Description

The current implementation of incremental backup just moves WAL files into backup directory.The restore procedure of incremental backup relies on full restore (from snapshot) as source of all table meta.

Two problems:

1. Table configuration/properties may be changed after full backup and we will loose this info during restore
2. We can not convert WAL files into HFiles w/o having table description and layout. Need for merge tool
