Our cloud backup eats the internet line, how do we manage that?

An unconstrained cloud backup can saturate your upload, killing calls, frustrating users and tempting people to disable backup. Throttling, scheduling and tier choice fix it.

Try this first

  1. 1Measure upload bandwidth in numbers: speedtest, business hours and after hours. Base throttle on data, not feelings.
  2. 2Veeam, NAKIVO, Acronis and most tools have Network Throttling with day windows: e.g. 50% of upload during work hours, 100% overnight. Set realistic schedules.
  3. 3Run heavy initial or full backups at weekends or overnight. Daytime incrementals are usually small enough to slip past throttle.
  4. 4For heavy volumes consider a 2nd WAN link (4G/5G-bonded modem) purely for backup. Common in production setups.
  5. 5QoS on the router helps too: voice and video over backup. Not every SMB router supports it, check first.
  6. 6Monitor with PRTG, LibreNMS or a Grafana dashboard. Tuning without data is guessing.

When to bring us in

Multiple offices on shared lines or production apps (VoIP, video) suffering despite throttle, get a network engineer for QoS and SD-WAN design. Often the issue is prioritisation, not bandwidth.
