I setup Ubuntu backup functionality to backup my home directory. It takes full backup in a month period. Is there a possibility to change frequency of full backups? I want to setup duplicity to create only seven incremental backup and next it will be full backup. Where I can change it?

Yeay! I found it! :D First install dconf-editor:

sudo apt-get install dconf-editor

Second run dconf-editor. In path /org/gnome/deja-dup/ is a key full-backup-period. Default is 90 days - every 90 days full backup is running. Changing that value is changing full backup frequency.

As the usage page suggests, if you run:

duplicity /some/dir sftp://[email protected]/some_dir

repeatedly, first it will be a full backup then all subsequent runs will be incremental. You can force it to do full backup after a particular time using the --full-if-older-than <time> parameter. So,

duplicity --full-if-older-than 1M /some/dir sftp://[email protected]/some_dir

will do a full backup every month. So you can set the first command to run for seven times and then do a full using the second command.

  • I ask for setup duplicity service in Ubuntu that is runned everyday, not for command options . I setup backup of my home in Ubuntu settings but it takes full backup once per month (or something). I want to shorten that period to one week.

  • How did you set it up in the first place? Are you already running a cron job?

  • Like I'm say before, I'm using Ubuntu settings to setup backup. image.qkiz.pl/di/6120/Kopie_zapasowe_006.png
