      @BRRABill It's OKAY your server knows, and will blow up on you when you really need it to be stable.

        On a side topic, a full backup of my filer (6.5TB) took 16 hours to complete, the delta will run tonight, and should be way faster!

        But now it's done and out of the way.

          For shits and giggles I'm gonna break my home lab tonight (pull the usb)

          And follow that guide, it would be worthwhile to know if that works..

          I can't speak for v7, but I know similar instructions work for v6.5

            backup using what?

              And before you get on the omg that took forever, it was the first backup ever taken (running 6.5 XS) of this VM (since rebuilding) and the VM is near max planned usage.

                So the partition did not get set up properly by the installation routine? My guess is the "over 2TB" hypothesis again.

                I'm curious about this as well.

                When you installed XS, did it see your 6 TB array?
                Did you choose a SR location during installation?
                If so did it try to add it, and auto create ext3 like Dustin's did and fail to mount?
                or did it just ignore it since it was over 2 TB?

                if you didn't choose a SR during install, What about the LVM didn't work?

                  No, quite the contrary - my 700 GB took 30+ hours, so your system was fast as hell!

                    Yeah that is pretty quick.

                      What the literal [moderated] 700GB and 30+ hours?!

                        Are you backing up to a remote location or to a local NAS?

                        I ran my backup to an onsite NAS over the 1GB management interface.

                        If I bonded a few pairs together on the server for management (I have em to spare, probably should've) it likely would've gone way faster.

                          I have the same backup performance issues that many other people have with XS. I'm backing up to a NAS target over a 1 GB link I think my best throughput was like 35 Mb.

                          The NAS is a 8 drive Drobo Pro.

                          As another test, I setup a PC with a 5 TB SATA WD Red Drive created a share and the performance was the same. In the case of this single drive, I might have been hitting a one drive write throughput max, so I don't really count it's performance.

                              Drobo Pro is RAID 5/6. It's insanely slow. Even the B800fs is insanely slow and it is faster by a bit. With write expansion and parity overhead problems, it is very likely that the write speed of a Drobo will be slower than a single drive. At best it is expected to be only about 20% faster than a single drive and that would only be if there was no latency introduced by the parity system and on a Drobo, there definitely is.

                                XO is what he's using. With XS 6.5 there have been numerous reported issues in the backup speed performance with XO. But due to some limitation / bug of XS 6.5

                                    Right, there is a known problem that makes XO slow because of what it uses under the hood. Use Veeam and it will be fast, I'm sure. It's not an XS speed issue. It's a XAPI call speed issue that is leveraged by XO.

                                      Right, I understand that - I've never blamed XO for that performance issue. But I'm curious how Dustin got 6.5 TB backed up using XO on v6.5 so quickly? OK I probably have a backup target performance bottleneck, but there are still tons of people complaining about slow XO based backups (again because of XAPI), yet Dustin had this great backup window.

                                      Does Veeam support XenServer now? When did that happen?

                                        Has for a long time. Just not the way that you mean. Veeam has one existing product that works on XenServer and one new one just releasing. Both are agent-based Veeam backups.

                                          Scott many people would say that is agent based (because it is) it would work on any hypervisor.

                                            Oh you're talking about the EndPoint Protection (Free client).

                                            It looks like they flushed that out to a full support suite now. Great, now there's a solution for XS with Veeam.
