Does this computer have multiple user logins (that you want to back-up), or is it primarily used by one user?<\/p><\/blockquote>\n\n\n\n
This is important because you can install Duplicati in one of two ways: to run as a single-user, or to run as a system service that is available to all users. By default Duplicati is installed for a single user, but if there is more than one user on the computer you want to be able to back-up, you’ll want to install it as a service.<\/p>\n\n\n\n
If you don’t install it as a service, when Duplicati tries to read files that belong to the other users, it will get a permission denied error and won’t be able to back those files up. You don’t want to find out that your files weren’t backed up when it’s too late.<\/p>\n\n\n\n\n\n\n\n
I’ve provided some MacOS specific configurations in that section for setting it up as a service.<\/p>\n\n\n\n
RaspberryPi<\/h2>\n\n\n\nInstall Duplicati on a RasperryPi<\/h3>\n\n\n\n
To get Duplicati successfully installed on a RaspberryPi running Raspbian, you’ll likely have to also install some of the mono dependencies to avoid installation errors<\/a>.<\/p>\n\n\n\n Follow the Raspbian 9 installation instructions on the mono-project site<\/a>. No need to `sudo apt-get install mono-devel` – the dependencies for Duplicati will get automatically resolved.<\/p>\n\n\n\n Once that’s done you can (re)install Duplicati, hopefully without errors.<\/p>\n\n\n\n For my MacOS installation I needed to install it as a service. It’s my wife’s Macbook. I also use it for Fusion360<\/a>, and I like my scroll settings different than she does. So it has two user accounts, both with files we want to back-up. Installing Duplicati as a service in this case is a must.<\/p>\n\n\n\n Both of the plist configuration files can be installed as any user as they’ll be going in a system-wide location which will run Duplicati as a system service.<\/p>\n\n\n\n Once those two files are in place, the next time you reboot and log in, any and all users should have a Duplicati icon in the system tray. You can then configure a backup job<\/a> to read all users’ files without issue.<\/p>\n\n\n\n There are two settings to reduce Duplicati’s resource usage:<\/p>\n\n\n\n On my brand-new 2019 XPS13 developer system Duplicati was using 280% CPU.<\/p>\n\n\n\n In other words, three of the 8 available cores were dedicated to Duplicati, plus disk I\/O. I recommend setting As always, test your configuration. I like to do a daily backup with “Smart backup retention” so my backup cloud disk usage doesn’t grow indeterminately.<\/p>\n\n\n\n Make sure your RaspberryPi backups are completing. It will take a while<\/em> if you have a lot of data. For a 1TB backup from my RaspberryPi, it took a full week to complete because it is s-l-o-w. Once a full backup is made, the incremental updates shouldn’t take as long, but they may still take longer than a day to complete.<\/p>\n Single-user vs service Before you install Duplicati, there’s one question you need to ask: Does this computer have multiple user logins (that you want to back-up), or is it primarily used by one user? This is important because you can install Duplicati in one of two ways: to run as a single-user, or to run… Continue reading MacOS<\/h2>\n\n\n\n
