btrfs sub snap foo bar creates an exact same contents of subvolume
foo as subvolume
bar, except the subvolumes in
What I want is excluding some regular folders too from the output (
bar), such as
tmp; just like
rsync --exclude ... does.
There are several ways to make this happen, for example:
- Create a subvolume for the each folder that is to be excluded. (Con: automatically generated folders can not be excluded as they are created as regular folders, such as
node_modulesin this scenario)
- Create a temporary subvolume, delete the unwanted files/folders (Most promising approach), then create the final subvolume from it.
Other than above, can we apply a programmatic filter while creating snapshots?
