EVMS supports writable snapshots, using copy-on-write from an EVMS volume. I haven't tried it with read-only DASD, but in theory it should be possible for it to be used this way. The act of creating the snapshot might require writing to the original volume in order to update the volume metadata.
I thought this was done by keeping the dirty data in page cache until the moment where you open the flood gates again after you did the backup of a consistent not-changing device?
