+++ title = "Initialize Repositories" weight = 40 +++ Your backup repositories need to be initialized before they can be used. Norg has a command to do this for you once you. To initialize your repositories one by one, you can run the following command: ```sh norg -c myconfig.toml init -e repokey-blake2 ``` This will initialize a Borg repository using the `repokey-blake2` encryption algorithm, making it ready for use. Restic does not use the same encryption algorithm option, so the above command may fail. However, running the below command again, without the `-e repokey-blake2` option will initialize a Restic repository correctly, leaving the borg repository untouched. **TODO**: We plan to resolve the requirement of running this command twice in the future.
