将数据库复制到备用群集

copycluster.ini

; This sample vbr configuration file is configured for the copycluster vbr task.
; Copycluster supports full database copies only, not specific objects.
; 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]
; For each node of the source database, there must be a [Mapping] entry specifying the corresponding hostname of the destination database node.
; !!Mandatory!!  node_name = new_host/ip  (no defaults)
v_exampledb_node0001 = destination_host1.example
v_exampledb_node0002 = destination_host2.example
v_exampledb_node0003 = destination_host3.example
v_exampledb_node0004 = destination_host4.example
; v_exampledb_node0001 = 10.0.90.17
; v_exampledb_node0002 = 10.0.90.18
; v_exampledb_node0003 = 10.0.90.19
; v_exampledb_node0004 = 10.0.90.20

[Database]
; !!Recommended!! If you have more than one database defined on this Vertica cluster, use this parameter to specify which database to copy.
; 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

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

[Misc]
; !!Recommended!! Snapshot name.
; SnapshotName is used for monitoring and troubleshooting.
; Valid characters: a-z A-Z 0-9 - _
; snapshotName = backup_snapshot

; 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

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

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

; Total bandwidth limit for all copycluster 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 maximum number of restore TCP rsync connection threads per node.
; Results vary depending on environment, but values between 2 and 16 are sometimes quite helpful.
; concurrency_restore = 1

; The maximum number of delete TCP rsync connection threads per node.
; Results vary depending on environment, but values between 2 and 16 are sometimes quite helpful.
; 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
