Method of using s3cmd to synchronize files to digitalocean object storage spaces

🕓 by admin





S3cmd is a free command-line tool and client for uploading, retrieving, and managing data in Amazon S3 and other cloud storage service providers that use the S3 protocol (such as Google Cloud Storage or DreamHost DreamObjects). It is most suitable for advanced users who are familiar with command line programs. It is also ideal for batch scripts and automatic backup to S3 (triggered by cron etc.). S3cmd is written in Python. It is an open source project provided under the GNU Public License v2 (GPLv2), and is free for commercial and private use. You only pay for Amazon ’s use of its storage. Since its first release in 2008, S3cmd has added many features and options. We recently counted more than 60 command-line options, including multipart upload, encryption, incremental backup, s3 sync, ACL and metadata management, S3 bucket size, bucket strategy, etc.! Here is how to use s3cmd to synchronize files to digitalocean object storage spaces Install s3cmd.

apt-get install s3cmd // debian / ubutnu
yum install s3cmd // centos / fedora
// It is not recommended to install s3cmd using the above method, because the installed s3cmd version is too low
// It is recommended to use the following method to install, or enter the s3cmd download program to install it yourself
// install pip
yum install python-pip // centos
apt-get install python-pip // debian / ubuntu
apt-get install python-setuptools
// Install s3cmd
pip install s3cmd
First, we must create an API for digitalocean object storage spaces,

https://cloud.digitalocean.com/account/api

Configure s3cmd synchronization file to digitalocean object storage spaces You can use the s3cmd --configure command to enter the interactive configuration s3cmd But to make it easier to configure s3cmd sync files to digitalocean object storage spaces Write directly to the s3cmd configuration file here ,,, the following is the code, with comments, easy to understand and configure Create a .s3cfg file and write the following code
