I am using restic for backups. I would like to use a non-root user to backup my docker volumes. As the files in the volumes have very different access rights and groups, accessing them is difficult without root rights.
Chowning the files doesn’t help sustainably, as new files are created with a different group again.
What recommendation do you have to smoothly backup files from the docker volumes?

Add the DAC_READ_SEARCH capability to the restic binary (using setcap).This is what allows to read all files. Obviously this means being able to read all, all, files including shadow etc.
