外部完整备份/还原

backup_restore_full_external.ini

外部（分布式）备份将每个数据库节点备份到不同的备份主机。节点映射到 [Mapping] 部分中的主机。

要还原，请使用与创建备份时相同的配置文件。

; This sample vbr configuration file shows full or object backup and restore to a separate remote backup-host for each respective database host.
; Section headings are enclosed by square brackets.
; Comments have leading semicolons (;) or pound signs (#).
; An equal sign separates options and values.
; Specify arguments marked '!!Mandatory!!' explicitly.
; All commented parameters are set to their default value.

; ------------------------------------------- ;
;;; BASIC PARAMETERS ;;;
; ------------------------------------------- ;

[Mapping]
; !!Mandatory!! This section defines what host and directory will store the backup for each node.
; node_name = backup_host:backup_dir
; In this "parallel backup" configuration, each node backs up to a distinct external host.
; To backup all database nodes to a single external host, use that single hostname/IP address in each entry below.
v_exampledb_node0001 = 10.20.100.156:/home/dbadmin/backups
v_exampledb_node0002 = 10.20.100.157:/home/dbadmin/backups
v_exampledb_node0003 = 10.20.100.158:/home/dbadmin/backups
v_exampledb_node0004 = 10.20.100.159:/home/dbadmin/backups

[Misc]
; !!Recommended!! Snapshot name.  Object and full backups should always have different snapshot names.
; 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 characters: a-z A-Z 0-9 - _
; snapshotName = backup_snapshot

[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

; ------------------------------------------- ;
;;; ADVANCED PARAMETERS ;;;
; ------------------------------------------- ;

[Misc]
; The temp directory location on all database hosts.
; The directory must be readable and writeable by the dbadmin, and must implement POSIX style fcntl lockf locking.
; tempDir = /tmp/vbr

; Specifies the number of historical backups to retain in addition to the most recent backup.
; 1 current + n historical backups
; restorePointLimit = 1

; Full path to the password configuration file
; Store this file in directory readable only by the dbadmin
; (no default)
; passwordFile = /path/to/vbr/pw.txt

; When enabled, Vertica confirms that the specified backup locations contain
; sufficient free space and inodes to allow a successful backup. If a backup
; location has insufficient resources, Vertica displays an error message explaining the shortage and
; cancels the backup. If Vertica cannot determine the amount of available space
; or number of inodes in the backupDir, it displays a warning and continues
; with the backup.
; enableFreeSpaceCheck = True

[Transmission]
; Specifies the default port number for the rsync protocol.
; port_rsync = 50000

; Total bandwidth limit for all backup connections in KBPS, 0 for unlimited. Vertica distributes
; this bandwidth evenly among the number of connections set in concurrency_backup.
; total_bwlimit_backup = 0

; The maximum number of backup TCP rsync connection threads per node.
; Optimum settings depend on your particular environment.
; For best performance, experiment with values between 2 and 16.
; concurrency_backup = 1

; The total bandwidth limit for all restore connections in KBPS, 0 for unlimited
; total_bwlimit_restore = 0

; The maximum number of restore TCP rsync connection threads per node.
; Optimum settings depend on your particular environment.
; For best performance, experiment with values between 2 and 16.
; concurrency_restore = 1

; The maximum number of delete TCP rsync connection threads per node.
; Optimum settings depend on your particular environment.
; For best performance, experiment with values between 2 and 16.
; concurrency_delete = 16

[Database]
; Vertica user name for vbr to connect to the database.
; This setting is rarely needed since dbUser is normally identical to the database administrator
; dbUser = current_username
