Closed potasz closed 7 years ago

potasz commented 7 years ago

Prerequisite:

Steps done to restore:

  1. filter S3 data for snapshot, hosts, keyspace and table
  2. check the target nodes if the tables to be restored are available (i.e. schema created)
  3. crete all the directories in _download_rootdir (/var/tmp)
  4. download filtered data from S3 into _download_rootdir maintaining host/keyspace/table structure
  5. from each downloaded directory load the sstables with sstableloader to _targethosts
  6. remove downloaded S3 file once restore was successful
