tw_backup

The tw_backup utility enables you to create a backup of a BMC Discovery system on a local directory on the appliance, an SSH enabled remote system, or a Windows share. To use the utility, type the following command:

tw_backup [options]

where:

  • options are any of the options described in the following table and the common command line options described in Using-command-line-utilities.

Common password options are described in this table

Common password options are described in this table to make it clear whether the password referred to is for the local or remote system.

Backing up the system when a baseline run is in progress results in critical baseline alerts

Baseline is run periodically by the BMC Discovery system. Should baseline be running when a backup is started critical baseline alerts may be reported. The backup is unaffected by these alerts. The automatic baseline check schedule can be modified using the tw_cron_update. In order to minimize the chance of alerts no new periodic baseline checks are performed during the backup.




User examples

In the following examples, the local username is system and the password is not specified on the command line. The remote SSH username is tideway and the password is password. The remote Windows share is called remshare, the corresponding username is remdom/tideway and the password is password.

The utility prompts for the local password after you enter the command. Type the commands on a single line; line breaks are provided in the examples to make them easier to read.
