I am new to this Ubuntu thing and I am having troubles figuring out how to copy the backup directory to the second drive in my System76 Meerkat server. I attempted to use the Files app; tried dragging the 'home/user-data/backup/encrypted/ directory over to the newly created directory “archive_20200428”. No go. Complained that "error while copying “duplicity-******.sigtar.ggg. Permission Denied”. It makes the same complaint for every file in the encrypted directory.
Would someone be willing to hold my hand a bit by giving me more specific instructions rather than the simple ‘backup to second drive’?
