Hello Julio,

Can you please tell me what backup mode you are using in Veeam Agent job settings? Also, what is your Veeam Agent version?

Thank you!

i think many jobs execute simutaly is a problem for veeam, pending jobs at 18 hours
many disk read so slow

Hello Julio.

According to the screenshot you are referring to Backup Copy job and not actual agent backup process, is that correct? May I ask what is the source and target repository for your backup copy jobs and how they are connected? I do see a lot of backup copy jobs running in parallel, so you might simply reach the performance of your target storage (as bottleneck analytics states that target is the bottleneck).

in backup repositories

You can run a quick test - disable other backup copy jobs with the same repository as a target and compare the performance (or run single backup copy with agents when other backup copy jobs are inactive). I believe there should be a way to check the performance during the backup via HPE 3Par console as well.

all backup from retation go to DataDomain
Fibre throughput is good

If I may chime in...

This thing:

Looks pretty much like DD limitation. At this point I'd suggest to contact our support team so they can confirm or disprove that.

Thanks!
