Data Retention

[Glenn9999]

Prompted by another thread. General observations more than anything addressed to the OP of that thread: For what I've seen in data processing shops, data preservation is a common practice - in the shops I've seen (mainframe), it isn't uncommon to keep anywhere from 12-36 generations of the data as backup (depending on how frequent the process). Since this is a good topic, I might go ahead and ask - what is the general practice for data retention at most of the shops you've worked at?

FWIW, the tool we used for handling this was part of the OS assign, and the file group as a whole was called a Generational Data Group (GDG). I happened to think too, it might be an interesting project to rig up a similar facility that would work in Delphi for matters such as this. Might try it sometime

In one of my supported applications for a materials testing facility, where the output is certification iaw ISO 9001:2000, the data retention period is 7 years, unless a particular customer requests it to be longer.

British company law requires all invoices etc. to be retained for 7 years. Mainly so the taxman can come and check it.
I've not really considered computer data being backed up, whether it has to follow the same guidelines. If there's data there that might need scrutiny then I suppose it does.

To clarify, I didn't mean retention as in "backed up", I meant keeping copies of data files and not overwriting them, etc.
