Given all the vendors that provide this service with both Windows and Linux clients, Code42 is the only one I am aware of that supports sets. For me, this was essential to prioritize urgent data over low risk changes in the event a disaster occurs while a large directory is taking days to upload. I would use sets with priorities and any changed data that was important would interrupt data of negligible importance.
This worked well, however Code42 always bothered me as the software delivery was low quality on Linux, it was a tar file and only implemented sysv scripts and they did not have a cli interface. I worked around this as long as I could until they retooled the app based on electron and as bad as the ui was, it got worse.
At this point I would rather switch vendors. Anyone know of another that meets the criteria, from what I can see it doesn’t look like any support sets?
