ndmp_moving_path_notify script (UNIX)
The UNIX scripts are provided as examples only. You must customize the scripts before using them. For example, the -ne value in the first if statement must be modified to reflect the number of passed parameters. For the ndmp_moving_path_notify script, the -ne value must be set to 7.
To use this script, create a script similar to
on the server, and copy it to
on the UNIX NetBackup for NDMP server. Then, modify the script and ensure that you have permission to run it.
On UNIX media servers, the ndmp_moving_path_notify script runs after the backup process sends data to NetBackup.
Before you use this script, make sure you can run it using other on the media server. Run chmod 755 script_name, where script_name is the name of the script.
If the /usr/openv/netbackup/bin/ndmp_moving_path_notify script exists, it runs in the foreground. The bptm process that is on the NetBackup for NDMP server waits for it to complete before continuing. Any commands in the script that do not end with an & character run serially.
The server expects the client to respond with a continue message within the period of time that the NetBackup CLIENT_READ_TIMEOUT option on the server specifies.
The default for CLIENT_READ_TIMEOUT is 300 seconds. If the script needs more than 300 seconds, increase the value to allow more time.
NetBackup passes the following parameters to the script:
Table: Script parameters for ndmp_moving_path_notify (UNIX)
Specifies the name of the NDMP host.
Specifies the policy name from the NetBackup catalog.
Specifies the schedule name from the NetBackup catalog.
Specifies one of the following:
INCR (differential incremental)
CINC (cumulative incremental)
Specifies the NetBackup status code for the operation.
Specifies the path being backed up.

To create an ndmp_moving_path_notify script for a specific policy or policy and schedule combination, create script files with a .policyname or .policyname.schedulename suffix. In the following two examples of script names, the policy is named production and the schedule is named fulls:
The first script affects all scheduled backups in the policy that is named production. The second script affects scheduled backups in the policy that is named production only when the schedule is named fulls.
For a given backup, NetBackup uses only one ndmp_moving_path_notify script and that is the one with the most specific name. For example, if there are both ndmp_moving_path_notify.production and ndmp_moving_path_notify.production.fulls scripts, NetBackup uses only ndmp_moving_path_notify.production.fulls.
The ndmp_moving_path_notify script can use the following environment variables:
BACKUPID UNIXBACKUPTIME BACKUPTIME
The NetBackup bptm process creates these variables. The following are examples of the strings that are available to the script for use in recording information about a backup:
BACKUPID=freddie_0857340526 UNIXBACKUPTIME=0857340526 BACKUPTIME=Sun Mar 2 16:08:46 1997
