What happens by default if the journal engine service is installed and running when the incremental command is used for a backup?
A . It updates the journal database with current data after a successful backup.
B. It performs a journal-based backup on file systems that are being monitored by the journal engine service.
C. It backs up the file journal on an incremental basis.
D. It monitors the incremental backup process and collects all data that is eligible for the next journal-based full backup.

Answer: B

Explanation:

The journal engine service monitors changes to specified files and directories and records information about the changes in a journal database. When a backup is performed on a file system that is being monitored by the journal engine service, IBM Spectrum Protect uses the information in the journal database to perform a journal-based backup. This allows IBM Spectrum Protect to quickly identify and back up only the files that have changed since the last backup, reducing the amount of data that needs to be backed up and speeding up the backup process.

According to IBM Spectrum Protect V8.1.9 documentation1, journal-based backup is an alternate method of backup that uses a change journal maintained by the IBM Spectrum Protect journal service process. To support journal-based backup, you must configure the journal engine service using the dsmcutil command or the client GUI setup wizard.

The incremental command backs up all new or changed data in the locations that you specify, unless you exclude them from backup services2. If the journal engine service is

installed and running when the incremental command is used for a backup, it performs a journal-based backup on file systems that are being monitored by the journal engine service1.
