Re: Stack popped reading that procedure....
The drive units consisted of a fixed drive and a removable drive pack. On Datapoint, we put the indexs on removable and data on fixed. At backup time, shutdown app, remove index pack, install backup pack. Copy fixed data to backup pack. remove backup pack, reinsert index pack and restart app.
If fixed fails, copy from backup pack to new fixed. install index pack, run a reindex script to regen all index files on the removable pack. Start app.
On large systems, there were multiple drive units that were backed up in parallel. Backup/restore times were consistent. Run out of storage, add another drive unit and storage processor. Redistribute data and indexs across all drives as required.
Easy money.
The DG issue is they had data everywhere making backups a lot more complex and time consuming.
