Duplicity

Exclude subfolders in included directories with exclude globbing filelist

Asked by Martin Abbrent

I'm using Duply [1] as simple frontend for Duplicity but this forces me to use an exclude globbing filelist to specify which files I want to backup. Now I want to exclude a subfolder of an included directory but it is getting backed up every time I start it. I force full backups for testing.

This is my exclude file list:

+ /etc
+ /root
+ /var
+ /home
- /root/.cache
- /var/cache
- /var/lib/dpkg
- /var/lib/apt
- **

I also tried to add slashes and double "*" to the excluded ones. Duply runs the following command:

duplicity full --name 'duply_myname' --encrypt-key # --sign-key # --verbosity '4' --gpg-options '--compress-algo=bzip2 --bzip2-compress-level=9' --full-if-older-than 1M --volsize 100 --exclude-globbing-filelist /etc/duply/myname/exclude / s3://amazon-desitination/dir

Does anybody see the mistake?

Thank you,
Martin

yes. ex/inclusions are checked from top to bottom for each path. there is a detailed description on the duplicity manpage
 http://duplicity.nongnu.org/duplicity.1.html#sect10

long story short. order the list by path depths descending, long first, so that a deeper folder is not masked by a more generic parent folder definition.

Thank you edso, changing the order solved my problem. My exclude file list now looks like this:

- /root/.cache
- /var/cache
- /var/lib/dpkg
- /var/lib/apt
+ /etc
+ /root
+ /var
+ /home

I've read the man page but I didn't got it.
