Hello – We are deploying a new backup system (Rubrik) and I’m being told that it will be faster for our VMware environment since it does an initial full backup and then everything afterwards are incremental/delta backups. What I’d like to know is if there is such a thing as a “delta” or “incremental” snapshot in VMware? My understanding is that, even if the backup is an incremental, the snapshot that the backup tool is initiating with VMware is of the full disk. In fact, I don’t know how VMware itself would even know what the “delta” information in the disk would be at the time the snapshot is initiated. So my assumption is that VMware will do the same thing when it creates the snapshot regardless of whether the backup tool is executing a full or incremental job. Furthermore, I assume that only the backup tool would be able to scan the snapshot (disk) to look for change data that it is interested in. Can anyone offer some insight on this? Thanks!!
