Re: [Bacula-users] Migrating jobs between different SDs (servers)
Hi Mariusz ! Welcome to the underrated migrating club ! :) I also tried to migrate between SDs to no avail. I supposed that migration for us bacula users using FILE storage systems would be implemented as well, but alas, it is not. Why did you want to migrate the files ? Something connected to expanding a filesystem ? Because this is a feature of FILE based volumes, that they are not easily extendable (as opposed to tapes) and migration could be a good way to transfer data between old (let's say a 1TB LVM system) and new (4TB netapp) storage systems. Finally, I moved the volumes themselves to the new storage server (10X 400GB SATA disks), and migrated the old server's TCP/IP address to the new server. bacula picked up from there and it eventually worked quite well, except for the Intel 965 motherboard that is not well supported by linux.

The problem is that those who have time to work on features don't have enterprise-scale systems and so don't work on enterprise-scale related features. Those who do have such systems don't have the time (and/or programming ability) to try and write such code. There is nothing stopping you from working on (or paying for someone to work on) the necessary code and then contributing it back into the feature pool. - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
