[Bacula-users] Tape automounts but still requires mount command
Hi there, Im using Bacula 2.2.5 on centos 4.3 (2.6.9-34.ELsmp) with an LTO4 drive and tapes. We upgraded recently from an older bacula (1.36.3) and LTO1. One thing I have noticed now is that when I label or relabel a tape it auto-mounts, reports that the tape has been mounted, requests that the tape be mounted, and then sits there until I manually issue a mount command. Is this a known issue? If so what is the cause / resolution? Any advice would be appreciated!

[Bacula-users] Feature Request: Backup and Restore of Windows Encrypted Files through raw encryption functions
Item 1: Backup and Restore of Windows Encrypted Files through raw encryption functions Origin: Michael Mohr, SAG Date: 22 February 2008 Status: What: Make it possible to backup and restore Encypted Files from and to Windows systems without the need to decrypt it by using the raw encryption functions API (see: http://msdn2.microsoft.com/en-us/library/aa363783.aspx) that is provided for that reason by Microsoft. If a file ist encrypted could be examined by evaluating the FILE_ATTRIBUTE_ENCRYTED flag of the GetFileAttributes function. Why:Without the usage of this interface the fd-daemon running under the system account can't read encypted Files because the key needed for the decrytion is missed by them. As a result actually encrypted files are not backed up by bacula and also no error is shown while missing these files. Notes: ./. - This SF.net email is sponsored by: Microsoft Defy all challenges.

[Bacula-users] Increase the rate of despooling.
Hello,
Today is my deadline in the project to increase the speed of writing to
disk. But I failed. :-(
Iam just asking the same question again, If anybody can give me a lead,
it will be very helpful.
I will give the complete detail.
SYSTEM : Power edge 2650.
CPU - 1
RAM - 4GB.
OS - SLES 9 SP3.
Bacula - 2.2.7.
Tape Drive - SCSI LVD Ultrium LTO 3 Autchanger.
Database - mysql 4.1
Controller in host -Mega raid controller (perc3)
Maximum writing speed with bacula - 7.8 Megabytes/second.
Maximum Writing speed with vdump and 1024 block size - 32
Megabytes/second.
The tape library device - /dev/sg1
The tape drive - /dev/sg0( But we use /dev/nst0 for taking backup )
The Autochanger company claims the following speed of writing.
Data Transfer Rate (native): 80 MBps ( 22.8 GBph )
Data Transfer Rate (compressed): 160 MBps ( 45.5 GBph )
I feel the above is in Megabits/sec? am I correct, please tell me if
anybody is sure on this. As I get a speed of 7.8 Megabytes / sec with
compression and without compression.
The whole bacula set up works fine with our environment, like Storage
daemon,file daemon etc. And the backup process is absolutely fine except
for the speed.
I have changed the daisy chain scsi cable 3 times. No improvement in
speed.
I have tried changing the terminator also today. The same speed results.
The funny thing is I tried without terminator also and everything works
fine with same speed.
I have tried with enabling spooling ( no raid ). The spooling speed
differs from 2 Megabytes/sec to 100 Megabytes/sec but the despooling
speed lies exactly at 7.8 megabytes/second.
The despooling speed is at 7.8 Megabytes/sec for local file system,
mounted file system(tru 64 filesystem mountes in bacula server ) and any
file system of bacula client .
Does anyone find anything fishy Kindly help...
The config iam using are attached.
Thanks & Regards,
Bhaskaran

Hello John,
Many Thanks .
I have tested the raw drive speed with vdump and bs=1024, The drive
speed is around 35MB/s during vdump.
The tape drive is SCSI LVD.I had tried replacing the cable twice.but no
improvement in speed through bacula.
Does a spool file on raid0 increases the despooling speed significantly.
Because my spooling directory is /var/backup and it is not raided and no
spool size limit is set.
We use a single processor machine with 4 GB memory and the spool folder
is ext3.
Is your despooling speed with Compression or not? Either software or
hardware compression?
Thanks & Regards,
Bhaskaran

Is your tape drive scsi? Possiblty the problem is a scsi problem.
You can test raw drive speeds with dd something like:
time dd if=/dev/sda of=/dev/nst0 bs=1G count=10
If you have hardware compression on do not use /dev/zero because you
will get a very unrealistic result.

I get despooling speeds of 30 to 45MB/s on a LTO2 autochanger when
using a 2GB spool file. My spool folder is currently on its own xfs
filesystem and using software raid0. My bacula-sd machine (different
machine from the director) is a 2 processor opteron 248 with 4GB of
memory.

