Re: Informix Parallel Backup Question

Hi all, Thanks for you input and especially Martin for your clarification on this area. Regards Stefan Rob Prop <rpnews@xs4all.nl To: informix-list@iiug.org > cc: Sent by: Subject: Re: Informix Parallel Backup Question owner-informix-li st@iiug.org 08/03/2005 05:28 AM Please respond to Rob Prop Hi Stefan, Informix does support parallel back-ups through onbar, and most storage managers also supports this. However this might need some further explanation. What onbar is doing when using this parallel option is that it will backup several (db)spaces at the same time. (So no two streams on one space). The storage manager will need to decide how to store this data, it could do it on one tape drive or several. Most storage managers do not break up streams, so to allow several drives to be used several spaces need to be backupped in parrallel. Make sure all drives have the possibilitie to mount media belonging to the correct pool. Hope this helps, Rob On Mon, 7 Mar 2005 12:11:17 +1100, Stefan.Gabriel@nylex.com.au wrote: > >Hi All, > >I have a question for you regarding onbar and backups.
