Home – Blog – Synology Upload Speed Limit
The Synology NAS has a particularly great feature, namely encrypted backup in the cloud via Hyper Backup. After I had sworn off unencrypted cloud services (including Dropbox), the combination of encrypted backup and the cloud flat rate of Amazon Prime was so attractive. Unfortunately, the backup unfortunately ate up the entire bandwidth of the upload volume, 12 MBit. This speeds up the backup, but also slows down the Internet in the home network.
The “Traffic Control” in Synology DSM was supposed to remedy this, but this is where the problems started. First of all, you can’t choose Hyper Backup as an application whose bandwidth is to be restricted. If the need is great, then of course you can also select all ports and allocate less bandwidth to them, for example 2,000 KB/s. And this is exactly where the mistake lies.
First of all, the port 443 of the destination folder must be selected, this is the port used by Amazon (and probably other services as well). And then comes the biggest misunderstanding, because 2,048 KB/s is not 2 MB/s, but something else that I haven’t understood so far. Because if I select 500 KB/s, then the NAS uses 5 MB/s.
How can that be? Maybe KB/s don’t mean kilobytes/s at Synology, but kilobits/s? But that wouldn’t be 5MBit/s, which Google Wifi now shows in the app.
