Re: [Duplicity-talk] How to run duplicity with a Cron Job

[Peter Spikings]

duplicity reads the passpharse from the PASSPHRASE env variable and only
asks for it when that variable is unset. Modify your cron job as follows:

PASSPHRASE=whatever duplicity --encrypt-key 223221E2 --sign-key 56833F9B
/etc file:///tmp/backup
