Hi,
I need to transfer file ~40 GB backup file with maximum speed from office to azure blob
AzCopy /Source:F:\BACKUP\SQL_backup_2018_10_26_23.bak /Dest:https://myblob01.blob.core.windows.net/sqltest/SQL_backup_2018_10_26_23.bak /DestSAS:"?sv=2017-11-09&ss=somevalues"
Finished 1 of total 1 file(s).
[2018/11/02 18:44:29] Transfer summary:
-----------------
Total files transferred: 1
Transfer successfully: 1
Transfer skipped: 0
Transfer failed: 0
Elapsed time: 00.03:41:56
I can see that Average Speed:3.58 MB/s.
source file located in office Canada EST , blob destination US EST
1. does transfer rate depend on subscription type ?
2.Any way to improve transfer rate ?
Thank you
Alex

Best way I've found of speeding up AzCopy is by tuning the number of threads used - parameter "/NC" - have a look at the documentation https://docs.microsoft.com/en-us/azure/storage/common/storage-use-azcopy#azcopy-parameters

I tested "/NC" option on 2 GB file with /NC setting 5,10,25,50,100,250
with /NC 5,10,25 speed was about the same (between 3.00 and 3.6 MB/s)
with /NC 50+ speed goes bellow 2 MB/s
I also tied upload to different regions based on stats from http://www.azurespeed.com/Azure/Upload
changing upload region did not change upload time in my case
