We use the notes agent, and write about 380GB of data to tape, coming
from two servers.  The mailboxes are split by alphabet.  Average
throughput to tape is about 8 to 10 MB/sec from each client, and we do a
full backup every night.  We keep the weekend fulls at a different
retention than the weekdays, and backing up this much data makes a
recovery very simple.  I have reviewed the incremental notes backup, and
it appears to only get the transaction logs. We have not tested a
restore from this type of backup, so I don't know how well it works.  I
think we might just be lucky so far that we've never needed to roll a
data file forward from logs.  Usually we're restoring the entire .nsf
file and letting users attach to the current and previous one to manage
the differences.

Along with the full .nsf backups for mail, we also get the transaction
logs.  I don't think I've ever needed to use them.
