Environment
With this environment: Is the only option to 'efficiently' backup Lotus Domino servers (emails and databases) to use a NBU Client and the NBU Notes DB Agent inside the Guest OS? and perform Full and Incrementals.
Reason for my question is I have tried the NetBackup for VMware backup method with Mapped Full VM, BLIB option, Exclude unused and deleted blocks, Full and Incremental schedules, ALL_LOCAL_DRIVES. The resultant backup size between Full and Incrementals is not much different. The total file numbers backed up IS different.
Example (data taken from the columns in Activity Monitor):
Full Backup of Domino Server = 301GB (Files: 60045)
next Incremental = 274GB (Files: 1450)
My initial understanding is that every day databases and email .nsf files seem to get changed, at least their timestamp on the filesystem is updated, and I presume that Indexing and Compression happens on each of these files regularly so the VMware Method is just not fit for the job.
Have not found a definitive answer to this or a decent paper to discuss protection for Lotus Domino servers in the Virtual environment.
Similar question posed on IBM's site, but no comments.

On the VMware backup host, the client properties:
Perform incrementals based on archive bit is unchecked.

Did you disable "Perform incrementals based on archive bit" ?

It sounds like you have answered your own question. The nature of BLIB and how the Lotus Notes server is working makes it not a prime candidate for incremental backups on a VMware level. So I may run a Full VMware Backup every week or every month. And use the Agent base backups to cover the fulls and incrementals in between.
