Rclone and OCI S3 Interface

March 29, 2018 admin

I am testing rclone to the Oracle Cloud Interface object storage and recording what worked for me.

Note I could not get the swift interface to work with rclone, duplicity or swiftclient yet. Although straightforward curl does work to the swift interface.

rclone configuration generated with rclone config

# cat /root/.config/rclone/rclone.conf
[s3_backups]
type = s3
env_auth = false
access_key_id = ocid1.credential.oc1..a<redacted>ta
secret_access_key = K<redacted>6s=
region = us-ashburn-1
endpoint = <tenancy>.compat.objectstorage.us-ashburn-1.oraclecloud.com
location_constraint = 
acl = private
server_side_encryption = 
storage_class =

Issue with max-keys. This problem although very difficult to find was also preventing copy/sync of folders although a single file was working. rclone v1.36 was installed form Ubuntu repos and issue resolved with newer version.

# rclone ls s3_backups:repo1
2018/03/29 08:55:44 Failed to ls: InvalidArgument: The 'max-keys' parameter must be between 1 and 1000 (it was 1024) status code: 400, request id: fa704a55-44a8-1146-1b62-688df0366f63

Update and try again.

# curl https://rclone.org/install.sh | sudo bash

Rclone: Rsync for Cloud Storage

In a future article I will add my testing around BorgBackup + rclone + OCI objectstorage from this interesting idea: https://opensource.com/article/17/10/backing-your-machines-borg
