Option to stay on one file system


#1

It would be very useful to have the option -one-file-system, which shall prevent the backup process from copying files and folders from another file system. It’s a quite popular option among other tools :slight_smile:


#2

What other tools is this popular in? How is the utility supposed to tell which filesystem to include files from?


#3

E.g. Borgbackup, rsync or tar. The filesystem where the root of the repository is used and if a subdirectory is in another FS, then that boundary is not crossed. An exception would be, that a subdir would explicitly be specified to be backed up.
