GitHub user DRDAVIDBANNER added a comment to the discussion: What does 
Snapshots, Backups, and Incremental Snapshots mean in CloudStack

>From an operator/MSP perspective, we treat snapshots and backups as separate

We generally think of a snapshot as a platform-level point-in-time mechanism, 
whereas a backup service needs to cover the wider operational requirements: 
independent retention, policy management, recovery workflows, monitoring, 
reporting and ideally recovery into another location for DR.

At Quadris, we use Sendense for backup and DRaaS across our CloudStack 
environment rather than relying solely on CloudStack snapshots. One of our 
requirements was support for block-storage environments as well as 
CloudStack-aware recovery.

Full disclosure: I am involved with [Sendense](https://sendense.com), but we 
have also been running it operationally in the Quadris cloud for around six 
months. From our perspective, the important question is less about whether 
CloudStack calls an object a “snapshot” or “backup,” and more about whether the 
overall design meets the required RPO, RTO, retention and failure-domain 
requirements.
