      Bissect is rather fast, it… bissects between 2 commits. If you can pinpoint the exact commit generating that, it means we could probably solve this a LOT faster πŸ™‚

        @olivierlambert Has the problem been confirmed ? I can try to pinpoint where the always-full replications were introduced, but more time efficient to do it on a machine that is fast do replicate, not the one that now takes 2.5 hours (a few minutes for the diff before it borked starting at the backup made 6 Sept)

          No, no confirmation so far, that's why we need more to investigate πŸ™‚

            Great (or maybe not) news.. At least on my system this is very easy to replicate.. On a tiny test machine that only have had a normal backup before, first time doing replication copy (to H2 SSD) it sends it as full as expected. Just did some simple operations on the machine (like apt update, no upgrade), then retried:

              Too bad it becomes that unexplainable slow when it has to fall back to a full backup:

              The first (full) backup was 10x faster:

                @olivierlambert This happens to me too with a459015ca91c159123bb682f16237b4371a312a6.

                I did open an issue https://github.com/vatesfr/xen-orchestra/issues/8969

                andrew64k created this issue in vatesfr/xen-orchestra

                open a459015 causes delta replication to always be full #8969

                    @olivierlambert Correct. Running commit 4944ea902ff19f172b1b86ec96ad989e322bec2c works.

                      @florent so it's like https://github.com/vatesfr/xen-orchestra/commit/a459015ca91c159123bb682f16237b4371a312a6 might introduced a regression?

                        @Andrew then again, with such a precise report, the fix is easier

                        the fix should join master soon
