We thought of purchasing a tape library with LTO6 drives which will gives us 40TB of Retention Everyone seems to indicate bacula as a good solution but when I look at the documentation, it seems 10 years outdated: http://blog.bacula.org/general/supported-autochangers/ http://blog.bacula.org/general/supported-autochangers/ That’s a blog entry. By its nature, it is dated. I can’t complain because it’s open source and I really respect the concept and know how documentation is hard to maintain, but I would like to know if I can be safe to purchase a 7000$ library, a new server running freebsd and that it will work. This is not the kind of things I have sitting in my lab J I am sure others are using LTO-6. You’ll see them pipe in here soon. Is anyone running such a setup and can assure me it can be done without too much customization and troubles. If I know it can be done for a normal poweruser (I’m not a programmer that can modify source code to fix things). I’ll invest time in learning and reading documentation, but it will be a lot more reassuring to know people done it before Bacula talks to the SCSCI interface, not to the tape library itself. If it talks SCSI to FreeBSD, it should just work. Shameless plug: come to BSDCan 2015 and we can talk more about this. ;) — Dan Langille http://langille http://langille/.org/ -- Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!

Dunno about prices in .ca but south of your border $5K will buy you a 36+2-bay chassis where you could keep a whole lot of zfs snapshots. Probably 72+2 even. What's your planned retention period? Dima ~~ I know I am going against the trend as everyone is talking about using HD as a backup device, but we are looking as something my life will depend on. If we were to loose data, we would end up with a multi-million dollars law suit and we'll just go bankrupt. As we are a SAAS solution, everything is already redundant, we can drop a plane in one of our datacenter and customer won't even notice (technically speaking) as everything is load balanced and replicated live across the sites. We have very high security with loadbalancers, IDS, DDOS protection, etc. But let say a hacker would manage to get in and play around, or even an angry employee, or... A simple rm -r / and all of our protection is gone. Our 2 distant copies and the zfs snapshots also... It's kinda hard for a hacker to format all the tapes in a library furthermore, some tapes will be put in a safe... I love the idea of using HD, so simple, cheap and fast, but if you need absolute peace of mind, I think a tape backup is much more reliable in this sense in my opinion. That's why I'm trying to see if bacula could be a good solution in our scenario. Thanks -- Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!

That's why I'm trying to see if bacula could be a good solution in our scenario. Thanks I use both ZFS and tape for backups. I back to disk, then copy to tape. The disk backups are there and used first. I only go to tape if there is a problem with the disk. You’d want to do tape verifies each night I would suspect. — Dan Langille http://langille.org/ -- Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!

I was just asking if it really is. But let say a hacker would manage to get in and play around, or even an angry employee, or... A simple rm -r / and all of our protection is gone. Our 2 distant copies and the zfs snapshots also... Well, if that's the case you might want to hire someone to look at your computer security, but in general It's kinda hard for a hacker to format all the tapes in a library furthermore, some tapes will be put in a safe... indeed. It is also kinda hard for the disaster recovery team to restore everything from the tapes locked up in a safe and between the financial damage you take from that and from the original hit you might go out of business anyway... But if you have a legal requirement to archive data for X years then tape it is. -- Dimitri Maziuk Programmer/sysadmin BioMagResBank, UW-Madison -- http://www.bmrb.wisc.edu signature.asc Description: OpenPGP digital signature -- Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!

I’ll invest time in learning and reading documentation, but it will be a lot more reassuring to know people done it before Thanks Bacula just talks to the command-line programs for your OS that deal with the library. On Linux they are the mt-st programs. There's an autochanger script which just calls the OS commands to query the library and make it 'do stuff' so really what you are looking for is whether the library is supported on FreeBSD - as long as you can script change tapes what tapes are in what slots etc you will be good to go. The default scripts work with most changers, though I had to make a couple of tweaks for my IBM for instance. Bryn -- Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
