Here is a summary of my little survey.  Thank you to all who helped out.
There are stories behind many of these numbers which are hard to put in
a summary chart.  For example, many will raise and lower their migration
and reclamation thresholds manually (or scheduled with Version 2).
A few are performing manual reclamations with MOVE DATA.  Many have
multiple disk storage pools (I just lumped the numbers together).
The OS/2 server customer also has optical in the storage hierarchy.
Anyway, here is the summary that I promised.  Thank you for your help!

Original questions:

ADSM Server Platform:
Approximate amount of data backed up daily:
Amount of data currently in your storage pools:
DB size:
mirroring DB?
Log size:
mirroring Log?
BUFPOOLSIZE:
LOGPOOLSIZE:
TXNGROUPMAX: 256
How often do you run expiration?
Using collocation?
DISK storagepool size:
migration thresholds:

For Version 2 ADSM servers:

logmode NORMAL or ROLLFORWARD?
If ROLLFORWARD, how much did you increase your log?
How long (wall clock) does full BACKUP DB take?
How long (wall clock) does incremental BACKUP DB take?
If applicable, how long (wall clock) did a RESTORE DB take?
MOVEBATCHSIZE:
MOVESIZETHRESH:

For those using BACKUP STGPOOL:

How long (wall clock) does an incremental BACKUP STGPOOL take?
How many processes are used for the backup?
