I worked at a company where we built this for our internal HBase clusters. Given any timestamp (or even better a commit ID) we could restore the cluster to that point in time. This was done through a combination of backing up the store files + write ahead logs. As I recall we had a retention limit for how much time we could do this for - but they were high enough for all of the "oh crap" moments.
