Ask HN: What's your experience with using Bareos for backups?

Our use case: We have one main backup server with +50 clients. The size of data for back up is 1TB give or take.

Our current solution is using rsyinc with --delete flag.

We want to implement something similar with Bareos, but it seems this isn't possible without doing periodic full backups. Which we can't afford due to size of the data. Am I missing something obvious here?
