Can database server's transaction-log-based replication help?
MSSQLServer had this since 1995, and I expect Oracle has this too for
a long.

How aggressively is your data updated?

I would prefer the database-server-based solution, not the
RAID-box-based. It will preserve the transaction boundaries at least.

An array based Snapshot integrated with the host OS & applications will also
accomplish this, i.e. quiesce the DB, flush any uncommited writes and issue
the snapshot. A good example of this approach would be W2K03 and SQLServer
along with a VSS aware storage array.
