of the changes (the incremental differences), in megabytes.

INCR_BACKUP_ID

A unique identifier for an incremental backup. If the backup is a full backup instead of an incremental backup, incr_backup_id is NULL.

TYPE

Possible values are FULL, INCR_INIT, INCR_DIFF, SPLIT_PARTITIONS, or an empty string. An empty string indicates that the type of backup is unknown because the backup was performed in earlier versions of SingleStoreDB Cloud, when the backup type was not recorded in the MV_BACKUP_HISTORY table.

TAGS

The values of TAGS parameter if it is specified in the BACKUP DATABASE command.

SERVER_VERSION

The SingleStoreDB Cloud version.

MEMORY_USAGE

The amount of memory (MB) used by the database before performing a backup.

IMPLEMENTATION

The type of backup: Lockfree or Original.

LOCKFREE_TIMESTAMP

The global logical timestamp used to perform the backup if implementation is Lockfree.

Example - this query shows the last successful backup:

SELECT backup_id, database_name, backup_path, lockfree_timestamp FROM information_schema.mv_backup_history WHERE status = 'Success' AND implementation = 'Lockfree' ORDER BY backup_id;

Note: information_schema.MV_BACKUP_HISTORY is populated only when the BACKUP DATABASE command is run to create a database backup.
