[0] Backup windows do not expand as data grows Strong — add full appliances As data grows, full servers are added, each with their own processor, memory, bandwidth and disk. This maintains consistently fast backup performance and a fixed length backup window as data increases. For example, when you grow from 10TB to 20TB (twice the data) the processor, memory, bandwidth and disk all double which means you have twice the resources.
Weak — can only add disk Only disk shelves are added as data grows, This means you start with a shorter backup window, but as data grows, the backup window expands because you are not adding more deduplication processing resources. For example, when your backup grows from 10TB to 20TB, with twice as much data but the same processor and memory, the backup window expands. Eventually, the backup window expands to a point where you must replace the front-end server with a more powerful server.
