I’m running ElectricEel-24.10.0.1. I have a single pool with some shared volumes and approximately 210tb of stored data. I’m looking at creating a snapshot to tape. I have an LTO-8 library that I’d like to use. I’ve read NickF’s incredibly helpful discourse on the topic ( Using LTO Tapes to backu…

[image] Ricky_Smith: It just seems like I should be able to do it natively through TrueNAS. I understand your frustration–I share it around the lack of drive support for drive-native encryption, which has nothing to do with TrueNAS–but some of this is a limitation of how LTO currently works a…

With LTO, the device drivers generally need to be running on the host to be seen. This is especially problematic for Macs since macOS does this through a system call rather than exposing a device under /dev. You may or may not face similar problems trying to expose host drivers in a container, and w…

That’s interesting advice, and I thank you for it. My concern is that, because it’s a robotic library, mounting it as an LTFS destination removes the backup client’s ability to communicate with the library’s tape swapping mechanism and barcode tracking system. Increasingly, it looks like I need to…

[image] Ricky_Smith: It just seems like I should be able to do it natively through TrueNAS. this, right here. there is no nice way to do this, and it only gets much worse much quicker if you have an library/autoloader. I would love if there was just a way to set up an LTO library that points…

I’m marking your post as a solution. It isn’t what I want to hear, but your expertise matches what I’ve been reading (and then some). My plan from here is to stand up a Windows host on the network with an HBA for the library and run something from that to consume the data via SMB. I had hoped for…

[image] Ricky_Smith: I created a Windows VM with the intent to run VEEAM on it, but couldn’t find a way to pass /dev/st0 to the VM. Edit your VM and go to Devices. The only (and the best) way to do that would be to pass the whole HBA to the guest using PCI-E Passthru. This does unfortunately …

Thanks, @Stux . I had referenced that article in my OP.

Good information, Nick. I have a second HBA, but I’m out of slots in my server to install it. Maybe I’ll move things around a bit and see if I can gain a slot. Thanks again!

[image] CodeGnome: I’m not sure that ZFS snapshots capture sufficient data to restore from tape Of course they do, they would be pretty damn useless if they didn’t. Managing snapshots independently of ZFS is always going to be a pain, but there’s nothing keeping you from just streaming snaps…

[image] ericloewe: Managing snapshots independently of ZFS is always going to be a pain, I understand what you mean here, but I’m not sure I agree. In a world with non-homogeneous file systems ,having an agnostic third party like Veeam manage your backups is not a pain. Rather, it’s a differ…
