How CA ARCserve Backup Engines Work

The CA ARCserve Backup Server consists of three functional engines:

• The Job Engine--This engine processes your jobs at their designated date and time. It scans the job queue for a job that is ready to run, then sends it to the appropriate handler.
• The Tape Engine--This engine communicates with, and controls, your storage devices. The Tape Engine selects the device needed for a job.
• The Database Engine--This engine maintains a history of:
  • Information about jobs processed by CA ARCserve Backup, such as the job type, the final result, the start and end time, submitter, and description.
  • Media used by CA ARCserve Backup, such as its type, its name, the date it was first formatted, its expiration date, and the sessions on it.
  • Files, directories, drives, and machines that CA ARCserve Backup has backed up or copied.

You can control these CA ARCserve Backup engines in the Server Admin. To view information about an individual engine, open the Server Admin from the Quick Start menu in the Navigation Bar on the Home Page. From the ARCserve domain directory tree, select the primary server, member server, or stand-alone where you want to obtain engine status information.

Important! To manage and configure CA ARCserve Backup engines, you must be logged in to CA ARCserve Backup with the caroot password or a CA ARCserve Backup Administrator account.

• Job Engine--Displays information about the jobs submitted, such as the total number of jobs and the number of ACTIVE, READY, HOLD, and DONE jobs. It also shows the queues, which ones are being scanned, and the scanning interval.
• Tape Engine--Displays information about jobs using the Tape Engine, such as the type of job, and who submitted it. It also displays information on media groups.
• Database Engine--Displays pruning information related to the ARCserve database.
