Re: [Bacula-users] Source Forge abusive commercial ads
We had a slightly similar case between the company I work for and another company - this was google ads, and it was actually resolved with a direct request to the company that ran the ad to keep the competition fair. I do see a possibility with this kind of action here as I believe the opensource field consists of rather well informed people, and they are likely to shoot themselves in the foot with wrong information.

However, it is possible that they do have a larger installed base for historical reasons, aside from what you might see listed in download statistics from Source Forge. I guess a broader question for Source Forge would be whether they have any stated policy or practice regarding targeting ads at competitors pages within Source Forge. Unfortunately, there are rules in marketing. One of the more important rules is: Say anything that will get you customers, as long as the profit from the customers exceeds the cost of any lawsuits. (Oddly enough, if you replace customers with votes, politicians have a similar rule.) I've noticed that this practice has been getting worse in recent years, at least in the U.S. It used to be, if you had a doctor on a commercial, there was fine print at the bottom of the screen that said something like not a real doctor or otherwise identified the person as an actor with no medical training. That doesn't occur anymore. TV ads (in particular) lie outright -- they just do it in a way that their lawyers think it's unlikely they'll ever have a sizable lawsuit occur as a result. The biggest problem, IMHO, is that the American public has ceased to notice and/or do anything about it. Yes, well I can unfortunately assure you that the same tendency is much on the increase here in Europe as well. :-( I mean, to bring this back to the original topic, if Kern complains (hell, if the entire Bacula community complains) it will probably cause very little to happen aside from a polite apology and explanation of why it is this way from Sourceforge. If, however, Kern were to start publicly researching alternatives to Sourceforge, they might take notice, as Bacula is a pretty important project with a lot of draw. I'm not going to suggest that you _should_ do that, I'm just saying it might be more effective. If Sourceforge is unwilling/unable to force their advertisers to be honest, perhaps some other project hosting service would be a better fit anyway? Just so my position is clear: I don't really like having commercial ads posted all around the Bacula project page, but can accept it to a certain point. However when I see ads for Zmanda that state it is the most popular Open Source backup software in the world, I sit up and take notice. As Chris says, possibly (and I stress possibly) they have a larger installed base (though I doubt it), but they were not saying they had the largest installed base, and the best statistics on popularity of Open Source projects hosted on Source Forge is SF's own statistics, which seem to imply that Zmanda is *far* from being the most popular Open Source backup program. I'm not claiming that Bacula is the most popular as there are a good number of other programs (IMO, not in the Bacula class) that are much more popular than both Bacula and Zmanda/Amanda. Anyway, I would like to give Source Forge a chance to respond before making any decision, but if the misleading wording in the latest ads (not always there) remains, I'll definitely look into different hosting possibilities. - Take Surveys.

[Bacula-users] restore with two autochanger using same MediaType
Hi List, we have two autochanger, booth changers using SDLT-320 as MediaType. version of bacula is 1.38.11. running a restore: The job will require the following Volumes: INC008 Run Restore job JobName:RestoreFiles Storage:Overland1 When: 2006-12-12 12:42:19 OK to run?

Same error using bacula-1.38.2 on FreeBSD 4.11 here. Just to clarify the problem - looking at the bacula code it seems to me like the follwing happens: - fd extracts file A - d sets the attributes/flags for A - d restores file B which is a hardlink to A The last operation fals because A has the SF_IMMUTABLE (system immutable/schg) flag set. I'm speculating this will occur on all UNIX/linux/BSD platforms which have an IMMUTABLE attribute/flag for files. Can somebody confirm this? Looks like bsdtar had this problem too: http://lists.freebsd.org/pipermail/freebsd-current/2004-May/027884.html And even (Net?)BSDs restore: http://mail-index.netbsd.org/current-users/2004/10/11/0005.html The solution proposed is to keep file flags in a list and set them after all files have been restored, so that all hardlinks can be created. Though it is probably enough to do this for hardlinked files. Looks like this would make the restore code even more complicated. But what is the solution if you restore a file from an incremental backup which is a hardlink to an IMMUTABLE file? bacula could clear the IMMUTABLE flag for creating the hardlink and re-set it afterwards. But this is not possible if kern.securelevel 0. I guess it would be wrong to do so anyway, because it undermines the security of the system. After all files are set IMMUTABLE for a reason. Consider the fd crashes for some reason after it cleared the flag... is there an atomic way to do this? My solution for restoring a freebsd system right now is to reinstall the base system after the restore (make buildworld installworld). Regards, Georg - Take Surveys. Earn Cash.

