      There's already a thread with this I think. That's a "normal" behavior of XAPI, and we don't think it's a good idea to force plain HTTP when the XAPI returns an HTTPS URL.

      Also, HTTP will disappear in next versions (XCP/XenServer will become HTTPS only), so you should better try the alternative using NBD via this: https://xen-orchestra.com/blog/xen-orchestra-5-76#🚅-faster-backups-preview

        NBD sounds great. I did activate it, but is there any possibility to see, if it is used for a backup`?

          I think @florent added some debug in the xo-server output.

          Did you make some benchs?

              @olivierlambert @KPS You need to activate debug by settings filter='xo:backups:DeltaBackupWriter' in the [logs] part of the config

              don't forget to set useNbd to true in your [backups] config

              if nbd works you will have messages like got nbd connection if there is a nbdError, you will have can't connect to nbd server or no server available

                I added the filter entry and already had "useNbd" in place, and did a restart - but there is nothing about nbd in syslog...
                Can you give me a hint, what I did wrong?

                Using XOCE with xo-server 5.107.4

                  @KPS the nbd part is during the transfer , this part of the log is during the merge

                  there can be a merge before transfer, and another after

                  Is it easy to possible for you to a new branch based on master ? I can make a quik branch with more informations on the nbd state before my holidays

                    Thats strange... There is nothing else in the logs. The first entry after starting the job is the "mount-entry"...

                    I can immediately update, if you want to push this prior to the holiday, but - to be fair: This is currently just a proof of concept for a new installation in 2023 - so - no stress.

                      the message should show if nbd is really activated or not in XO, if there is a nbd enabled network on the host , and if the connection is successfull

                        Hi Florent!
                        I did just install the patch...
                        Updated version 5.107.5 / 5.109.0

                        ...but still nothing in the logs about NBD. I have no idea, what I did wrong.
                        The log does still only contain the information about the merge and the mounts.

                          Please do not invest any time in my debugging. I fist have to really understand, why my changes to config.toml seem to be inactive and I think, i did something wrong.

                          As I will buy XOA soon, this does not matter for the future, but my current testing does only make sense, if I understand the build-process of my XOCE...

                              Just wondering, could NBD also be used in the future for speeding up live migrations with local storage?

                                It's possible we (with XenServer) decide to use NBD everywhere (ie in SMAPIv3 for storage migration, since there's no dedicated format unlike SMAPIv1 and VHD at all stages)

                                  My problem seems to be, that NBD is not getting activated/tried:

                                  Dec 27 09:35:59 XOA xo-server[6477]: 2022-12-27T08:35:59.951Z xo:backups:DeltaBackupWriter INFO use nbd is NOT activated

                                  ...although:

                                  • useNbd = true is set
                                  • Backup-Remote is an SMB-share wir the setting "Store backup as multiple data blocks instead of a whole VHD file. (creates 500-1000 files per backed up TB but allows faster merge) "
                                  • NBD-network is activated on one interface, XO and XCP-ng can work with

                                  Is there any other dependency, that stops NBD from getting used?

                                        Thank you for the update. NBD seems to be used, but there is an error after that, that I do not understand (VDI_IN_USE):

                                        Is this related to NBD in any way?

                                        Thank you and best wishes

                                          @KPS VDI_IN_USE is not NBD related , it may happen but the retry should handle this correctly

                                          thank you for your help

                                            One strange thing: According to the docs, NBD should only be used, when there is a remote storage with "Store backup as multiple data blocks instead of a whole VHD file. (creates 500-1000 files per backed up TB but allows faster merge) "

                                            But: There is also the message "INFO nbd client connected" for storage without that option.
