Acrosync: Duplicacy for Mac, Free DeDupe Cloud Backup Tool

Acrosync LLC announced the availability of Duplicacy 1.0, their next-generation cross-platform cloud backup tool for Mac OS X.

Duplicacy is based on the principal of lock-free deduplication, which allows multiple clients to backup their data to the same storage destination simultaneously, to achieve cross-computer deduplication, without the need for any file locks, thus making it readily work with various cloud storage services.

Thanks to its lock-free deduplication method, Duplicacy allows users to backup their data to most popular cloud storage services without losing access to the essential features that are expected of a state-of-the-art backup tool. The app also supports backup to local disks and SFTP servers, making it easy to backup user data to Mac or Linux computers, or NAS boxes.

The app also offers an elegant GUI which makes it easy to quickly setup and execute any backup process, be it to a remote cloud server, or to local storage. Using the simple to follow GUI, backups can be set to create full snapshots of the data, each of which is in fact an incremental backup in the sense that only files that have been changed since the last backup will be transferred. Backups can be scheduled to automatically run at frequencies from every half an hour up to once a week, depending on the customer’s backup requirements. Duplicacy can also be set to send an email after the completion of every backup.

“Duplicacy offers users the flexibility to backup their Mac or Windows computers to almost any available form of storage, be it local, cloud-based, or even their own SFTP server or NAS boxes,” says Gilbert Chen, owner, Acrosync. “We believe Duplicity is a complete backup solution that will meet the needs of every user, whether they’re a personal user who just wants to make sure their single Mac is securely backed up, or the corporate user who has hundreds of Macs or PCs that need to be backed up in a reliable manner.“

Features:

• Incremental backup: backups only the data that has changed since the last backup

• Full snapshot: While each backup is incremental, it behaves like a full backup for easy restore and deletion

• Deduplication: Identical files are stored as one copy, and identical parts from different files are stored as one copy

• Encryption: Encrypts not only file contents but also information such as file paths, sizes, times, and more

• Deletion: Every backup can be deleted independently without affecting other backups

• Concurrent access: Multiple clients can backup to the same storage simultaneously

• Snapshot migration: All or selected snapshots can be migrated from one storage location to another

Duplicacy currently supports a number of popular cloud storage services, including Amazon S3, Google Cloud Storage, Microsoft Azure, Dropbox, and Backblaze. It also supports backup to local disk drives, SFTP servers, and NAS boxes.

In addition to using the handy GUI for operating Duplicacy, users can also invoke the backup engine from the command line, offering the flexibility to run the solution from custom scripts. A number of features, such as adding additional storage, copying backups from one storage to another, and changing encryption passwords, are only available in the command line version.

Duplicacy commercial users also gain access to the source code for the app at no additional charge. Source code access allows users to gain a better understanding of how Duplicacy works, and can be secure in the knowledge that important backups will always be kept safe and will never fail. Users can also customize the powerful Duplicacy source code, to add new features they require in order to match their own unique backup needs.