Same error using bacula-1.38.2 on FreeBSD 4.11 here. Just to clarify the problem - looking at the bacula code it seems to me like the follwing happens: - fd extracts file A - d sets the attributes/flags for A - d restores file B which is a hardlink to A The last operation fals because A has the SF_IMMUTABLE (system immutable/schg) flag set. I'm speculating this will occur on all UNIX/linux/BSD platforms which have an IMMUTABLE attribute/flag for files. Can somebody confirm this? Looks like bsdtar had this problem too: http://lists.freebsd.org/pipermail/freebsd-current/2004-May/027884.html And even (Net?)BSDs restore: http://mail-index.netbsd.org/current-users/2004/10/11/0005.html The solution proposed is to keep file flags in a list and set them after all files have been restored, so that all hardlinks can be created. Though it is probably enough to do this for hardlinked files. Looks like this would make the restore code even more complicated. Not only is it more complicated, but it can be very expensive. Suppose you are restoring a million hard linked files. That could mean that you need you will need to keep a list that could amount to hundreds of millions of bytes (you need to keep at least forward links, the full path and the file, as well as certain of the file attributes). If you are restoring 5 or 10 million files, it could even be worse. In addition, if you have multiple files linked together (i.e. more than 2), it would add more complication because when hitting the second linked file in the list, the real file would already be marked immutable. You can solve that by having a doubly linked list in binary order, but then the computation costs go way up. But what is the solution if you restore a file from an incremental backup which is a hardlink to an IMMUTABLE file? bacula could clear the IMMUTABLE flag for creating the hardlink and re-set it afterwards. But this is not possible if kern.securelevel 0. I guess it would be wrong to do so anyway, because it undermines the security of the system. After all files are set IMMUTABLE for a reason.

There was some discussion about multitape-changer recently. Use some of
the list archives to see if there is relevant information for you...
This is my configuration:

I don't think this is how multitape-changer works. I never actually used
it, but I think it simulates a one-drive autochanger with a number of
slots equal to the number of drives you have.
Device {
Name = tape1
Drive Index = 0
Media Type = 4mm
Archive Device = /dev/nst1
AutomaticMount = yes
AlwaysOpen = no
RemovableMedia = yes
RandomAccess = no
AutoChanger = yes

Media Type = 4mm
Archive Device = /dev/nst2
AutomaticMount = yes
AlwaysOpen = no
RemovableMedia = yes

SDPort = 9103
Password = P00io9
Device = multitape0
AutoChanger = yes
Media Type = 4mm
Maximum Concurrent Jobs = 1
}
but:
1 - no automatic startup link has done by bacula, I have to link /dev/nstx
to /dev/changer0 manually
Sure, Bacula doesn't create device nodes for you.
2 - no automatic change has done by bacula
So the autochanger setup didn't work. What does btapes test command tell
you?
3 - look at the update slots here ...
chronos bacula # bconsole

3306 Issuing autochanger slots command.
Device multitape0 has 0 slots.
No slots in changer to scan.
You have messages.
So the multitape-changer setup is not correct. See that thread I
mentioned for more information.
Or hope to find someone who actually uses that... (or pay me :-)
seriously, I didn't get the impression that the suggested multichanger
script is easy to use).

Are someone experienced with this script? What's the best configuration?
Thanks in advance.

If the OS permits Bacula to remove the immutable bit, then it would be possible to remove the immutable bit before hardlinking a file, and then put it back, and this without keeping any lists. - Take Surveys.

Then you can set the attributes after the restore is finished. I'm not saying this is easy to implement, though. Off hand, I would say that the FreeBSD guys have worked themselves into a big hole. They have violated the rule that says that root can do anything. Using linux with MAC (mandatory access control), or one of the other dozen of similar implementations, basically does the same thing. The FreeBSD problem is probably just one of many which will arise with all those policy frameworks. It appears like nobody thought of the implications for backups and especially restores this causes. Maybe a command to mark a directory tree restorable, i.e. so that all policies have no effect, would be nice. But that's just a wild guess... Regards, Georg - Take Surveys. Earn Cash.

