That could be easily done with bulk loads http://hbase.apache.org/bulk-loads.html it will really depend on how fast you can get the data out of sybase providing that you have the appropriate hardware for hbase.
More than a year ago we loaded a bit more than a 1TB (pre-replication) into 20 machines using "normal" MR jobs before bulk loading existed and it took a few days, a lot of the time was actually spent on waiting on the source database. Can't tell if it's gonna much faster, since it's don't know what it would be compare to.
