How can i achieve that my main remote is exported to bunch of WORM disk? I tried making special remote directories for each of them on loopback device, but when exporting data it fail. And export the same files to each remote, rather than files not archived.

What i did

• Create git annex repo, then imported pictures from special remote directory, and merged it to main branch

git annex initremote main-pictures type=directory directory=../Pictures/ encryption=none importtree=yes exporttree=yes
git annex import --from main-pictures master --no-content
git annex merge --allow-unrelated-histories main-pictures/master

this step was done so i don't have symlinks on my current folder structures

• I created 3 repositories as such on which i want to export data

git annex initremote BD2 type=directory directory=/run/media/tokariew/BD2/ exporttree=yes encryption=none
git annex wanted BD2 standard
git annex group BD2 archive

• Then i tried to export to all 3 remotes data

 git annex export  master -t BD2 -f main-pictures

Each fail after copying ~25GB (size of loopback)

(recording state in git...)
export: 28555 failed

• I was thinking that this is ok, and with export to next device it will export files which are not in previous remotes.

What should i do to archive my pictures and have single copy on BD/dvd?
