        Well to date Oracle is keeping their word on backwards compatibility. I know that exports taken in V6.0.36 will successfully import into, but how long that will remain true is anyone's guess. There are a number of vendors who provide long term archival of data via their own proprietary ways and guarantee data retrieval back at least 10 years. Take a look at as an example. A simple Google search for "Oracle data archiving" gets quite a bit back. Come to think of it, I think our good friend Quest has a product too.

Hello fellowship of the Oracle,

due to not so recent changes in
European and German law, many companies, particularly in the financial sector, have the need to archive critical data over a long period, like 6 to 10 years.
BUT - simply using RMan or Export doesn't always suit the requirement to be able to restore data after several years. Just
think about an RMan Backup of a 9i DB that you need to restore in 10 years - we're probably at Oracle 16 or whatever, then and you probably won't be able to restore your old data to this new version. Keeping a copy of the old Oracle binaries is not the best option, either; maybe you won't have the appropriate OS version or hardware handy, then.

So I'd like
to ask the community what kind of solutions you recommend to your customers / managers, when they ask you: "How can we retrieve our data after 10 years if there is a tax audit?"

I've heard,
but haven't found a reliable pointer yet, that Oracle will support backward compatibility of the export dump format throughout the next versions. In this case, a regular snapshot of data by exporting it might be an idea. What are your thoughts on that?

Best regards from
