Check Status of backups

export FTP_PASSWORD="yourFtpPasswordGoesHere"

duplicity collection-status \
  ftp://myBackupUser@192.168.1.x/path/to/backup/folder

For a really large networked backup, this may take a while, because it may need to copy the duplicity-full-signatures.xxx.sigtar.gz file to your local cache. For one of my large backups, this file is 35.58 GB in size which takes a while over a network to retrieve. This file contains, signatures of each file that is backed up so that Duplicity can figure out which part of a file has changed. With that information it can upload only the missing part to complete a new backup set. It may be that increasing the volume size will cause there to be less signatures that need to be stored, thus reducing the size of this file.
