Leaving a backup uncapped will cause it to utilise all of the available bandwidth, which for businesses with limited broadband speeds will cause major problems. As a managed service provider (MSP) you need to take into account that not all customers have the luxury of fast broadband, so it’s likely to take much longer. This is quick but even if it’s started over the weekend the upload will run over into Monday morning when everyone comes into the office. We can use a file transfer calculator like the Cloud Calculator and enter the available upload speed and the size of the initial backup and it will give us the estimated time to upload the backup.įor example, uploading an initial backup size of 500GB with an upload speed of 17Mbps will take an estimated 2 days 22 hours and 10 minutes. In reality it’s going to me much less but without any tools it’s always beneficial to assume the worst.įrom here, we then take the initial size of the backup to be transferred offsite and we can calculate the time required to upload it. Without any estimation tools we need to assume the worst case scenario, which is that all of our data is already compressed so the initial backup size will be the size of the backup selection. Estimated backup transfer size (seed) and calculate time to upload So we can use this average upload speed to calculate how long our initial and delta backup data is going to take to transfer offsite.

Since we’re uploading data we don’t need to concern ourselves with the download.

On our own network each test reported upload speeds of 17Mbps. Running the test on your network at various points during the day will give you an idea of usage and available bandwidth. If you have a router with a bandwidth monitoring feature, you should use that to get more accurate results where possible. There are plenty of speed test sites available, but I use Just remember this only gives you a snap shot of what speeds are attainable at that point in time, but it can give you some initial figures to work with. Calculating available bandwidth during working hoursĪ quick way to gauge your available bandwidth is to run a speed test.

If you’re already pushing the limits of your internet connection, then configuring an offsite backup solution could cause an upload bottleneck resulting in lower download speeds. Unless you have an abundance of upload bandwidth available then you should definitely have a limitation in place.

In the case of offsite backups this will usually be during the first initial backup, which depending on the speed of the connection, could be anything from a few minutes to several days. Should I use it?Īny system that will attempt to utilise all available bandwidth will likely cause issues at some point. It’s important to remember that the limitation to bandwidth may not just be the internet connection, but could also be the device’s link speed, for example if a device (laptop or pc) connects over wireless. Without bandwidth throttling, your backup system will attempt to use all of the available bandwidth the network or device being backed up is capable of supplying – this will obviously slow down critical business systems if during working hours. Typically, this will be during normal working hours when the network is under heaviest use. Bandwidth throttling is an important tool for backup as it enables you to limit the amount of available bandwidth your backup system will use during a set period of time.
