14.1 VIOM Backup Service
The following parameters need to be configured for the backup jobs:
•The Quartz cron expressions which determine when the backup jobs are scheduled (see section "Configuring the job schedule on Windows" on page 339) and "Configuring the job schedule on Linux" on page 342.
•The parameter for the directory where the output files are stored (see sec- tion "Configuring the output directories" on page 343)
Dependencies on the database
On Windows: Both the VIOM Manager and the Backup Service use Windows Authentication to access SQL Server. This means, at the very least, that both services must run under the same Windows account as the SQL Server.
On Linux: The Virtual IO Manager is installed under the root user and with root privileges. The database is accessed via the database user svuser which has already been created by ServerView prior to the
Warning
On Windows: It is a known behaviour of SQL Server that the trans- action log grows unless it is periodically backed up. We therefore strongly recommend that you configure and start the Backup Serv- ice in order to backup at least the transaction log.
14.1.1 Configuring the job schedule on Windows
The jobs and their triggers are defined in the quartz_jobs.xml file in the <installation_path>\VIOM Manager\ directory. Cron triggers may be mod- ified by the user by editing this XML file. The database configuration is taken from the ViomConfig.properties file.
