Hi!

Check that remote path exists. You can get error code 12 if you specify a remote path that doesn't exist.

ashu123

where I have to specify that remote path correctly ??

@ashu123 - In the mapping section of the vbr ini file:

Example:

[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

In the example, the backup directory is /home/dbadmin/backups.

If your backup directory does not exist on 103...* , did you run vbr --task int?

init — Creates a new backup directory, or prepares an existing one, for use and creates necessary backup manifests. You must perform this task before the first time you create a backup in a directory.

hello @Jim_Knicely
This is my vbr.ini file

[Misc]
snapshotName = vertica_backup
restorePointLimit = 1
objectRestoreMode = createOrReplace
tempDir = /tmp/vbr
retryCount = 5
retryDelay = 3
passwordFile = pwdFile

[Database]
dbName = database
dbUser = user
dbPromptForPassword = True

[Transmission]
encrypt = False
checksum = False
port_rsync = 50000
serviceAccessUser = asha
total_bwlimit_backup = 0
concurrency_backup = 1
total_bwlimit_restore = 0
concurrency_restore = 1

[Mapping]
v_db_testing_0_node0001 = 103.*.*.*:home/asha/backup/

Again getting same error

ashu123

If I run vbr init command, the following rsync command is being prepared.

/opt/vertica/bin/rsync -s --list-only -d rsync://[103...*]:50000/vbr//home/asha/backup/backup_manifest

Hi!

[Mapping]
v_db_testing_0_node0001 = 103.*.*.*:home/asha/backup/

path incorrect(no slash / in the beginning.), should be

v_db_testing_0_node0001 = 103.*.*.*:/home/asha/backup/
