I just start with some quick specs of my environment:
- Forward Incremental Forever from Mo-Fr (with 20 restore points) - Tape export of the week for the backups created during the week - 80 TB Full backups - 25 TB Incremental Backups
The easiest way to configure the Tape export from my point is creating one single job and add all backup repositories. Choose the Virtual Full day on Monday.
The problem that occurs now on my site: This single job starts with creating the virtual Fulls for ALL my backup jobs before it starts to write them to tape. So it takes over 12 hours before the "real" tape export starts. As our current bottleneck is the speed of the tape drives these 12 hours are hitting the time window of the weekend to export the data to tape.
It would be great if the following feature could be added: Parallel creation of Virtual Full and Write to Tape (not for a unique Backup Job) - Create Virtual Full of the first Backup Job - While the second virtual Full is created already start to write the first Backup Job to tape. So you only wait 30 minutes (or less) until the write to tape starts.
I know I could created several Tape jobs to achieve this behavior but the configuration is much complexer. Or I can use a File to Tape job (but this will write around 15 TB not needed backup files to tape).
