[Bacula-users] time since last non-virtual backup
Hi, I'm looking to work out a query or script which quotes me the time since the last live backup (ie I don't want to include virtual full backups) for each of our configured jobs. Not all of our backups are scheduled, some are triggered manually, so I need to produce a list of how long it has been in each case. It would be no harm to also check the scheduled ones, just in case there were some configuration error. Has anyone already been over this ground and care to share a query or solution?

[Bacula-users] Waiting on Maximum Storage Jobs

These would always appear to have a backup in the past month, even if it was 6-8 weeks since the incremental last ran, as the VirtualFull would appear there.

Re: [Bacula-users] Volume Rotation Simulation?
This may sound a bit odd, but is there a way to simulate media rotation? For instance, tell the bacula to fast-forward to a point in time and see if volumes get recycled as expected.

[Bacula-users] Firewall traversal
My setup is as follows: Bacula Server (DIR, SD) - Firewall/NAT - Server to be backed up (FD) The FD is accessible from anywhere, but the DIR/SD is not (NAT/FW). When I start the backup, the Director connects to the FD without a problem, but then when the Director tells the FD to connect back to the SD it fails because of the NAT.

Any hints on how to do this?
If you want to exclude dot _files_ (i.e. you don't care about
directories whose name starts with a dot other than .backup), and
assuming you're backing up the whole /home directory, this would be enough:
FileSet
{
Include
{
Options
{
exclude = yes
wildfile = /home/*/.*
}
File = /home
}
}
But this will backup .thunderbird/ with its 800MB
mail cache, yes? That's what I want to avoid (without
having to maintain a list of specific black-listed
files/directories.)
If you also wish to exclude other dot-directories, I would try something
like:
FileSet
{
Include
{
Options
{
wilddir = /home/*/.backup
}
Options
{
exclude = yes
wild = /home/*/.*
}
File = /home
}
}
That's what I tried before (along with some
permutations -- I admit to still not understanding
well how Bacula interprets Filesets.) The .backup
directory is included in the backed up files but its
contents are not.
Regex directives are another option, but IMHO they are a bit overkill
for this problem.
I thought so too which is why I asked here. :-)

[Bacula-users] How do counters work?
So I am generating backup volumes limited in size to fit on a DVD. Since I use automatic volume labeling and some backups result in multiple volumes, I include a counter in the label name. I want its value to be 1 for the first volume of the job, 2 for the second, etc. First problem: counter does not get reset per job but only when director is restarted. (This strikes me as particularly useless behavior... is not the most frequent (only?) use of counters in a label? Why would one want a value in a long-lived label dependent on an arbitrary event like a service restart? Maybe I am missing something). So I specify a catalog and save the counter in the database. I write a before job script to reset the counter to its minimumvalue. But although the script seems to be working, it has no effect. Even if I change the counter value in the database by hand after the director has started but before running the job, the job uses the old counter value. Is it possible that the director reads the counter value at startup, maintains it internally, and only writes back to the database when its incremented? Please tell me I'm wrong! -- EditLive Enterprise is the world's most technically advanced content authoring tool.

An alternative, if the hosts aren't windows would be to set up IPv6. You could apply to sixxs or one of the other tunnel vendors for a tunnel on each network and then apply for a /48 for inside the NATed network. That should be less CPU-intensive and more natural than ssh tunnels. If you haven't used IPv6 yet this would be a bit of an adventure and take a little research, but then, these days it's probably quite a timely adventure.

That's fine. But I don't understand your statement
that volume names (the things set by the LabelFormat
directive, yes?) are solely for Bacula. Why then does
the LabelFormat directive exist rather than Bacula
simply using an incrementing serial number? It seems
to me self-evident that both humans and Bacula need
to use them and they should, to the extent possible,
be constructed to meet both needs.
First problem: counter does not get reset per job
but only when director is restarted. (This strikes

Of course. I was trying to convey that *I* could
not see a use for it.
Clearly it was designed with a use
case in mind. :)
That may well be but often, especially early
in development, things that seemed like a good
ideas turn out to be not as useful as envisioned.
I asked if I was missing something as a way of
soliciting an explanation of its use. However
that was just an aside and not directly relevant
to my problem.

dependent on an arbitrary event like a service
restart? Maybe I am missing something).
We have not seen your counter usage, so we cannot comment upon it.
Sorry, I though my explanation was sufficient. I
create a (db persistent) counter and use that counter
in a LabelFormat directive. See below.
You didn't mention the docs, so perhaps these will help.

Thanks, I've read those (multiple times :-)
So I specify a catalog and save the counter in the
database. I write a before job script to reset
the counter to its minimumvalue.
But although the script seems to be working, it has
no effect. Even if I change the counter value in the
database by hand after the director has started but
before running the job, the job uses the old counter
value. Is it possible that the director reads the
counter value at startup, maintains it internally,
and only writes back to the database when its
incremented?
It is difficult to judge a script we have not seen. :)
The script is irrelevant.
Add a (db persistent) counter to a bacula-dir.conf
file, eg;
Counter {
Name = MyCtr
Minimum = 1
Catalog = MyCatalog
}
Use that counter in a Pool resource LabelFormat
directive where the SD is set up to auto-label
new volumes:
LabelFormat = ${JobName}-${MyCtr+}
Start the director (so that it will create the
counter in the database), then stop the director.
Manually change the counter value:
psql# UPDATE counters SET currentvalue=6 WHERE counter='MyCtr';
Start director and run a job. Note that the label
generated is ...-6. Change the value of the counter
psql# UPDATE counters SET currentvalue=3 WHERE counter='MyCtr';
Run another job and note that the the label generated
this time is not ...-3 but is instead, ...-7.
Obviously, if Bacula does not ever re-read the counter
value from the database, the most perfect counter-
changing script in the world run in a RunBeforeJob will
have no effect.
If you still want to see my conf files and counter reset
script, I'll be happy to post them -- I just thought that
they provide the same information I give above in a more
obfuscated form. But if you think they'll be helpful,
fine.
To recap, I am hoping there is some way of having Bacula
auto-label volumes with first label in a *job* having
a suffix of -1, and if a second or subsequent volumes
are necessary, generated with suffixes of -2, -3,
etc, with the next job starting at -1 again.
