I had erased my local Python libraries but reinstalled. Also I extracted the passphrase into a second script that I include via source now. Somehow an upload failed and I. Duplicity uses the rsync algorithm so only the changed parts of files are sent to the archive when doing an incremental backup. For instance, if a long log file increases by just a few lines of text, a small diff will be sent to and saved in the archive. Standard file format. Choice of remote protocol: Local storage. Duplicity incrementally backs up files and directory by encrypting tar-format volumes with GnuPG and uploading them to a remote (or local) file server. To transmit data it can use ssh/scp, local file access, rsync, ftp, and Amazon S3.

Configure B2 Storage in the Command Line Version
To use the Backblaze B2 storage with the command line version of Duplicacy, enter a storage url in the format of b2://bucket, where bucket is the name of the bucket to be used.
You will then be prompted for entering the account id and application key. On Windows and macOS, these credentials will be saved in an encrypted password vault provided by the OS and retrieved later when needed. On Linux, if such a password vault is not available, you can store them in two environment variables, DUPLICACY_B2_ID and DUPLICACY_B2_KEY, in order to avoid typing in them ever time.
