Well, this is where I think you mean there is no support. When dealing with backups, you have to specify a backup device as well as a pool to backup to. A pool could have volumes from many different backup devices, but you can't just specify a pool to pull an available volume from, unless _I_ missed something in the reading. > If there is no workaround, does anyone know how much work it would be to > implement such a feature? At this time I think you manually have to assign each server to a specific storage device. They can all be part of the same pool but thats about it. I'm not sure what it would take to randomize a list of storage devices within a pool. -- Jesse Keating GameHouse -- Systems Engineer --- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf ___ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
RE: [Bacula-users] Storage pool concept
Arne, I'm not sure I understand exactly what you're asking, but to clarify: are you asking if you can setup a pool of physical drives (not pools of volumes/tapes)? If this is the case I believe multiple drive support is (at least partially) working, but as for how to make the director see a given number of drives as a single storage device such that data can be striped -- either sequentially or in parallel -- across the volumes mounted on those drives, I don't think this has been fully implemented yet. I'm sure sometime today Kern or another, more experienced list member could confirm or correct me on this, but I think the answer is "I don't think so." Either way, I think this capability would definitely be a GoodThing(TM) and if it isn't going into 1.38 then I will certainly try to offer what development assistance I can in the next development cycle.

What 1.38 has is the ability for you to specify more than one storage device for a Job. The SD will then select one that is free or corresponds to what the user wants (correct Media Type). However, the Job will be tied to a single storage device. I've added a field in the database that will allow striping of data across devices, but there is no code and I currently don't have it scheduled for implementation. > > I'm sure sometime today Kern or another, more experienced list member could > confirm or correct me on this, but I think the answer is "I don't think > so."

To clarify what i _want_: I want to set up a bunch of backup-servers each with several disk storage devices. I want to be able to set up the backup configuration in a way that i just need to add all those devices in a "pool", and the software cares about which device to use when. So if a device is full or in use another one is used. Features like load-balancing and such are of secondary need for me. A question to the feature in 1.38: What happens if a disk runs full _during_ a backup? Will it be continued on the next SD?
