wget -O restic.bz2

bunzip2 restic.bz2

chmod +x restic

mv restic /usr/bin/

Verify restic install

$ restic version
restic 0.12.0 compiled with go1.15.8 on linux/amd64

Backup setup

Create an encryption key

You must first create an encryption key that will be used encrypt your data in our infrastructure. Please note that this encryption key can't be changed and in the event of its loss your data will no longer be readable.


To generate a strong key you can use the command $ openssl rand -base64 14

You must store this key in a single text file so that it can be read by restic when using it. For example:

$ echo <My-password> > /path/to/your/file/containing_the_key

Create the Restic configuration file:

Based on the credentials you received after the creation of your SwissBackup account, create for example the file /home/user/restic_credentials with the following content, replace the different variables accordingly to your credentials.

export OS_AUTH_URL=
export OS_REGION_NAME=RegionOne
export OS_PROJECT_NAME=sb_project_SBI-XXXX
export OS_PASSWORD=<SwissBackup password>
export OS_USER_DOMAIN_NAME=default
export RESTIC_REPOSITORY=swift:sb_project_SBI-XXXX:/<bucket name>
export RESTIC_PASSWORD_FILE=</path/to/your/file/containing_the_key>


OS_AUTH_URL: Url to access the SwissBackup cluster. or

OS_PROJECT_NAME: SBI-XXX is your SwissBackup username provided by mail and on your manager

RESTIC_REPOSITORY: Bucket name is container in swift used to store data. Bucket name could be My_VM_name for example.

Source the restic configuration file

You can now load your credentials and initialize your directory to perform your first backup

source /home/user/restic_credentials

Initialise the repository

restic -r swift:sb_project_SBI-XXXX:/<bucket name> init

Launch your first backup in SwissBackup !

restic backup /path/to/folder/to/backup
