We do something very similiar

- Compact on saturday midnight of all the databaes (DBIID is changed)
- Incremental right after that (actually a full because of the DBIID change
- archive log every hour from 07:00 to 19:00
- incremental every week night

We have 3 domino instances on 1 p690 partition. Total of 350 GB of notes data. 
Our retention is Nolimit, Nolimit, 90, 90. This gives me 2.5 TB of compressed 
data in TSM.

Bill,

You are correct. It also "inactivates" databases
that no longer exist on the Domino server.

If a customer only runs archivelog and selective backups,
the databases that have been "removed" from their
Domino Server will remain active and never expire.

The bigger problem I see with only running weekly SELECTIVE and
hourly ARCHIVELOG (with no INCREMENTAL) is that it will not
pick up situations when the logged databases DBIID has changed.
Once the DBIID changes, you cannot apply
the archive logs to the old backup since Domino
treats databases with a new DBIID as a "different"
database in the logger's eyes.

One very common technique is to run:
   - Weekly SELECTIVE type backups (followed by an INACTIVATELOGS command)
   - Nightly INCREMENTAL type backups
   - Hourly ARCHIVELOG backups

The time frames on the frequency of these vary depending
on Domino server load, capacity, maintenance schedule, etc.

Thanks,

Del
