Backup/restore to cloud storage
backup_restore_cloud_storage.ini
You can backup and restore Enterprise Mode and Eon Mode databases to a cloud storage location. You must back up Eon Mode databases to a supported cloud storage location. Configuration settings in the [CloudStorage] section are identical for both Enterprise Mode and Eon Mode.
There are one-time configurations that you must complete before your first backup to a new cloud storage location. See Additional considerations for cloud storage for more information.
Backups to on-premises cloud storage destinations require additional configuration for both Enterprise Mode and Eon databases. For details about the additional requirements, see Configuring cloud storage backups.
To restore, use the same configuration file that you used to create the backup. To restore selected objects rather than the entire database, specify the objects to restore on the vbr
command line using --restore-objects
.
; This sample vbr configuration file shows backup to Cloud Storage e.g AWS S3, GCS, HDFS or on-premises (e.g. Pure Storage)
; This can be used for Vertica databases in Enterprise or Eon mode.
; Section headings are enclosed by square brackets.
; Comments have leading semicolons (;) or pound signs (#).
; Option and values are separated by an equal sign.
; Only arguments marked as '!!Mandatory!!' must be specified explicitly.
; All commented parameters are set to their default value.

[CloudStorage]
; This section replaces the [Mapping] section and is required to back up to cloud storage.
; !!Mandatory!! Backup location on Cloud or HDFS (no default).

; cloud_storage_backup_path = webhdfs://backup_nameservice/database_backup_path/
; cloud_storage_backup_path = azb://backup_account/backup_container/
; !!Mandatory!! directory used to manage locking during a backup (no default). If the directory is mounted on the initiator host, you
; should use "[]" instead of the local host name. The file system must support POSIX fcntl flock.

[Misc]
; !!Recommended!! Snapshot name
; Backups with the same snapshotName form a time sequence limited by restorePointLimit.
; SnapshotName is used for naming archives in the backup directory, and for monitoring and troubleshooting.
; Valid values: a-z A-Z 0-9 - _
; snapshotName = backup_snapshot
; Specifies how Vertica handles objects of the same name when restoring schema or table backups.
; objectRestoreMode = createOrReplace
; Specifies which tables and/or schemas to copy. For tables, the containing schema defaults to public.
; Note: 'objects' is incompatible with 'includeObjects' and 'excludeObjects'.
; (no default)
; objects = mytable, myschema, myothertable
; Specifies the set of objects to backup/restore; wildcards may be used.
; Note: 'includeObjects' is incompatible with 'objects'.
; includeObjects = public.mytable, customer*, s?
; Subtracts from the set of objects to backup/restore; wildcards may be used
; Note: 'excludeObjects' is incompatible with 'objects'.
; excludeObjects = public.*temp, etl.phase?
[Database]
; !!Recommended!! If you have more than one database defined on this Vertica cluster, use this parameter to specify which database to backup/restore.
; dbName = current_database
; If this parameter is True, vbr prompts the user for the database password every time.
; If False, specify the location of password config file in 'passwordFile' parameter in [Misc] section.
; dbPromptForPassword = True
; If true, vbr attempts to connect to the database using a local connection.
; dbUseLocalConnection = False
