Here is my lab environment test result on Direct Restore to GCP.
Note: Does not represent the real scenario. Recommend testing on your environment to get the exact result.
The below sharing is just for test purposes
Bandwidth used:
- Download: 800Mbps
- Upload: 200 Mbps
a) Restore from on-prem backup target to GCP
Using worker e2-micro
Using worker c2d-highcpu-2
b) Restore from GCP object storage to GCP
Using worker c2d-highcpu-2
Conclusion:
- More faster when backup data resides on GCP object storage
- Changing to the higher spec of worker does not improve the restore speed
