Firstly, thank you very much to all involved in the development of Duplicati.
I would like to report, what is perhaps, a bug?:
I am backing up to an offsite SFTP server. I have not tested this issue for local backups.
If I set a throttle-upload value for a backup job, this also effects restores from this backup job.
For example, if I set a throttle-upload value of 37KB/s, this results in a restore of a 15.5KB file taking over 20 minutes (I think it was about 23 or 24 minutes).
If I remove the throttle-upload from the backup job, the restore takes just 3 minutes (approximately).
I have done the calculations for my ADSL speed (upload upto 1Mbps, download upto 15-16Mbps) and this roughly corresponds with the restoration timings, therefore, I have confirmed that the throttle-upload value is indeed effecting the restore operation.
Presumably, to re-create this issue for yourself:
Create a backup job with a throttle-upload value set - Destination offsite.
Make a backup
Go to restore and choose your backup job as the restore from option.
The restore should be slower with the throttle-upload value set.
My way of thinking is that the throttle-upload value should not effects restores. Is my thinking wrong (in which case, this should be a feature request to this effect) or is it a bug?
Thank you in advance.
