I'm really getting mad. This make sense for the behaviour (the first
VirtualFull worked because read full and incremental for the same pool) but
still the docs confuse me.
https://www.bacula.org/9.4.x-manuals/en/main/Migration_Copy.html
No. Not because they were in the same pool, but rather because the
volumes were all loadable and readable by the same device.
OK.
readable by that particular device. Hence, all volumes must have the
same Media Type, because they must all be read by the same read device.
OK.
In a nutshell, you must have multiple devices and you must ensure that
one device reads all of the existing volumes and another different
device writes the new virtual full volumes. This is why it is not
possible to do virtual fulls or migration with only a single tape drive.
OK. Try to keep it simple.
Storage daemon have two devices, that differ only for the name:
Device {
Name = FileStorage
Media Type = File
LabelMedia = yes;
Random Access = Yes;
AutomaticMount = yes;
RemovableMedia = no;
AlwaysOpen = no;
Maximum Concurrent Jobs = 10
Volume Poll Interval = 3600
Archive Device = /rpool-backup/bacula
}
Device {
Name = VirtualFileStorage
Media Type = File
LabelMedia = yes;
Random Access = Yes;
AutomaticMount = yes;
RemovableMedia = no;
AlwaysOpen = no;
Maximum Concurrent Jobs = 10
Volume Poll Interval = 3600
Archive Device = /rpool-backup/bacula
}
director side i've clearly defined two storages:
Storage {
Name = SVPVE3File
Address = svpve3.sv.lnf.it
SDPort = 9103
Password = "ClearlyNotThis."
Maximum Concurrent Jobs = 25
Maximum Concurrent Read Jobs = 5
Device = FileStorage
Media Type = File
}
Storage {
Name = SVPVE3VirtualFile
Address = svpve3.sv.lnf.it
SDPort = 9103
Password = "ClearlyNotThis."
Maximum Concurrent Jobs = 25
Maximum Concurrent Read Jobs = 5
Device = VirtualFileStorage
Media Type = File
}
Then on client i've defined a single pool:
Pool {
Name = FVG-SV-ObitoFilePoolIncremental
Pool Type = Backup
Storage = SVPVE3File
Maximum Volume Jobs = 6
Volume Use Duration = 1 week
Recycle = yes
AutoPrune = yes
Action On Purge = Truncate
Volume Retention = 20 days
}
and a single job:
Job {
Name = FVG-SV-Obito
JobDefs = DefaultJob
Storage = SVPVE3File
Pool = FVG-SV-ObitoFilePoolIncremental
Messages = StandardClient
NextPool = FVG-SV-ObitoFilePoolIncremental
Accurate = Yes
Backups To Keep = 2
DeleteConsolidatedJobs = yes
Schedule = VirtualWeeklyObito
Reschedule On Error = yes
Reschedule Interval = 30 minutes
Reschedule Times = 8
Max Run Sched Time = 8 hours
Client = fvg-sv-obito-fd
FileSet = ObitoTestStd
Write Bootstrap = "/var/lib/bacula/FVG-SV-Obito.bsr"
}
The NextPool needs to be specified in the
FVG-SV-ObitoFilePoolIncremental pool resource, not in the job resource.
In the Copy/Migration/VirtualFull discussing the applicable Pool
resource directives for these job types, it states under Important
Migration Considerations that::
The Next Pool = ... directive must be defined in the *Pool* referenced
in the Migration Job to define the Pool into which the data will be
migrated.
Other than that, you are specifically telling the job to run on a single
Storage resource. That will not work, unless the single Storage resource
is an autochanger with multiple devices. You need to somehow ensure that
Bacula can select a different device for writing the new virtual full
job. If you are using version 13.x, then you can define the job's
Storage directive as a list of Storage resources to select from. For
example:
Job {
Name = FVG-SV-Obito
Storage = SVPVE3File,SVPVE3VirtualFile
...
}
I believe that a virtual full job will only select a single read device,
so the above may be all that is needed.
Otherwise, you can use a virtual disk autochanger.
If i run manually:
run job=FVG-SV-Obito
work as expected, eg run an incremental job. If i try to run:
run job=FVG-SV-Obito level=VirtualFull storage=SVPVE3VirtualFile
The job run, seems correctly:
*run job=FVG-SV-Obito level=VirtualFull storage=SVPVE3VirtualFile
Using Catalog "BaculaLNF"
Run Backup job
JobName: FVG-SV-Obito
Level: VirtualFull
Client: fvg-sv-obito-fd
FileSet: ObitoTestStd
Pool: FVG-SV-ObitoFilePoolIncremental (From Job resource)
NextPool: FVG-SV-ObitoFilePoolIncremental (From Job resource)
Storage: SVPVE3VirtualFile (From Command input)
When: 2023-09-29 11:30:36
Priority: 10
OK to run? (yes/mod/no): yes
Job queued. JobId=11718
in log i initially catch:
29-Sep 11:30 lnfbacula-dir JobId 11718: Start Virtual Backup JobId 11718,
Job=FVG-SV-Obito.2023-09-29_11.30.48_26

29-Sep 11:30 lnfbacula-dir JobId 11718: Found 47215 files to consolidate into
Virtual Full.
29-Sep 11:30 lnfbacula-dir JobId 11718: Using Device "FileStorage" to read.
then, after some time:
29-Sep 11:44 svpve3-sd JobId 11718: JobId=11718, Job
FVG-SV-Obito.2023-09-29_11.30.48_26 waiting to reserve a device.
So, it is still waiting to reserve a device... i suppose for writing...
Pool/media situation is now:
*list media pool=FVG-SV-ObitoFilePoolIncremental
Using Catalog "BaculaLNF"

And because some of the jobs are in current volume 'Obito_Inc_0004', and
still 've not clear if a VirtualFull can read and write (append) to the same
volume i've also tried to label a new one. Nothing changed.
What i'm doing wrong?! Thanks...
