Hadoop: 0.20.2
Hbase: 0.20.4, r941076
Hi,
I've running a hbase table on 4 regionservers with 4 datanodes back cross on
the same machines. After restart hbase and hadoop I've lost the one and only
hbase table. The hbase-master-log says:

The data are already present in HDFS:
Found 5 items

What can I do for recover the hbase table or how can I backup the data from
time to time?
