Duplicati
A free, open-source backup client that securely stores encrypted, incremental, compressed backups on cloud storage services.
In today's digital age, data security and recovery have become paramount. Businesses and individuals alike are increasingly aware of the importance of safeguarding their information from loss or corruption. While traditional methods of data storage and backup have served us well, they often fall short in terms of efficiency, security, and scalability. Enter Duplicati, a powerful open-source backup solution designed to meet these modern demands.
What is Duplicati?
Duplicati is a free, open-source software application that enables users to create encrypted, incremental, and compressed backups of their data. These backups are then stored on cloud storage services such as Amazon S3, Google Cloud Storage, Microsoft Azure Blob Storage, and others. The tool is designed to be both user-friendly and flexible, catering to a wide range of use cases from personal to enterprise-level environments.
Key Features
-
Encryption: Duplicati ensures that all backups are encrypted before being stored in the cloud. This means your data remains secure even if it is intercepted during transmission or storage.
-
Incremental Backups: Instead of creating full backups, Duplicati only copies changes made since the last backup. This significantly reduces storage costs and speeds up the backup process.
-
Compression: The tool supports compression algorithms, further reducing the amount of data stored in the cloud.
-
Cloud Storage Integration: Duplicati works seamlessly with major cloud storage providers, allowing users to choose the most suitable option for their needs.
-
Scheduling: Users can set up automated backup schedules, ensuring that their data is consistently protected without manual intervention.
-
File Retention Policies: Duplicati allows you to define how long backups should be retained before being deleted. This feature is particularly useful for managing storage costs and maintaining only the most recent versions of your data.
How Does Duplicati Work?
Using Duplicati involves a few straightforward steps:
-
Select a Backup Job: You can create multiple backup jobs, each targeting different sets of files or directories.
-
Choose a Storage Location: Decide where you want your backups stored, whether it's on-premises or in the cloud.
-
Configure Encryption Settings: Duplicati provides options for encrypting backups using strong encryption algorithms.
-
Set Up Scheduling: Define when your backups should occur, ensuring that your data is always up-to-date.

For example, you can run a command like:
./duplicati-backup.sh -src:/path/to/source/ -dest:s3://your-bucket/
This command instructs Duplicati to create an incremental backup from the source directory /path/to/source/ and store it in the S3 bucket your-bucket.