The message "bconsole not properly installed" means that you are running the bconsole shell script, but somehow it cannot find the bconsole executable. It looks like you have configured Bacula with sbindir and sysconfdir set to the same directory. Am I correct? That setting works for me, but running make install will still install both bconsole files: the first install is the script and the second is the executable. What is the output of make install for you? __Martin - This SF.net email is sponsored by: Microsoft Defy all challenges.

No, that's MegaBytes/second and it is accurate for LTO4 If you are only achieving 7.8 MBytes/second then there is soemthing seriously wrong with your setup. Have you tried benchmarking tape speeds using btape? LTO has very good hardware compression and I wouldn't evenn bother with software compression as the general experience is that it will slow things up - a LOT.

[Bacula-users] LTO questions - and answers.
There is a Wikipedia page covering LTO specifications, tape speeds and history. It should probably be in the Bacula FAQ and documentation. http://en.wikipedia.org/wiki/Linear_Tape-Open Note that the quoted native (uncompressed) speeds for LTO3 and LTO4 are 80MBytes/sec and 120MBytes/sec - this is significantly faster than most disk drives can throw data at them and the Wikipedia article points this out. - This SF.net email is sponsored by: Microsoft Defy all challenges.

despite the fact that we found workarounds during our discussion (on
bacula-users), I wrote a small patch:
With the attached patch, Schedule statements can include an
optional "QueueOnce" flag (i.e. QueueOnce=true, with QueueOnce=false being
default). If this flag is set, a job will only be queued once per minute.
With this enabled, one can e.g. schedule a job "first of month" as well
as "mondays"; the job will only be queued once if a monday is a first of a
month as well, and both events were queued for the same minute.
This modifies the current behavior, where jobs were queued twice.
Because of Bacula's internal logic, the _last_ "Run" statement in a schedule
wins; we can understand this as "overwriting" statements.
What do you think about this idea/code?
Oh, btw: the attached patch is against SVN trunk.
Thx, Best regards,
Bastian

[Bacula-users] Incremental promotion to full for queued jobs
I have the following schedule at a site I deal with: Full on the first saturday of every month. Incremental on non-full saturdays plus sun-fri. The problem: When the first incremental backup is run, Bacula promotes it to a full as expected since there is no prior full. However, this backup is roughly 1TB being compressed and written to an NFS share at approx. 1.5MB/s. Thus, the full backup takes over 48 hours to complete. While that is running, the Bacula scheduler kicks-in on the next day and the day after, queueing-up those day's backups. However, because the full that those backups depend on is still running and has not been committed to the catalog, those jobs are likewise promoted to fulls. When the initial backup completes, it is immediately followed by 2 more full backups which exceeds the space available. Although this can be worked around by temporarily disabling the incremental schedules, it is not ideal since the problem will only occur again when the 50-day retention period is exceeded. Is it possible for Bacula to determine whether or not an incremental job should be promoted to a full at the time the job starts running rather than at the time the job gets queued by the scheduler? That would solve my problem since any incremental jobs that were queued while their dependent full was still running would not get promoted to fulls themselves. I suspect this is a corner-case since backups, even fulls, that take longer than 24 hours (let alone 48 hours) are rare. --PLB - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Bacula-users] Increase the rate of despooling.
Hello All,
Hurrah!Completed my job right at the deadline
I tried changing the SCSI adapter to a new one... And bingo the
despooling speed is 60 MB/sec to 80 MB/sec.
Many thanks to all who replied, and special thanks to Eric And John, who
made me think of changing the terminator and scsi card.
And iam very sorry for doubting a lot on bacula for past 3 days.
Thanks a lot.

Well, I like the idea (the feature), but I'm a little concerned about the
solution you propose from several stand points:
1. I found it hard to understand what you wanted to do until I read the code,
so I am concerned that this concept could be hard to document correctly.
2. The current list of Run directives are essentially ANDed. That is Bacula
will walk down the list and schedule all that apply. I think what you really
are trying to do is to setup two Run directives to be ORed, and perhaps that
could be handled by a slightly different syntax such as:
Or {
Run = Level=Full Pool = PoolSpecial w01 mon at 8:00
Run = Level=Full Pool = Pool mon at 8:00
}
or perhaps some other keyword such as OneOf ... wouldn't that be much
clearer?
There would be a bit more work to implement this (not really hard) but
it seems to me it would be much clearer to the user.
3. It is interesting that this comes just at this moment, because just tonight
I was starting to work on the new "Duplicate Jobs" directive group for Jobs.
That is a fairly comprehensive set of directives that tell Bacula how to deal
with duplicate jobs. This too could also be a solution to the problem
somewhat like #1, but much less elegant or explict than my proposal #2.
That is if you do not allow duplicate jobs of the same level, using the
current syntax, you could put both Run statements, and if a second one
started, it would simply be killed -- a bit kludgie, but it would work
nicely.
Comments?
