AFAIK, Mopria doesn’t develop universal printing standards actually. The IPP standard was developed by Printer Working Group of IEEE. Of course, its members are almost same as Mopria. The standard Mopria developed is eSCL, a scanning standard. eSCL has a competitor, WSD, which was developed by Microsoft.
And snapshot can benefit backup. Since some software need to be shudown to do backup, minimize the down time is important. The snapshot can make down time is almost stop and restart time, and the software can be online again and we can do backup on snapshot in background.
