i have setup Urbackup server on Ubuntu and when i try to change the “Backup Storage Path” to different internal hard drive (ex: /media/disk1) i got error message “The directory where UrBackup will save backups is inaccessible. Please fix that by modifying this folder in ‘Settings’ or by giving UrBackup rights to access this directory.(err_folder_not_found)”
You will have to check what user/group urbackup runs as. The you will have to give a read write permission to that user on the folder. Actually it might not be wise to use the path you wrote, most probably that is a location you see the raw device, you should mount the drive to a folder in your file structure, like /backupmedia
you can google how to check the user a service runs under in linux, and how to mount the disk to a folder. ALso check how to change rights and ownership if you must.
