Re: [Bacula-users] TLS Config Problem (FD did not advertise required TLS support.)

[Ana Emília M . Arruda]

Hello Javier,

Did you solve this?

ssl=0 means that no TLS connection is being used. Since TLS Require = no
for both director and storage daemon, it seems that they are unable to
establish one and then are communicating with no encryption.

You can always run tests to verify your certificates:

open a server-side ssl connection to listen to 9102:

openssl s_server -accept 9102 -key betelgeuse.canonigos.es-daemon.key -cert
betelgeuse.canonigos.es.crt -CApath /usr/local/etc/ssl/ Verify 0

try to connect from a client:

openssl s_client -connect betelgeuse.canonigos.es:9102 -key
director.example.com.key -cert director.example.com.crt -CApath /
usr/local/etc/ssl/

Regards,

Ana

Re: [Bacula-users] LTO-7 tape drive settings in bacula 7.4.0

Hi,

You're welcome. Could you please send us some log output (mainly the parts
telling that the volume is being marked Full and changing to another one in
the same pool)? Maybe this could help us to understand better this issue.

Best regards,
Ana

Re: [Bacula-users] Bacula - Sqlite to Mysql

[Randy Katz]

you can copy your config files to another directory, typically a
reconfigure will not remove config files.

as for mysql you should find all the pertinent db creation scripts in
/etc/bacula. The part that pertains to

the database is usually in bacula-dir.conf and looks something like this:


Catalog {
  Name = MyCatalog
# Uncomment the following line if you want the dbi driver
# dbdriver = "dbi:mysql"; dbaddress = 127.0.0.1; dbport =
  dbname = "bacula"; dbuser = "bacula"; dbpassword = "p24b2p"
}

So if you created a mysql database called bacula, gave the bacula mysql
user access to it with a

password of p24b2p and used the above instead of what is in there and
then ran the create database command

create_bacula_database that should get you on your way.

[Bacula-users] Bacula - Sqlite to Mysql

[Emporio]

Hello,

could somebody please help me with reinstall Bacula from SQLlite to MYSQL. I 
think my biggest problem is that i dont have installed Bacula with MySQL 
support. I am afraid to use dpkq reconfigure because it maybe could delete my 
config files. 

Is it true?

The defaults for both of those should work out of the box.  However, by 
increasing the Maximum Block Size, you can probably improve the speed of 
writing to the tape.  This is, of course, optional.  I would still not set the 
block size any larger than 512K though.

Hello,

The tape probably got an error.  You should be able to see if there were 
problems by looking at dmesg output and Bacula output for the job that marked 
the tape full.

The error, if there was one, is very likely coming from the fact that you set 
the block size too big.  I believe that anything more than 512K will probably 
not improve performance much but it will increase significantly the chances of 
a write error.

Try running some tests with 512K max block size and see if the tape fills up 
correctly.

Best regards,
Kern

Re: [Bacula-users] LTO-7 tape drive settings in bacula 7.4.0

[Alan Brown]

To rule out a bad tape:

Before removing  the tape from the drive use smartctl -A /dev/sg(generic
of drive) to count the corrected errors

You can do this whilst the tape is being written to. If the numbers are
increasing rapidly, either the tape or the drive is dirty.

If it keeps occuring on other tapes, after running a cleaning tape then
the drive is dirty and will need replacing under your support contract.

Qualstar-sourced tapes are all run through a cleaning machine before
repackaging.

Other tapes sometimes come with a bonus of various contamination types
(I've had this happen) and drives themselves are susceptable to picking
up gunk if it's in the local atmosphere - it gets worse if humidity is low.


A clean tape and clean drive will generate almost zero errors. Once
contaminated the numbers just keep increasing.

This case is not possible, because all backup (Full and Differential) are
in the same volume, if you recycle volume, bacula will recycle entire
volume.

Yes. You need to create a Pool for the Full backups with a long  retention
and another Pool for the Differential backups with a shorter retention.

[Bacula-users] Deleting DIFFERENTIAL Jobs from Volumes

[Larrybwoy]

Hello again,

A new question : Is there a way I can set up Bacula so that it recycles only 
the differential jobs from a volume? For example, I have one volume that has 
the initial full backup in it and 1 other differential job. Can I set it up so 
that only the differential job in there gets recycled every hour? 

OR, say i have the flag "User Volume Once = yes", and I have 1 volume which is 
the first  full backup, then 1 other volume which represents the differential 
backup, can I set up recycling only on the 2nd volume? I don't want to be doing 
a full backup every hour because of retention times, and I only want to do a 
full backup ONCE, then only differential.

I have tried this (without the Use Volume Once flag) with a 3 hour retention 
period (since it takes about 2 and a half hours to do a full backup for my 
filesystem, and if I set the retention period lower than that then bacula runs 
the next differential job(which is hourly) as a full job...)  and the problem 
is that after those 3 hours are up bacula creates a new full job in the first 
volume, since it sees it as being expired. 

I can't seem to figure out a decent plan using Bacula for my specific needs, 
it's driving me crazy.

Re: [Bacula-users] LTO-7 tape drive settings in bacula 7.4.0

[Ana Emília M . Arruda]

Hello,

Have you checked if you do not have a Maximum Volume Bytes configured in
your Pool resource?

Best regards,
Ana
