Description

1) Trafodion has to be offline for the entire duration that backup script runs. This could be several hours.
2) Backing up a small table's snapshot takes several seconds. When there are hundred or more small tables this impacts overall backup time
3) Number of mappers used to backup or restore large table snapshots is not depenent on table size
