Why the NetBackup has to take more than 24 hours to backing up the VM?

This is using Veritas NetBackup 8.11. We also using HP Simplivity VMware virtualization. There is a MS Windows VM server having about 700GB in size, in the report, has to take more than 24 hours to complete the snapshot and backup.
However, we checked the VMware web portal and found that the snapshot creation only took few second to complete. The snapshot removal and other jobs completed successfully shown in this VMware portal.
Just confuse why the snapshot and backup image have to take so long to complete. How is the whole process work? Where to look into to solve the problem?

client	Job Type	Job Schedule	Job State	Job Status	Job Start Time	Job End Time	Job Duration (hr)	Job Size (KB)	Job Throughput (kb/sec)
ssinsplunkhf01	Backup	Full_Backup	Done	0	23.05.2021 12:35:53	24.05.2021 00:44:18	12:08:25	733843900	16820
ssinsplunkhf01	Snapshot	-	Done	0	23.05.2021 12:35:42	24.05.2021 00:44:38	12:08:56

Thanks in advance.

I think you are misreading the information and misinterpreting it.

It is a 12 hour transaction.
Step one create a snapshot after recording start of job
Step two, transfer snapshot to backup storage after recording start of job
Step three complete transfer, and Mark transfer complete
Step four deleted snapshot, and Mark task complete.

Note date/time info.

Adding to my earlier comment, why are you starting the backup during the day. Presumably this will be peak utilization time.
See if changing ti to start at 8 pm as an example and have it complete by 8 am the following day Additional benefit you will capture all the data for that day in the backup.

But 16 MB/s is not really a lot..., as far as no other jobs running at the same time...
Would be interesting if the throughput raises if you move the start time to 8:00 pm

Hello There

Job throughput seems a bit low. WIth that throughout the total time of 12 hours to complete the job is expected and there is nothing unusual. I suggest starting the job at a time when nobody works. It should reduce the total time. You can also reconfigure your backups to perform only incremental backups during the week if you haven't done it already.
