full offline backup and restore

Registered by khaled Bouaziz on 2015-02-20

Full offline backup/restore of Trafodion is performed using HBase snapshot feature. Snapshots are a light weight way to keep the current state of a table without copying the data. After making changes to a table or in case of recovery restoring the snapshot gives the previous state of the table. More on snapshots can be found at: http://blog.cloudera.com/blog/2013/03/introduction-to-apache-hbase-snapshots/
Snapshots are taken for all the Trafodion tables including the Trafodion metadata tables and then exported to a HDFS location. When we need to restore the backed files from the HDFS location the snapshots are imported to the target system and then restored
