Hi,

We love Kafka but I would pretty strongly disagree with that statement. Backups 
are not really about recovering from local failures and lots of systems that 
are resilient and redundant have backups as well (e.g. CockroachDB). Uses of 
backups in a system like Kafka would include:

1) Recovering from application errors that have damaged the record and history 
(e.g. an accidental day of streaming incorrect data into Kafka)
2) Recovering from accidentally applied admin errors (e.g. deleting a topic)
3) Recovering from DC level failures (yes MirrorMaker works, but is not always 
appropriate)
4) Transferring point in time images to other systems for analysis (e.g. 
production data to development for analysis of issues)

So for us backups would be a fantastic addition to Kafka

Thanks,
Ben
