[Error] Cannot open backup device, The system cannot find the file specified

Applies to: 

• Liquibase Enterprise (Datical DB)

Conditions:

• Any version of Liquibase Enterprise (Datical DB)
• Using the on_demand backup method

Issue Summary:

When attempting to run Packager, an error will occur about the backup file not being able to be found.

Error Message:

Cannot open backup device '<path_to_backup_file>'. Operating system error 2(The system cannot find the file specified.). 

Root Cause:

During the packager process, a restore from a backup file will occur if any issues are encountered. If the backup method is set to on_demand, a backup file needs to be provided. If the file was either deleted or is no longer on the server, a new backup file will be needed.

Resolution:

You will need to add createDatabaseBackup=true to the deployPackager command in order for a new backup file to get created.

Example:

hammer groovy deployPackager.groovy pipeline=MY_PIPELINE_NAME scm=true createDatabaseBackup=true preview=true
