snapman.sys is a kernel mode driver with start type 1 (loaded by ntldr) therefore it can't be compressed, it's executed as a part of windows kernel so it does not create any visible process just as most of the other kernel-mode drivers.
Alex Vlasov
Snapman.sys is a file used by Acronis Partitioning software to provide the ability to recover damaged boot partitions during a DOS based recovery attempt. Removing these files will result in a damaged boot partition (Master Boot Record), and thus inability of the computer to start/boot into the OS. (further information...)
