If I may add to that, the rules defined in a .kopiaignore
file are relative to the folder where that file lives. Hence, we can use more than one.
For example, I have ~/.kopiaignore
that ignores .Trash/
(who would want to back up garbage?).
I have ~/Library/.kopiaignore
that ignores .Cache/
(among other things)
Then I also have ~/Downloads/.kopiaignore
that contains
*.app
*.bz2
*.dmg
*.gz
*.tar
*.zip
as those are all downloadable content that I don’t need to back up.
But I don’t want to ignore those file types from everywhere in my $HOME.
Hope that helps.
