原创 ttserver备份和还原 收藏
由于人为的错误操作或机器的不可靠性等原因导致数据的丢失，这是经常发生在我们身边的事，所以需要定期的备份，ttserver为我们提供了很好的备份功能。
启动服务
ttserver -port 19780 -thnum 8 -dmn -pid /tmp/test.pid -log /tmp/test.log -le -ulog /tmp/ -rts /tmp/test.rts /tmp/test.tch
插入数据
tcrmgr put -port 19780 localhost key value
查询数据
tcrmgr get -port 19780 localhost key
得到的结果是：value
备份数据
tcrmgr copy -port 19780 localhost /tmp/backup.tch
kill掉ttserver
删除数据
rm /tmp/test.tch
恢复数据
cp /tmp/backup.tch /tmp/test.tch
重启ttserver
ttserver -port 19780 -thnum 8 -dmn -pid /tmp/test.pid -log /tmp/test.log -le -ulog /tmp/ -rts /tmp/test.rts /tmp/test.tch
再次查询数据
tcrmgr get -port 19780 localhost key
得到的结果仍是：value，说明成功的还原了数据
