      @DustinB3403 Hmm. You should have a VDI snapshot somewhere in your SR view (that's not visible inside the VM view, only on the SR one)

        I just ran a test Delta Backup and here's the disk

          You mean in the target repository correct?

          Which I have 0_1452537852062_XenCenter_2016-01-11_13-44-04.png

          So I do have a VDI in there, but nothing shows within XC.

          Which is what I thought you meant (and @johnhooks)

            @DustinB3403 No inside the SR (the XenServer SR)

            edit: the SR where reside your VM disks

              Under the main view for the actual hypervisor in XO, if you look at the storage section and then click on the repository that holds the VHDs. It will list all of the drives. They should be in there.

                    Here's another question, since they are deltas, are they thin provisioned or is it a full copy of the VM. For example, a 300GB file server disk, is the XO_DELTA... drive a full 300GB like it says or only the changed amount?

                      Now if only @olivier would stop hiding all of the critical information we'd all be better off!

                      😛 😄

                        @johnhooks Depends of your XenServer SR type, not related to XO.

                        • LVMoiSCSI: thick provisioned (not for Dundee IIRC)
                        • NFS: thin pro
                        • Local LVM SR: thick pro

                          Ok so it could potentially be the full size. I just wondered because if you don't have a ton of space you would need to make sure you have enough for the backups to keep those delta drives.

                          Like if you've got 400GB of space and have a 300GB VM that's nearly full, you might not be able to do the delta backup since it needs to keep that extra 300GB drive. Does that sound correct?

                            @johnhooks Sadly yes. That's the usual problem with thick pro storage. That's why NFS is always a good idea for shared SR.

                            I have to make some test to check how Dundee behave now with Local LVM and LVMoiSCSI.

                                    Even VMware recommends NFS when it is available.

                                      @scottalanmiller But wouldn't that effectively build an IPOD?

                                      Even if you have the best possible NFS solution (in reality)?

                                        No, NFS is no more or less unable to be "unIPODed" than any other connection technology. You just build highly reliable storage. We did NFS on SAM-SD HA for a major medical group in Texas over like 30 miles. NFS can be clustered just like anything else.
