Re: [Bacula-users] Issue with concurrent jobs in disk based auto changer

There is a separate LAN between Bacula clients and the Bacula server 3. I will try shifting the bacula-sd from Bacula server to Filer as suggested by both of you. We have a setup with ZFS on linux storage mounted directly on bacula server, that works pretty well without spooling, but in your setup I would put a large(-ish, dep. on your volume size and number of concurrent jobs) SSD in the bacula server and spool data to it. That way bacula will stream complete volumes from spool to the filer at your full bandwidth and avoid (potentially) many small writes over NFS.

Yeah, but rolling upgrades are a PITA anyway so what else's new. Also, linux-to-linux you're pretty much on the same zfs version on all boxen, and so far I have not seen any problems between e.g. centos 7/zfs 0.8.1 and centos 6/zfs 0.8.3. Also, how do you backup the backup box itself? I don't. ;) Yes, it you want all your change history in a tape archive in a vault somewhere far away, that would be a problem because snapshots are not visible to your tape backup software. But then you may want to consider putting your stuff on GitHub: it's better at tracking version history than incremental tapes, easier to restore, and might actually cost less than the tapes and the vault and the monkey to cart the tapes there and back.

If you would be so kind and have an idea how it could be implemented in bacula and so kind to describe it on this list it would be implemented by developers. I don't have any idea how it could be implemented *in bacula* since I never looked at any bacula code. In general sending the same stream of bytes to two different places instead of one is not exactly rocket science. I guess it and can be implemented in several places, e.g. special storage inside SD, or two different SDs. I would probably send to two SDs at once because it allows for more flexible setups: the 2nd SD can write to "the cloud", it can be on the off-site box, etc. Whereas amanda-style RAIT device only protects against single disk/tape failure.

But as Davide suggests, you could copy the job(s) afterwards. I'm doing something along these lines; my backups go to disk, but Full backups then get post-copied to removable disk sets. And when the disk decides to go titsup in the middle of a job, you lose everything since the last full. I have a post-script that rsyncs the current "magazine" to a spare disk, this way I only lose the last backup. Amanda had "RAIT" since forever.

Hello
I am used to this principle with Linux but I don't understand why it just takes
it when Bacula is working and it slows down the server so much that I can no
longer access it in ssh.
Typically,
- failing drive,
- saturated network,
- broken name resolution.
If it only happens when bacula is running, I'd first run `iostat -dmx 5
5` and see if the drive where "File1" is located is clocking high wait
time and near-100% utilization.
If yes, throw it away and replace with a TLER ("NAS") HDD.

But when it is a second off-site copy then it becomes harder to maintain a low price. Then something like S3 will help a lot. That is why/when I started looking at amanda and bacula. My university runs a backup service where we only pay for storage. We ran with it for a couple of years and the money quickly added up to where it was cheaper to buy a new storage chassis full of sata drives *every other year* and have it co-located at CompSci a few blocks away. The only way I can see this working out is you absolutely must have your backups of-site and have absolutely nowhere to colocate your backup box, or if your colo charges will be comparable to S3.

I had already thought about that, but because i have to format both RAID-arrays for that (and therefore move some other stuff on that disks around) i first tried the autochanger... Use ZFS if you can: you get raid, lvm, and a filesystem in one coherent package.
