It works pretty well, though there is no image backup capability.

Thanks!

I notice that there are two formats:
Linux (NBF) (BETA)
Linux (legacy backup format)

Concerning Linux distributions, Ubuntu, among other, is listed. Can anyone tell me if Mint is supported as I understand it is a derivative of Ubuntu.

Hi !
Yes, Linux Mint is based on Ubuntu/Debian
For Linux Mint, you should use the Ubuntu .deb package, as it is fully compatible and works the same way as on Ubuntu.

Thanks! Will give it a go.

What about these options, which do you recommend?
Linux (NBF) (BETA)
Linux (legacy backup format)

The choice of backup format depends on what exactly you want to back up and which features are important for your use case. The difference is not only in maturity, but in architecture and available capabilities.

Linux (legacy backup format) is the classic file-level backup engine:

- Standard incremental backups
- Compression and encryption
- File filters and retention policies
- Stable and predictable behavior for typical file backup scenarios

Linux (NBF) is the new storage architecture that introduces several technical improvements:

- Client-Side Deduplication
- Consistency Checks
- Restore on Restore Points
- Optimized operations with storage, resulting in fewer requests, faster synchronization, and faster purge
- Continued data upload in case of network issues
- Object size up to 256TB to any storage destination
- Optimized performance and storage usage for a large number of small files
- Improved incremental backup performance.

In short, Legacy provides a traditional file backup approach with standard functionality, while NBF offers a more modern data format focused on storage efficiency, integrity, and scalability.

If you need features like deduplication, consistency checks, and better handling of large datasets, NBF is the better choice.
If you only require a classic file backup with familiar behavior, Legacy will work as expected.

Thonny. Thank you for the very helpful description. Any idea when the beta designation might be removed. I don't have the need today but if I do, I would prefer not to use a beta product in production.
