How to back up with Duplicati to Exoscale Object Storage
Duplicati is easy to use. This step by step guide will help you to get started quickly.
Duplicati was designed for online backups from scratch and is not only data efficient but also handles network issues nicely. The backup client allows to resume interrupted backups and regularly tests the content of backups. This allows an early detection of broken backups on corrupt storage systems.
A graphical user interface with a wizard-style interface as well as a command-line version for usage in headless environments is provided by Duplicati. Both interfaces use the same core and thus have the same set of features and capabilities.
The service is compatible with Linux as well as Windows.
Linux / Ubuntu
- Create an Exoscale SOS Bucket to store your backups
- Create an IAM Key to have access to your Exoscale SOS Bucket
- Install the needed packages on Ubuntu (see the Duplicati documentation for details)
For this guide we use the following commands:
wget https://updates.duplicati.com/beta/duplicati_220.127.116.11-1_all.deb apt install ./duplicati_18.104.22.168-1_all.deb
Change /etc/default/duplicati to add webservice part, please restrict access to it over security group settings
root@vm2backup:~# cat /etc/default/duplicati # Defaults for duplicati initscript # sourced by /etc/init.d/duplicati # installed at /etc/default/duplicati by the maintainer scripts # # This is a POSIX shell fragment # # Additional options that are passed to the Daemon. DAEMON_OPTS="--webservice-interface=any --webservice-port=8200 --portable-mode"
Enable and start Duplicati service afterwards
root@vm2backup:~# vi /etc/default/duplicati root@vm2backup:~# systemctl enable duplicati.service Created symlink /etc/systemd/system/multi-user.target.wants/duplicati.service → /lib/systemd/system/duplicati.service. root@vm2backup:~# systemctl daemon-reload root@vm2backup:~# systemctl start duplicati.service root@vm2backup:~# systemctl status duplicati.service duplicati.service - Duplicati web-server Loaded: loaded (/lib/systemd/system/duplicati.service; enabled; vendor preset: enabled) Active: active (running) since Wed 2022-06-01 10:46:52 UTC; 4s ago Main PID: 14187 (mono) Tasks: 16 (limit: 4672) Memory: 33.3M CGroup: /system.slice/duplicati.service ├─14187 DuplicatiServer /usr/lib/duplicati/Duplicati.Server.exe --webservice-interface=any --webservice-port=8200 --portable-mode └─14207 /usr/bin/mono-sgen /usr/lib/duplicati/Duplicati.Server.exe --webservice-interface=any --webservice-port=8200 --portable-mode Jun 01 10:46:52 vm2backup systemd: Started Duplicati web-server.
- Connect to the webinterface of Duplicati to configure your backup
Change to S3 for destination
In this example we are using a bucket in BG-SOF-1 to store our backups
If you run backups from multiple instances to the same bucket, please create separate folder for each instance (e.g.: vmbackup/”instancename”)
Select folders and files which you want to backup
Define a schedule
Choose your retention
Confirm storing of passphrase
Click “Run now” to start the backup immediately
Duplicati starts the backup to your bucket
Restore files from the backup
Choose restore source
Select files to restore
Set restore options
Check restore on vm2backup
