Sizing space for replication

[ashman70]

How do you determine how much space you will need for replication?

I have a VM that is 255GB and is currently backed up once a day, the amount transferred varies from day to day, but is usually between 1.5 and 3.5GB. If I want to setup replication for this VM that will happen every 15 minutes, how much disk space would I need to allocate?

It depends on amount of changes occurred within 15 minute interval. I recommend you running several tests and seeing how much data will be transferred during the newly specified period (15 min). Thanks.

Let me chime in to this - you may want to consider using Veeam ONE predefined report (VM change rate estimation) that estimates the amount of changes for all VMs you want to replicate/backup. This will give you an idea on what bandwidth and what storage will be required for these VMs.
