Repository backends

S3 storage

To create a repository stored on an S3-compatible server, create an INI file (name it how you want) with the following configuration:

[Repository]
URL = https://<endpoint>/<bucket>

[S3]
AccessKeyID = <AWS access key ID>
SecretKey = <AWS secret key>

To help you form a valid URL, here are a few examples for common S3 providers:

Provider URL Conditional writes
Amazon S3 (virtual-host style) https://<bucket>.s3.<region>.amazonaws.com Yes
Amazon S3 (path style) https://s3.<region>.amazonaws.com/<bucket> Yes
Backblaze B2 https://s3.<region>.backblazeb2.com/<bucket> No
Cloudflare R2 https://<userid>.r2.cloudflarestorage.com/<bucket> Yes
Exoscale Object Storage https://sos-<region>.exo.io/<bucket> Yes
Scaleway Object Storage https://<bucket>.s3.<region>.scw.cloud Yes

Rekkord may issue ListObjects API calls to reduce blob overwrites on hosts without conditional write support, which may incur additional cost.

It is recommended to use a provider with support for conditional writes!

You can omit the SecretKey value, in which case a prompt will ask you the access key.

Once this is done, use rekkord init -C config.ini to create the repository.

SFTP server

To create a repository stored on an SFTP host, create an INI file (name it how you want) with the following configuration:

[Repository]
URL = <user>@<host>:/path/to/repository

[SFTP]
Password = <SSH password>
KeyFile = <SSH keyfile>

Use either a password or a key file. If you omit both, a prompt will ask you for a password.

Just like with ssh, you will need to validate the host fingerprint the first time you connect to it. However, you can instead directly provide the correct host fingerprint as the Fingerprint to avoid this, as shown in the example below:

[Repository]
URL = foo@example.com:/backup

[SFTP]
KeyFile = /home/bar/.ssh/id_ed25519
Fingerprint = SHA256:Y9pmJfkaok8t0dFJrfi8/LLUNhOYwAZGHUNGsYAiJUM

Once this is done, use rekkord -C config.ini init to create the repository.

Local filesystem

To create a repository in a local directory, create an INI file (name it how you want) with the following configuration:

[Repository]
URL = /path/to/repository

Once this is done, use rekkord -C config.ini init to create the repository.
