Jonathan Hsieh commented on HBASE-7410:
---------------------------------------
Change order of paragraphs -- snapshots allow you to.... prior to version xxx,
the only way to backup ...
{code}
+ <para>The only way to backup or to clone a table is to use
CopyTable/ExportTable,
+ or to copy all the hfiles in HDFS after disabling the table.
+ The disadvantages of these methods are that you can degrade region
server performance
+ (Copy/Export Table) or you need to disable the table, that means no
reads or writes;
+ and this is usually unacceptable.
+ </para>
+ <para>HBase Snapshots allow you to take a snapshot of a table without too
much impact on Region Servers.
+ Snapshot, Clone and restore operations don't involve data copying.
+ Also, Exporting the snapshot to another cluster doesn't have impact on
the Region Servers.
+ </para>
{code}
Mention that is on by default in 0.95+, off by default in 0.94.6+?
{code}
+ <section xml:id="ops.snapshots.configuration"><title>Configuration</title>
+ <para>To turn on the snapshot support just set the
+ <varname>hbase.snapshot.enabled</varname> property to true.
{code}
Mention that it is an indepedent table with read/write perms.
{code}
+ <para>From a snapshot you can create a new table (clone operation) with
the same data
+ that you had when the snapshot was taken.
{code}
sp: clusters
{code}
The tool executes a Map-Reduce job, similar to distcp, to copy files
between the two cluster,
{code}
Mention something about ACL's required if security is on in this section or in
the security section?