[Bacula-users] Removable Disk Howto revised
Attached is the latest version of the Bacula Removable Disk Howto in HTML and LaTeX formats. The attachment also includes the vchanger shell script and an example config file this time. The vcahnger script was updated to fix a bug (thanks to Michael Fung for pointing that out) and to keep the bacula-sd user as owner of files/directories when run as root. Also, a purge command was added to delete all volumes on the currently loaded magazine and then re-create them. In addition to deleteing the volume files for each slot from the magazine's filesystem, a 'delete volume' command is piped to bconsole to delete the volumes from the catalog. A 'label barcodes' command is then piped to bconsole to recreate the volumes and place them in the Scratch pool. In effect, it purges and recycles the entire magazine. Use with extreme cation! Enjoy!

Re: [Bacula-users] problems with hardlinks to schg secured files on FreeBSD on restore
(I have a patch below.)
The workaround with NetBSD's restore(8) simply was to add a restore option
(-M) that told restore never to set the file flags (via chflags(2)) and
just write the specification for the setting the flag using mtree spec
format. Then the admin could choose to run mtree later to set the flags
using that generated specification.
But if the file already has immutable set before any restore, you may be
out of luck.
Just for those who don't know about this with BSD: a security level can be
set which stops even root from turning off these flags and the security
level can't be lowered by root either. The only way is too reboot the
computer and make sure it boots up without the security level raised (boot
first into single user at physical console for example).
Another option which was only mentioned very briefly in this thread is to
try what FreeBSD's restore(8) does (but NetBSD does not appear to do).
If the link(2) fails, then assume that maybe there is a file flag
preventing this and then do (from FreeBSD's sbin/restore/utilities.c):
if (stat(existing, s) == 0 s.st_flags != 0
chflags(existing, 0) == 0) {
ret = link(existing, new);
chflags(existing, s.st_flags);
}
Here is an untested patch (or at least an idea :) that should help those
who don't use raised securelevel. This patch needs some debug output for
both chflags introduced here.

As I mentioned in my earlier response, Bacula has to work around the
broken Windows concept of drives. Bacula doesn't do drives.
In order to work around it, Bacula creates a directory for each
drive, as you can see above in your ls, it created a c: directory
in the backup volume.
So, try cd c: then do another ls. An example for one of my systems:
cwd is: /

I setup service recovery (restart) after 15 minutes, but the end result is that the service is not running and backups are failing. The file daemon services are running under a special sys_backup user identity which is a member of the Backup Operators group and has read permissions to the folders to be backed up.

I'd be glad if you set your mail client to wrap lines at about 70 chars, and I'm sure others would like that, too. More to the point: The term can be freely interchanged seems to be the problem. From Baculas point of view, this means that there's no penalty in using any device. In your situation, there obviously is. i'm running bacula with one director and two storage-daemons at two different locations (~20km far from each other and booth with an Overland Neo 2000 SDLT attached). my goal was to store the tapes cross-side and restore from the offsite-tapes using the offsite-storage, this is why i'm using on booth location the same media-types and pools. Ok, I understand that setup. I even see a solution for it: Set up your storage devices with different media types. When transfering tapes, change the media types of the tapes according to the location they're going to. I could come up with a simple script to do that. i want to put the tapes in any storage, then update slots and running the restore, without thinking about in which storage the tape is. (i can handle the problem, but my teammates will kill me, when i return from 4-week-holiday) They should be glad you returned :-) Well, it might be time to ply with 1.39.wherever-we-are-today for you and test this... I'm sure Kern would be interested in the results of your tests. As far as I know, there's a better chance for this to work as it should in 1.39. when its only requires an update of the director, maybe i can test it, but i can't update my complete bacula installation to a beta version . It does a require an update of DIR, SD, and catalog database schema at least - so this is not an option for you. That said, I think it's quite stable, and I understand that Kern is going to relese 1.40 this year, so you might consider and upgrade soon, anyway. Arno Best Regards, Thomas btw. i need something like a column location in the Media-Table, can i simply add one, or will this cause troubles with future bacula-updates? currently possible locations of my tapes are: Overland1/Overland2/Safe1/Safe2 and Offsite, and i want to handle this inside of bacula. - Take Surveys.

