[Bacula-users] Virtual Backups

Hi all,
i'm trying to configure a bacula 5.0.2 to do virtual backups.
I'm able to do the first virtual backup with success, but after
that, i'm unable to do a new one.
This is the error message that i'm receiving in the second virtualfull:
07-Jan 15:07 b01-dir JobId 1335: Using Device
"myclient-FileStorageVirtualFull"
07-Jan 15:07 b01-sd JobId 1335: acquire.c:117 Changing read device. Want
Media Type="myclient-FileVirtualFull" have="myclient-File"
device="myclient-FileStorage" (/var/bacula/backups/clients/myclient)
I'm using a different Pool for every kind of backups:
Job {
...
Pool = myclient-FullPool
Full Backup Pool = myclient-FullPool
Incremental Backup Pool = myclient-IncrementalPool
Differential Backup Pool = myclient-DifferentialPool
Storage = myclient-Storage
...
}
Pool {
...
Name = "myclient-VirtualFullPool"
Label Format = "${Year}${Month:p/2/0/r}${Day:p/2/0/r}_
${Hour:p/2/0/r}${Minute:p/2/0/r}-myclient-virtualfull"
Pool Type = Backup
Maximum Volume Jobs = 1
Storage = myclient-StorageVirtualFull
NextPool = myclient-FullPool
...
}
Pool {
...
Name = myclient-FullPool
Label Format = "${Year}${Month:p/2/0/r}${Day:p/2/0/r}_
${Hour:p/2/0/r}${Minute:p/2/0/r}-myclient-full"
Pool Type = Backup
Maximum Volume Jobs = 1
...
}
Obviously I also have a pool for Incremental and Differential.
This is the storage daemon configuration:
Device {
Name = myclient-FileStorage
Device Type = File;
Media Type = myclient-File
Archive Device = "/var/bacula/backups/clients/myclient"
LabelMedia = yes;
Random Access = yes;
AutomaticMount = yes;
Requires Mount=no;
RemovableMedia = no;
AlwaysOpen = no;
}
Device {
Name = myclient-FileStorageVirtualFull
Device Type = File;
Media Type = myclient-FileVirtualFull
Archive Device = /var/bacula/backups/clients/myclient
LabelMedia = yes;
Random Access = yes;
AutomaticMount = yes;
Requires Mount=no;
RemovableMedia = no;
AlwaysOpen = no;
}
What I understood from documentation is that Bacula will read
Full,Differential and Incremental volumes from the Pool specified
in "Pool" directive from the Job resource and then it will write
the VirtualFull backup to the NextPool resource of the original Pool.
This will work for the first time, but the second time, it tries
to read the VirtualFull from the original Pool regardless the
real pool and storage specified with "NextPool"
Any hints?
