Re: [Bacula-users] Netware shares backup

 Hello,
 
 i have a bacula Installation, wich will backup Netware CIFS shares. I
 have mounted the shares with ncpmount wich is included in the ncpfs
 package. If i start a job to backup the shares, i get a data rate of
 5883.6 KB/s. If i start a windows job i get a date rate up to 17000
 KB/s wich is more faster than the Netware job. Has anyone a hint why
 the Netware backup is so slow and how i get more performance? Is the
 problem on the Netware side or on the bacula side?
 

I want to coin that it might in the middle, on the network.

I don't known the setup of the original poster, but let me guess.

The 17000 KB/s is from the fileserver and goes straight to a client.

The  5884 KB/s has to travel a way like
- the fileserver
- the computer where it is ncpmounted
- the computer where the Bacula storage deamon is
- and maybe to some network attached storage

A longer network (de)tour has it's throughput price ...

 Hi

 Despite Bacula is quite easy to operate I got a small problem.

 On a server I run a script before the backup is started (mysqldump).
 Sometimes it happens that the script fails on a part of the job. The
 situation is then that data is not complete but that is better than
 nothing. I want the backup to continue and do the actual backup. When
 the job is finish I want to have a failure report by email if the script
 failed.

 My beforeScript looks like this:

  RunScript {
  RunsWhen = Before
  FailJobOnError = No
  RunsOnFailure = yes
  RunsOnClient = Yes
  Command = /etc/backup/dump_all_db
  }

 The FailJobOnError makes the backup continue despite the error, but
 the error report says OK.

 How can I get failure report and also a backup of the data which is OK?

 Make the /etc/backup/dump_all_db script do the reporting?

   Cheers,
   GaryB-)

Re: [Bacula-users] Bacula Linux and the LTO-4 tape speed

 for me (with LTO-3) increasing Maximum block size has had quite the
 impact on performance.

 Sadly, with the new setting I had trouble reading my tapes so switched
 back to the old configuration.

in Linux, you can configure your tape drive to accept variable block
size with mt setblk 0.  without a variable block size, I have found
that you need to set minimum and maximum block size to the same value,
or else Bacula may write an, e.g., 66 KiB block if you have configured
minimum block size to be 64 KiB.  at least my LTO-5 drives will not
accept a 66 KiB write after mt setblk 65536.

oh, and I'm using max block size of 512 KiB, since that is what HP's own
tape testing tool (hp_ltt) is using.