Re: [Bacula-users] [Bacula-devel] problems with hardlinks to schg secured files on FreeBSD on restore
The patch I sent was not correct because ofname and olname where mixed up
when doing the flags work. I fixed this now, and I tried restoring
my /usr/bin. It now created the hardlinks, but gave me errors that the owner
and times of the hardlinks are not setable (because of the same thing)
How relevant is setting those two things anyway? Is it possible that a hard-
link has other time stats or belongs other owner/groups as it's sourcefile?
If those two atributs has to be considered for hardlinks too, a similar patch
has to be applied to atrribs.c I'd say. W/o looking into it I'm not sure if
there is olname defined?
I'll continue testing tomorrow *yawn*

Well, 1. Bacula isn't a real enterprise backup system, so workarounds are just fine considering there is a lack of programmers. 2. I don't see that a lookup to a media table would solve anything. Some other concept is needed. Currently, in Bacula one either locks the volumes down specifying a unique MediaType, or you specify a generic type in which case Bacula assumes the volumes can be mounted on any compatible drive. Maybe I am missing something, but it seems to me that you want something where Bacula automatically figures out when you would like to transfer tapes. 3. If you want Bacula to be able to modify Media Types during an update slots command, that is possibly a solution.

I've attached 2 patches (will both apply with some offset)
patch-src-findlib-create_file.c
Try to unset file flags of the sourcefile when the hardlink failed.
Retry to hardlink then. If the hardlink fails then again, restore the
file flags of the sourcefile. If the hardlink was created w/o errors,
restore the fileflags of the sourcefile.
patch-src-findlib-attribs.c
when restoring a symlink, use lchflags to restore the file flags
defined for the symlink (new feature)
when restoring a hardlink, don't call chmod, chown, utime because it is
a hardlink and don't have such attributes (as far as I know, if someone
with more FS-foo can step up and confirm this?). Changing this
attributes will change the sourcefiles attributes which is probably not
what is wanted here anyway

Hello, I haven't yet looked at the patches, but here are a couple of preliminary comments. I'll take a careful look at the patches later today. On Wednesday 13 December 2006 07:54, Oliver Lehmann wrote: Kern Sibbald wrote: Please fix it up correctly, then send it to me in the same diff format versus the current CVS, but please send it as an attachment to avoid the possibility of word wrap. I'll then take a look at putting it in the code. If you send it in the next few days, it will probably become part of 1.40.0 ... I've attached 2 patches (will both apply with some offset) patch-src-findlib-create_file.c Try to unset file flags of the sourcefile when the hardlink failed. Retry to hardlink then. If the hardlink fails then again, restore the file flags of the sourcefile. If the hardlink was created w/o errors, restore the fileflags of the sourcefile. OK, this sounds very good. Thanks. patch-src-findlib-attribs.c when restoring a symlink, use lchflags to restore the file flags defined for the symlink (new feature) when restoring a hardlink, don't call chmod, chown, utime because it is a hardlink and don't have such attributes (as far as I know, if someone with more FS-foo can step up and confirm this?). Changing this attributes will change the sourcefiles attributes which is probably not what is wanted here anyway I'll have to think about this a bit more. However, I don't think it is correct to skip setting the attributes. To understand hardlinks, the first thing is to realize that the name is slightly misleading. A hard link is not really a link. The data for the two files the attributes are one and the same. The situation is very different from a softlink where there is a separate directory entry that points to an existing file. Thus to properly restore a hardlink you must also reset the attributes or you could potentially end up with incorrect attributes (owner, modes, ...). - Take Surveys. Earn Cash.

Ok, but from my understanding setting attributes on a hardlink changes the attributes of the inode the hardlink is pointing to, like for normal files which are technically hardlinks too. So changing attributes for n objects pointing to the same inode is like changing the attributes n times for the same object or is this wrong? If you think attributes for hardlinks have to be restored as well, the fix for src/findlib/attribs.c has to be redone. I can do so but I still think ;) - Take Surveys. Earn Cash.
