there seems to be a problem with restoring a backup. I installed the last “green” image (2020-04-24-zynthianos-buster-lite-1.0.0.img). I installed my Pianoteq binary (6.7.0) and the License and the latest KIViR.ptq and bells.ptq. I rebootet and updated the presets. Now I restored my data-backup, which I made right before installing the new image. Reboot. Trying to load my simple snapshot of the “CP-80 soundboarded” does not work:

That’s strange because the snapshot were working before…
Just bumping here… noone any idea? There must be a bug in storing or reordering presets in the WebUI, because that was the last thing I have done before this error happens.
That’s really, bad because if I cannot be sure that the preset organization works, I cannot take the Zynthian live on stage.
How can you check the consistency of the snapshots?
I’ve not really used either as I tend to rebuild from scratch. Does anything get loaded at all in the layers, are you starting from a clean zynth? Simple daft questions I know but it does at least set some context.
Clean boot. Trying to load a snaposhot (PT) and while loading (after a few seconds) the screen freezes. I can go “back” and try again: same problem. Some of the snapshots are working. IMHO this is a problem of the consistency of the snapshots itself…
BTW: Uploaded the system backup and after that the data-backup. Reboot. Now NOTHING works anymore. Black screen.
Has anyone tried the restore functions or am I the first?
Old threat but I think I have a similar problem. I had to re-flash my zynthian today. After that, I wanted to restore my data. I had secured everything before. After restoring, the snapshots do not work. I couldn’t even see them. I then imported them via webconf. Then I could see and select them again. Unfortunately, all sequencer data is no longer there. @riban Am I doing something wrong?
We aspire to backwards compatibility but sometimes fall short. We have learned from experiences like this thread described and great ias thoroughly as we can to reduce the risk of old snapshots failing to load in new versions of the software. It was certainly tested a lot during the 2210 release. What version were your snapshots saved in and what version are you running now? Have you updated since flashing the image?
