Hello,
About the Synthetic Backup Feature
The synthetic backup feature eliminates the necessity for performing multiple full
backups for supported remote resources. And, because the synthetic backups are run on
the Backup Exec media server without accessing the remote resource, you can schedule
the synthetic backup to be created outside of the time critical backup window, thus
reducing the overall backup window and the associated network bandwidth
requirements.
To start the synthetic backup process, a one-time baseline job is run. The first backup that is
run that is associated with the synthetic backup is considered the baseline job, and always
backs up all of the files, even it is an incremental backup. The baseline job can be either a
full or incremental backup, and must include the option Collect additional information
to detect moved, renamed, or newly installed files.
After the baseline job completes, only incremental backups are necessary. The synthetic
backup itself is created when you schedule it, but only after the baseline job and at least
one incremental backup has completed. The synthetic backup combines data from the
baseline job and from the subsequent incremental backups to form a synthesized full backup of the selected resources.
Please update us on this issue.
