One more clarification: as of 11.2.0.4, Flashback Data Archive is available in EE AND SE. So you can develop and test on SE, then deploy at scale on EE (maybe with Advanced Compression to "optimize" the FDA history tables)...KJ

And you might be right - but you can use compression, partitioning, and even HCC on Oracle Storage to keep the older FDA-managed history data online in cheaper / denser storage, while transparently keeping the more recent (usually hotter) data on Tier 1 storage etc etc. And, the question is always "What's the value to the business of having online access to the historical data using Flashback Query?" versus the slower more complex approach of restoring the right backup, rolling forward to the right point in time, etc etc...-KJ -- Kevin Jernigan Senior Director Product Management Advanced Compression, Hybrid Columnar Compression (HCC), Database File System (DBFS), SecureFiles, Database Smart Flash Cache, Total Recall, Database Resource Manager (DBRM), Direct NFS Client (dNFS), Continuous Query Notification (CQN), Index Organized Tables (IOT), Information Lifecycle Management (ILM) +1-650-607-0392 (o) +1-415-710-8828 (m) On 2/13/14, 12:50 PM, Freek D'Hooge wrote: But not a history of how a record changed through time. I think the reasoning behind the restore to any point between now and 7 years back is the need to be able to show what a record looked like x time back. If so, maybe flashback data archive and / or auditing could be used to fulfil such a requirement? regards,-- Freek D'HoogeExitas NV Senior Oracle DBA email: freek.dhooge@xxxxxxxxx <mailto:freek.dhooge@xxxxxxxxx> tel +32(03) 443 12 38 http://www.exitas.be <http://www.exitas.be/> On do, 2014-02-13 at 21:36 +0100, Frits Hoogland wrote: Just as a bold statement, and something to think about: isn't your most recent backup a complete backup of all the history contained in your database?

The point about compatibility and cost is very important. Isn't it necessary by law with so many businesses to retain 7 years of data? What do people do in this case? In many places that I know of (including fortune 100 organizations) there is a 7 year retention policy for backup in place but as I had mentioned God only knows what actually happens to those tapes. At times I have asked to test a restore from backup taken long time a go but no one wants to open that can of worms.

For example, an LTO-3 tape written 7 years ago won't be able to be read on an LTO-6 drive -- a very plausible timeline example.
