- I would like to get Macrium's stellar reliability and quality and facilities when backing up Linux servers. To be a good alternative to r1soft and acronis.

Reflect supports Linux partitions. But it doesn’t actually run on Linux. And to my knowledge, at least one of the reasons for that is that Linux doesn’t have an equivalent to Windows VSS, which allows making a snapshot of a live file system as well as allowing applications to take preparatory steps before that occurs. Having a “tidy” and static snapshot is crucial to capturing an image of a running system so that you can be confident that the data was captured in a reliable, non-corrupted state. However, if my admittedly limited Linux knowledge is outdated on this topic and there is something as robust and widely supported by applications as Windows VSS, then another possible reason might be that porting an application such as Reflect onto a completely different OS platform is likely to be a non-trivial task in terms of initial development and ongoing maintenance/support. I do remember that Reflect long ago offered an option to build Linux-based Rescue Media, but that was dropped due to low usage.

@jphughan you can makeshift something like VSS but you'll have to code it specially for different software, you can take a snapshot with copy on write with LVM, and you can tell databases to flush tables with read lock or similar to take a consistent snapshot before letting them write again. That's not the innovation part needed.

The innovation needed is in the CBT. There's no equivalent to it in Linux, and that's the main selling point of products like r1soft.
Macrium doesn't need to make a whole GUI in linux, just an agent part and have it controllable by a windows application or API.
