[Bacula-users] Noob user impressions and why I chose not to use Bacula

[Jesse Molina]

, for example, 
the current state of a system just backed up. With a bootstrap file, 
Bacula can restore your system without a Catalog. You can create a 
bootstrap file from a Catalog to extract any file or files you wish.
...
If you have used the WriteBootstrap record in your job or some other 
means to save a valid bootstrap file, you will be able to use it to 
extract the necessary files (without using the catalog or manually 
searching for the files to restore).
...

But then...

The bextract program does not restore access control lists (ACLs) to 
Unix machines. 

How do you reconcile this?  Both can not be true.  Imagine a Linux 
system being restore without file permissions.

Bacula's default block size is 65KB is getting rather small.  My 
five-year-old DLT S4 drive can take a 16MB block.  At least this can be 
configured easily.

[Bacula-users] Anyone out there using an LSI20320-R for your tape drives/libs?

[Jesse Molina]

Hi all.  New Bacula user here doing my setup and install.

I am trying to get a new drive working with an LSI20320-R card.  The -R 
is for RAID, but it only does RAID 0 or 1, so I was guessing it would be 
okay, but after some drive errors I am not so sure.

I am having various trouble, which I am currently blaming on either a 
bad drive, tapes, cable, or HBA card.

The LSI20320-R is a single channel Ultra320 PCI-X card.  EBay is flush 
with cheap units; $10 each, shipped.  I bought two to have a spare.  =)

If anyone out there is using this card and has feedback, it would make 
me feel better.

My host is Debian GNU/Linux AMD64.



Here's what lspci says about the card:

03:06.0 SCSI storage controller: LSI Logic / Symbios Logic 53c1030 PCI-X 
Fusion-MPT Dual Ultra320 SCSI (rev 08)

Linux driver module is mptspi

[Bacula-users] Error writing final EOF to tape. Bad tape suspected.

[Jesse Molina]

This looks like a bad tape.  I'm new to Bacula.  Can I get a second 
opinion, please?

Here is some info about my setup:

Debian GNU/Linux, kernel 3.0.0-2-amd64.

Debian packaged Bacula version 5.0.3-1+b1.

This is a Quantum DLT S4 drive attached to an LSI20320-R card on a PCI 
32bit bus slot, Gigabyte GA-MA78G-DS3H desktop motherboard.  The 
hardware has been in use for a few years and is stable.

The thing is, tar isn't having this problem with the tape in question. 
Yes I restored and compared all of the files.  The backup fileset was 
the same.

Quantum also has a nice toolset called xTalk and I have run extensive 
read/write tests against the tape and a 23-minute long device health 
check which did not indicate any kind of error.

Below are three separate backup attempts on a fairly small set of data. 
  You will see the Bacula log info, and then the kernel log info.  This 
is the same tape.  When I tried another tape, the backup succeeded 
without the error.  Note that /var/log was included, so the file set 
size changed(probably grew) slightly between attempts.

It looks like the error happens when Bacula is trying to write the end 
of tape.
