Hi @hannesmenzel ,
I had the same problem as you. What I have done is move zynthian-my-data completely to USB drive (It’s a very small drive, you hardly see it):
-
I copied everything from
zynthian-my-datato my USB drive, including directory structure. -
Then I created a softlink for zynthian-my-data to the USB drive:
cd /zynthian
mv zynthian-my-data/ zynthian-my-data-OLD/
ln -s "/media/root/ZYNTHIAN" "/zynthian/zynthian-my-data"
where my USB drive is labelled “ZYNTHIAN”
Now I can simply make a backup from my USB drive to a second one. I do this on my Windows machine with robocopy. Takes only a few seconds when there are just a few changes.
Only pitfall:
When the USB drive is removed, Zynthian does not start. You get a sad Daphne Oram picture with a SegFault(1) and ERROR in red.
This is caused by Zynthian not finding it’s last snapshot.
(No such file or directory: '/zynthian/zynthian-my-data/snapshots')
For the rest everything works as normal and just as fast as on SD card.
Kind regards,
Hans.
