[Bacula-users] Handle files that have st_ctime changed often in bacula
Hello,
I have a problem when bacula tried to backup a folder that contains some
files changed often.
For example: i backup the folder /var/samba
And for some reason, some big files in this folder are accessed by other
programs and therefore their attribute chang (st_atime) is changed. As a
consequence of that, bacula backups that file in the following incremental
backup.
The final result is that those such files eat up all of my disk space.
In my opinion, i have 2 ways to solve that problem but i dont know if
they're feasible.
1) Do a full backup, but incremental backup don't include those files . Is
it possible to create a fileset for a full backup and another fileset for
the incrementals.for that case ?
2) In the fileset, those files will be treated in a different way like the
configuation below:
FileSet {
Name = fs_samba_system
File = /var/samba
Include {
Options {
signature = SHA1
onefs = no
Wildfile = *badFile.pdf
Exclude = yes
}
}
Include {
File = /var/samba
Options {
WildFile = *badFile.pdf
Signature = SHA1
mtimeonly=yes
}
Options {
Exclude = yes
RegexFile = .*
}
}
} Is it right for what i described above ?
and is there another better solution ?
Thanks in advance,
Truc

Re: [Bacula-users] Problem of is waiting on max storage jobs and is waiting for an appendable volume
Thanks to Ana,
It works without any problem now.
But what do you mean Label Format clauses are strange. Are you sure
whether the same volume is reused ?
Does bacula detect Maximum Volumes greater than 1 so il will automatically
add the number after ?
For ex: monday-2014-11-17001 and monday-2014-11-1700.

Also, I think those Label Format clauses are strange when used with

(e.g. monday-2014-11-17), not the recycling date.

Yes, you are correct. That was exactly what ocurred. If you want a 13
days
retention period for your incremental jobs, you will have to configure
a Maximum
Volumes of 2. Also, you have different retention periods for incremental
and full backups (me too). So I would recommend you to have different
pools
for your full and incremental backups.

Yes, the actual value is 13, and it caused the problem.
In my opinion, the first week , bacula created successfully the monday
incremental backup, and its status was USED but it had to be wait 13
days.
During that time, in the second week, bacula tried to write again to
the
same volume that is not pruned so it caused the problem. And maybe it
hangs
the remain jobs.
Is it right ?
Or do you have any suggestion ?

Hi Sieu,
If you have changed the volume retention for your volumes in the
pool
configuration, this change only is applied to new volumes created.
For the
volumes that were already in the catalog, you should run an update
volume
through bconsole and change this value there too.
Since you said that you have changed from 6 to 13 days your retention
periods, I´m supposing maybe this is your problem with is waiting
on
max storage jobs.

Re: [Bacula-users] Recover full backup from the incrementals

But now, if i have 2 full backups like

Sunday at 22:00
}
After 3 week, i have 3 full backups named even_sunday_1, odd_sunday_2 ,
even_sunday_3.
If i lose odd_sunday_2, can i recover it from even_sunday_1 and the
incremental backups during 2 weeks ? The incrementals of the second week
are based on the odd_sunday_2 so can they be applied to even_sunday_1 ?
Thanks in advance,

Really it would come down to what files you needed to restore...
If the files you need are all in the incremental then Bacula will restore
them without touching the full backup at all.
If you need to restore a full filesystem including files that will not
have changed since the last full, you will possibly loose some data,
depending on what has changed.
In the scenario you are talking about (w2 being damaged), you could do a
full restore of w1 plus the incrementals that depended on it which would
take you to the end of Saturday, and then you could do a restore of all the
incrementals going forwards from there. You would miss any data changed
after the Saturday incremental run after w1 but before the full w2 was run
- the first incremental after w2 would have caught any changes after w2.
So you would loose about a day's worth of data - depending on what type of
data changes you are dealing with that may or may not be acceptable to
you. The restore would be more complex than just saying restore
everything to the specified date.
Whether or not this would give you a usable restore point depends heavily
on your workload - if you are dealing entirely with files that are updated
in place you would be fine, the end result would be the same as if w2
wasn't damaged at all. If you are dealing with something like a busy mail
server with a bunch of maildirs - a large number of files being created and
deleted regularly, you would have a mess. You'd be missing a day's worth of
mail plus you potentially would have 'undeleted' quite a bit of data since
you would be restoring files that may have been later deleted.
So the short answer is 'it depends' - this will be true of nearly any
backup software when using the approach you describe.

Hello,
I have a question about bacula's recovering mechanism.
I do an full backup every week, and the dailly incremental backups,
specified in the following configuration :
Schedule {
Name = schedule_test
Run = Level=Incremental Pool=Monday Monday at 22:00
Run = Level=Incremental Pool=Tuesday Tuesday at 22:00
Run = Level=Incremental Pool=Wednesday Wednesday at 22:00
Run = Level=Incremental Pool=Thursday Thursday at 22:00
Run = Level=Incremental Pool=Friday Friday at 22:00
Run = Level=Incremental Pool=Saturday Saturday at 22:00
Run = Level=Full Pool=fullBK Sunday at 22:0
}
After 3 weeks, i have 3 full backup named w1,w2,w3 corresponding to each
week.
If for some reasons, the backup w2 is damaged, would i lose all the
incremental backup in the second week from monday to friday ?
And can i restore the backup w2 with w1 ?
Thanks,
PHAM Ngoc Truc

[Bacula-users] Recover full backup from the incrementals
Hello,
