My one comment is that if you really want to keep this data forever,
then you should *really* be making multiple copies to tape, and then
also re-reading them and comparing them against the master data.

Hi Out of curiosity, why do you do such "forklift replacements" when ZFS
supports replacing individual drives, letting the pool resilver and then
automatically grow to the new size? roy - Original Message -

Problem is not really just tape I/O speeds but the ability to get data
to it. I.e. the SD is running at about 50% cpu overhead right now
(single core) so it could possible handle (2) LTO4 drives assuming a new
SD is not spawned off per drive?
I don't really need 'rait' itself as that wou
How would the the various parts communicate if you're running multiple
instances on different ports? I would think just by creating multiple
jobs would create multiple socket streams and do the same thing.

I have been using Bacula for over a year now and it has been providing
'passable' service though I think since day one I have been streching it to
it's limits or need a paradigm shift in how I am configuring it.
Basically, I have a single server which has direct atached disk (~128TB / 112

Hi,
I'm using bacula to do backups of some remote servers, over the Internet
encapsulated in OpenVPN (just to make sure things are encrypted and kept off
public address space).
The bacula-fd is in Montreal Canada with 100mbit Ethernet. I also have
another bacula-fd in Canberra Australia on
Hi
I am using Bacula inside an Cent OS openVZ container on a
virtualization cluster. I tried with and without compression and/or
encryption and the rates are very various.
I am backing up a KVM client on the same nodes of the cluster and an
external mac client.
I can have rates of more than 30 or

Yes. If you use the time command on your tar process you will find it is
similarly slow.
Actually it's not so much random disk access speed as the fixed tim

I need to improve performance of a Job which backups 150 files (mail
and File Server).
I was compressing the files on disk in some tgz files first (tar and
gzip) ,then backuping then on tape with Bacula, i was getting about:
Job write elapsed time = 00:32:16, Transfer rate = 44.93 M Bytes/seco
Hi,
i'm talking about despooling speed (not overall). But it's the same
speed without spooling, but it's clear that over the network i can reach
max. 90MB/s.
I use 32 bit because of the OpenVZ-template but just some minutes ago, i
create the same machine as 64bit, and the speed is a little bit
Hi,
i need some tips for a backup-server.
On a new backup-server i reach a backup-speed to an LTO-4 drive of
70MB/s only.
Here the config:
bacula 5.0.3 self compiled on debian squeeze 32bit OpenVZ-vm (Proxmox as
virtualisation platform).

Hi,
On a bacula installation that I originally set up on a machine running
Debian "etch", everything was running smoothly.
Since etch has been EOL'ed, it was necessary to upgrade it, and we
recently did do an upgrade to lenny. This also involved an upgrade of
bacula from 1.38 (the version in etch
