#Backup/Restore Datastore Bandwidth Throttling

Hello,
I have a 1gbps fiber internet. On the Blue XP, it is setup for UNLIMITED transfer bandwidth. I just did a restore of a VM back to vCenter. I monitored the bandwidth and it averaged between 190 - 300mbps with some spikes between 500-800 but not for very long. The restore took 1.25 hours. If it averaged high throughput the restore could have faster. Not a router issue I have a Fortigate 500e and no throttling enabled.
Is there something I need to do to get more consistently high bandwidth usage?

Dumb question but what is it being restored from?

Not neccessarily dumb. I should have included that. Blue XP Instance is running in AWS. S3Buckets

If it's an ONTAP system there could be other things, or there could be bandwidth delay product.

When dealing with SM-C / BlueXP Cloud Backup and Restore, there are some "usual" non-network-related reasons for restore t/put. Namely,

  • file size. This is enhanced in recent releases but even so, smaller files may result in lower restore throughput than larger files.
  • fragmentation. This is "how data is arranged in the object-store" and refers to situations when the backup file data is spread across many more objects than it may have originally due to how the data is changed.
