Backing up multiple directories to S3 with Duplicity

We recently setup a new dev server and configured it backup to S3 using Duplicity using kappataumu’s helpful article Cloud backups with Duplicity and Amazon S3.

In our case we wanted to backup a handful of specific directories on a regular basis (the rest of the server is backed up via a weekly snapshot). However, the script shown in the article was for only one directory.

Here’s a slight modification to the script that provides a way to backup multiple directories using Duplicity by using a bash function:

duplicity_backup(){
SRC_PATH=$1
DEST_PATH=$2
duplicity \
 --verbosity notice \
 --s3-use-new-style \
 --encrypt-key="$GPG_KEY" \
 --sign-key="$GPG_KEY" \
 --full-if-older-than 7D \
 --asynchronous-upload \
 --volsize=100 \
 --log-file "$HOME/.duplicity/notice.log" \
 "$SRC_PATH" \
 s3+http://$S3_BUCKET/$DEST_PATH
}
duplicity_backup "/path/to/first/source" source_one
duplicity_backup "/path/to/second/source" source_two
