I am the owner of a Synology NAS at home. As I’m cautious about the data of the computers we use, everything is backed up to this NAS using Synology Active Backup for Business.
To extend the protection further, I decided to store these backups in an object storage of my preferred cloud service provider.
So I configured Synology Hyperbakup to backup the Active Backup for Business vault to one of my Scaleway Object Storage buckets.
The first backup occurred on a Sunday night …
Monday morning (it was holiday), my son came to me asking :
- Dad?
- Yes?
- Is there an issue with internet because my ping constantly goes wacko … and I can’t play Counter Strike …
…
I of course immediately suspected the new backup and got confirmation of my suspicions by having a look at the network monitor of my NAS and seeing 2.6 MB/s of upload.
No problem, I will limit the bandwith of Hyperbackup to something less generous and everyone will be happy … except that there is no bandwith limitation settings in Hyperbackup!
After a quick search on Synology’s forums, I found the solution below.
- Logon to DSM GUI of your NAS running Hyper Backup.
- Open Control Panel - Network.
- Switch to the Traffic Control tab and choose Create a new rule.
- Check Custom Rule, click Custom button.
- Select Destination Port as Type. This is important as by default it’s Source Port that is selected.
- Enter Port 443, and click ok. The backup to Scaleway object storage does use HTTPS connections.
- Enter minimum / maximum bandwidth (128/512 KByte/s in my case).
- Click Save on the Traffic Control tab.
If you have followed the steps carefully, you should immediately see the upload bandwith going down to the maximum limit you specified … and making your son happy again while you keep your data protected.
Take care.
