Dockerized duplicity backup tool.

Usage

Backup to Google Cloud Storage example

WORK IN PROGRESS

Google Cloud Storage nearline costs about $0.01/GB/Month.

Set up:

1. Sign up, create an empty project, enable billing, and create a bucket
2. Under "Storage" section > "Interoperability" tab > click "Enable interoperable access" and then "Create a new key" button and note both Access Key and Secret (alternatively use gcloud's gsutil config -a to generate the ~/.boto configuration file and mount it as /home/duplicity/.boto).

Now you're ready to perform a backup:

$ docker run --rm --user $UID -v /:/data:ro -e PASSPHRASE=P4ssw0rd -e GS_ACCESS_KEY=MYGOOGLEACCESSKEY -e GS_SECRET_ACCESS_KEY=SomeVeryLongAccessKey duplicity duplicity /data gs://my-bucket-name/some_dir

To restore, you'll need:

• Keep keys or regenerate them to access your Google Cloud Storage.
• The PASSPHRASE you've used.

TODO see note on Google Cloud Storage.

Backup to Google Drive example

Google Drive offers 15GB for free.

Set up:

1. Follow notes on Pydrive Backend to generate a P12 credential file (call it pydriveprivatekey.p12) and note also the associated service account email generated (e.g. duplicity@developer.gserviceaccount.com).

2. Convert P12 to PEM:

   $ docker run --rm -i --user $UID -v $PWD/pydriveprivatekey.p12:/pydriveprivatekey.p12:ro wernight/duplicity openssl pkcs12 -in /pydriveprivatekey.p12 -nodes -nocerts > pydriveprivatekey.pem
   Enter Import Password: notasecret
   

Now you're ready to perform a backup:

$ docker run --rm --user $UID -v /:/data:ro -e PASSPHRASE=P4ssw0rd -e GOOGLE_DRIVE_ACCOUNT_KEY=$(cat pydriveprivatekey.pem) duplicity duplicity /data pydrive://duplicity@developer.gserviceaccount.com/some_dir

To restore, you'll need:

• Regenerate a PEM file (or keep it somewhere).
• The PASSPHRASE you've used.
