As part of testing Restorify, we’ve been using it to back-up our production Small Business Server 2003 machine. By the way, I blogged previously about the procedure for virtualizing that SBS machine; this has recently become easier.

The VHD of the SBS machine is 40 GB. This transfer data is based on a two-day window. In other words, we created a backup then created another one two days later (it would be better to do so every night, for example, in production, but we’re trying different scenarios to see how the thing scales).

The delta after two days was 300 MB, which is less than 1%.

What was the workload, exactly? In summary, the server hosts about 5 GB of LOB data under active usage. It is not running Exchange.

Edit: we’re much more efficient now; I updated the numbers above.
