Database Copy to an Alternate Cluster (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!!

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 ; How many times to retry operations if an error occurs. ; retryCount = 2 ; Specifies the number of seconds to wait between retry attempts, if a failure occurs. ; retryDelay = 1 ; 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 ; The maximum ; acceptable difference, in seconds, between the current epoch and the backup epoch. ; If the time between the current epoch and the backup epoch exceeds the value ; specified in this parameter, Vertica displays an error message. ; SnapshotEpochLagFailureThreshold = 3600 [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.
