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