  • Access Key: FEO2c60fbb123a7c263cc53751d

  • Secret Key: KhnddL-AA8DpYRG8o_nlnsdngPosi5KfsaoSEdA1s9k

  • Region: Frankfurt-de-fra-1

  • S3 Endpoint: sos-de-fra-1.exo.io

  • host_bucket: %(bucket)s.sos-de-fra-1.exo.io

Next, run the following command to configure S3cmd tool:

s3cmd --configure

You will be asked to provide your Exoscale Access Key, Secret Key, Region, and Endpoint as shown below:

Enter new values or accept defaults in brackets with Enter.
Refer to user manual for detailed description of all options.
 
Access key and Secret key are your identifiers for Amazon S3. Leave them empty for using the env variables.
Access Key: FEO2c60fbb123a7c263cc53751d
Secret Key: KhnddL-AA8DpYRG8o_nlnsdngPosi5KfsaoSEdA1s9k
Default Region [US]: Frankfurt-de-fra-1
 
Use "s3.amazonaws.com" for S3 Endpoint and not modify it to the target Amazon S3.
S3 Endpoint [s3.amazonaws.com]: sos-de-fra-1.exo.io
 
Use "%(bucket)s.s3.amazonaws.com" to the target Amazon S3. "%(bucket)s" and "%(location)s" vars can be used
if the target S3 system supports dns based buckets.
DNS-style bucket+hostname:port template for accessing a bucket [%(bucket)s.s3.amazonaws.com]: %(bucket)s.sos-de-fra-1.exo.io
 
Encryption password is used to protect your files from reading
by unauthorized persons while in transfer to S3
Encryption password:
Path to GPG program:
 
When using secure HTTPS protocol all communication with Amazon S3
servers is protected from 3rd party eavesdropping. This method is
slower than plain HTTP, and can only be proxied with Python 2.7 or newer
Use HTTPS protocol [Yes]:
 
On some networks all internet access must go through a HTTP proxy.
Try setting it here if you can't connect to S3 directly
HTTP Proxy server name:
 
New settings:

Secret Key: KhnddL-AA8DpYRG8o_nlnsdngPosi5KfsaoSEdA1s9k
Default Region: Frankfurt-de-fra-1
S3 Endpoint: sos-de-fra-1.exo.io
DNS-style bucket+hostname:port template for accessing a bucket: %(bucket)s.sos-de-fra-1.exo.io
Encryption password:
Path to GPG program: None
Use HTTPS protocol: True
HTTP Proxy server name:
HTTP Proxy server port: 0
 
Test access with supplied credentials? [Y/n] Y
Please wait, attempting to list all buckets...
Success. Your access key and secret key worked fine :-)
 
Now verifying that encryption works...
Not configured. Never mind.
 
Save settings? [y/N] y
Configuration saved to '/root/.s3cfg'

You can now verify your bucket information using the following command:

s3cmd info s3://file-exoscale/

You will get the following output:

s3://file-exoscale/ (bucket):
Location: de-fra-1
Payer: BucketOwner
Expiration Rule: none
Policy: none
CORS: <?xml version="1.0" encoding="UTF-8"?><CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/"></CORSConfiguration>
ACL: snapshooter: FULL_CONTROL

Use S3cmd to Backup Files to Exoscale Bucket

S3cmd is now installed and configured to manage the Exoscale bucket.

Next, log in to the server where your file server is hosted.

Once you are log in, compress the /var/log directory and copy it to the Exoscale bucket using the following command:

tar -czvf - /var/log | s3cmd put - s3://file-exoscale/log_backup.tar.gz

You will get the following output:

upload: '<stdin>' -> 's3://file-exoscale/log_backup.tar.gz' [part 1 of -, 218KB] [1 of 1]
224132 of 224132 100% in 0s 383.21 KB/s done

You can now verify your Bucket using the following command:

s3cmd ls s3://file-exoscale

You should see your uploaded backup files in the following output:

2022-07-28 06:10 224132 s3://file-exoscale/log_backup.tar.gz
