Minarca equivalent to Change Block Tracking

[Erick Perez]

not knowing the correct term in Minarca, does it implement something like Change Block Tracking and in what virtual environments is supported (like proxmox for example).

thanks for your comments.

Hello Erick,

Thank you for your question.

To clarify, Minarca is a file-based backup solution, not an image-based backup system. It uses rdiff-backup, which in turn relies on librsync to efficiently store only the differences between files. This helps reduce storage usage and speeds up transfer times.

However, Minarca does not implement Change Block Tracking (CBT). CBT typically requires integration with the underlying file system or hypervisor to track changes at the block level, which is more common in image-based or volume-level backup systems. As Minarca operates at the file level, this kind of low-level tracking isn't supported.

That said, Minarca can still be used in virtual environments such as Proxmox, as long as it can access the file system of the guest or host where the files to back up reside.

Please let me know if you'd like more details or have further questions.
