Unable to exclude files by extension/filetype

[Vish]

Binary package hint: deja-dup

There is no option to *not* backup files with certain filetype/extensions.
It would be useful to set exclusion based on filetypes.
eg: .vdi files; while I could set an exclusion for the .VirtualBox folder, this would just also ignore the VB setup files too. It would be useful to backup the setup files while excluding the massive .vdi.
or. .avi files; usually I download videos to ~/Downloads folder along with other files I download. While I dont require backups of the Downloaded videos, I would like to be able to backup other files that I download to that folder, so setting an exclusion for ~/Downloads folder does not help here.

An option such as "Do not backup files of filetype" is useful when we do not require backups for the filetypes.

I'm not sure why this is considered of low importance: excluding file types is something essential in any backup system. Considering this is the "official" back up solution on Ubuntu, I'd consider changing the priority!

Just can't use this program without this function. I won't backup all .git repos in project folders, but i need to backup .gitignore. Now i must manually add new .git when i clon new repo. Isn't good.

Duplicate of bug 374274, or more precisely a special case. The shell globbing patterns to exclude could be specified as a list of extensions in a text box in Déjà Dup's preferences.
