Hi both, thanks for the respons and info.
Already at place and used:
- official kodi backup Addon.
- Win32diskimager as SD image writer/reader(backup).
(learned the hard way make a extra backup when you are done finalizing the library.)(cost me a day rearanging input to my liking)
- The LibreELEC's back in TAR local folder on SD in "backup"and then replaced to my pc.(space saving)
The USB Sdcard Backup wizzard looks exactly what i ment. a list of things i could backup separate.
indigo i can't run, i haven't kodi v18 yet. (hardware Cuboxi so some trouble in upgrading)
LibreELEC's internal Backup/Restore tool has never included system files, only the most part of the /storage partition.
ok, maybe the addon's data/settings then. Why i thought it's back up also system things was i had a issue that after watching a video and i hit "stop" the screen turns black as in "empty" and stays that way. it doesn't return to the skin view of selection mode. only way to solve that is kill power. this is in effect watch a video and turn off power wait few minuts to reboot before you can watch a second.
(this effect becan after a long pauze moment which i stopt by hitting play and stop in a row causing the system to freeze. => power off to reboot. after that i had this problem.)
the official kodi backup did bring this problem back on my working image so that's why i thought it stores also "systemdata ".
Ended up rebuilding my stored sd image back to present state. (need to backup NOW!) before installing other addons.
Wat's stored in the TAR? (LibreELEC's backup addon) and i tried to load a v17.6 backup in a v19 nightly build which din't work.
So how can i transfer my personal data to a next version if there is a stable one for a imx6 cuboxi4pro? Use the backup to speed up a new build.
Which is my next question, where can i find changelog info of nightly builds, what's repaired so to speak. So i can read if my problem which i have in video encoding and a not working optical spdiff sound issue when i use a nightly build for cubox.(didn't try the last one but the three before had all the same issue).
