Duply (simple duplicity)
duply is a frontend for the mighty duplicity magic. duplicity is a python based shell application that makes encrypted incremental backups on remote storages. Several backends like ftp, sftp, imap and others are supported.
duply simplifies running duplicity with cron or on command line by:
- keeping recurring settings in profiles per backup job
- enabling batch operations eg. backup_verify_purge
- executing pre/post scripts
- precondition checking for flawless duplicity operation
Since version 1.5.0 all duplicity backends are supported. Hence the name changed from ftplicity to duply.
History (from ftplicity to duply)
In 2006 the german computer magazine c't released the tool ftplicity under GPL2. It was a convenience shell front end for encrypted ftp backups with the python based backup tool duplicity. Shortly after major changes in duplicity broke the software and several parties released fixes on their private websites. duply still called ftplicity started out as one of them.
The latest version of c't ftplicity 1.2 (21.10.2009) can be found on heise.de.
But soon further functionality found it's way into the patch and because the maintenance of the original author was sparsely the project ftplicity on sourceforge was created. The idea was to spread the word and find contributors in order to maintain and enhance ftplicity further.
Since then ftplicity underwent further improvement until in version 1.5 the limitation to the file transfer protocol as only backend was removed. Because of this the project was renamed to a more generic name (not advertising ftp). duply (simple duplicity) was born.
