Hi all, I have a setup where I backup some files into a "File" storage (i.e. not on tape). I have set the maximum volume size to something around 2 GB to avoid some problems when transfering them later via FTP, storing them on other file systems etc.
One of the files to be backuped has around 3.5 GB. In all my backups this file (obviously) spans two volumes. The problem: this large file can not be restored. Using the "restore" command in the bacula console results in this: * restore ... Start Restore Job 1und1big-restore.2009-03-18_13.02.08 Using Device "1und1big" Ready to read from volume "1und1big-0146" on device "1und1big" (/var/backup/1und1big). End of Volume at file 0 on device "1und1big" (/var/backup/1und1big), Volume "1und1big-0146" Ready to read from volume "1und1big-0147" on device "1und1big" (/var/backup/1und1big).

This is very likely no hardware defect on my hard disk because this happens with ALL backups I've ever made. I've even tried to use bscan to update the catalog, but this did not change anything - the error messages during "restore" and "bextract" are the same. Any ideas how to restore this file? This is a kind of desaster situation because at the moment I NEED this backup. So of course it would be nice to know how to avoid this problem for future backups. But I would also be lucky about a way how to completely restore this file (I guess all relevant data is available in the backups files, but the restore process does not handle it well). Any help possible?
