Hi I think he was talking about the "fragmentation" of the snapshot. In cassandra 1.0.X all ColumnFamilies are in the same directory, but in cassandra 1.1.X each ColumnFamily is in its own directory, and snapshots of each ColumnFamily are inside this directory.
1.0.X Snapshot directory: /cassandra/data/<KeySpace>/snapshots/<cassandra_bkup_files> 1.1.X Snapshot directory /cassandra/data/<KeySpace>/<ColumnFamily>/snapshots/<cassandra_bkup_files> In 1.0.X you can restore a Keyspace backup by copying just one directory. In 1.1.X it seems you need to copy one directory for each ColumnFamily, which is a little more complicated. 2012/12/1 Tyler Hobbs <ty...@datastax.com> > The nodetool snapshot command has keyspace and column family options (from > nodetool --help): > > snapshot [keyspaces...] -cf [columnfamilyName] -t [snapshotName] - Take a > snapshot of the optionally specified column family of the specified > keyspaces using optional name snapshotName > > > On Wed, Nov 28, 2012 at 5:40 AM, Adeel Akbar < > adeel.ak...@panasiangroup.com> wrote: > >> Dear All, >> >> I have Cassandra 1.1.4 cluster with 2 nodes.
