建立不支持增量备份的全备份
做一个全备份，fileFull为不支持增量的全备份
$ ttbackup -type fileFull -dir /tmp/backupdir sampledb_1122
（ttbackup -type fileFull -dir 指定存放目录 要备份的表明 ）恢复到原数据库
$ ttrestore -dir /tmp/backupdir sampledb_1122
Restore started ...
Restore failed:

使用流式全备份和恢复
流式备份的特点是输出到stdout，因此可以定向到文件或磁带等，或在线压缩如：
备份：ttbackup -type streamfull sampledb_1122|gzip > sampledb1122.ttb.gz
恢复：gunzip -c sampledb1122.ttb.gz | ttrestore -i sampledb1122
$ ttbackup -type streamfull sampledb_1122 > sampledb_1122.ttb
Backup started ...
Backup complete
$ ll sampledb_1122.ttb
-rw-rw-r-- 1 oracle oracle 44842736 Apr 5 06:18 sampledb_1122.ttb $ ttdestroy sampledb_1122 $ ttrestore -i sampledb_1122 < ./sampledb_1122.ttb Restore started ... Restore complete $ ttisql -v1 sampledb_1122 Command> select * from test; < 1, 2016-04-05 05:35:53.000000 >增量备份和恢复
ttbulkcp结合ttschema进行逻辑备份和恢复
ttbulkcp可以将表中的数据导出成ASCII文件，反向亦可。
但每次只能导出一个表，如果批量导需要自己写批处理文件，如下面示意：
$ ttisql -v1 -e "tables;exit" plsqldb|while read tab; do
> echo ttbulkcp $tab
> done;
ttbulkcp ORACLE.COUNTRIES ttbulkcp ORACLE.DEPARTMENTS ttbulkcp ORACLE.EMPLOYEES ttbulkcp ORACLE.JOBS ttbulkcp ORACLE.JOB_HISTORY ttbulkcp ORACLE.LOCATIONS ttbulkcp ORACLE.REGIONS ttbulkcp ORACLE.T1 ttbulkcp ORACLE.TT_TEST导出：
ttbulkcp -o 导出后的文件名 表的明=========>整张表导出$ ttbulkcp -o plsqldb employees employees.dump107/107 rows copied
$ more employees.dump

导入：
ttbulkcp -i导出后的文件名 表的明=========>整张表导出（导入导出就是参数不一样，一个-i，一个-o）
$ ttbulkcp -i -connstr "dsn=sampledb_1122;uid=tthr" employees employees.dump Enter password for 'tthr': ttBulkCp: Error received while retrieving information about table employees -- Table not found. 由于目标库的表结构还不存在，这时我们可以用ttschema导出表定义 $ ttschema plsqldb oracle.employees > employees.sql Warning: objects may not be printed in an order that can satisfy foreign key reference constraints or other dependencies $ cat employees.sql -- Database is in Oracle type mode Warning: objects may not be printed in an order that can satisfy foreign key reference constraints or other dependencies create table "ORACLE".EMPLOYEES ( EMPLOYEE_ID NUMBER(6) NOT NULL, FIRST_NAME VARCHAR2(20 BYTE) INLINE, LAST_NAME VARCHAR2(25 BYTE) INLINE NOT NULL, EMAIL VARCHAR2(25 BYTE) INLINE NOT NULL UNIQUE, PHONE_NUMBER VARCHAR2(20 BYTE) INLINE, HIRE_DATE DATE NOT NULL, JOB_ID VARCHAR2(10 BYTE) INLINE NOT NULL, SALARY NUMBER(8,2), COMMISSION_PCT NUMBER(2,2), MANAGER_ID NUMBER(6), DEPARTMENT_ID NUMBER(4), primary key (EMPLOYEE_ID) ); create index "ORACLE".EMP_MANAGER_IX on "ORACLE".EMPLOYEES (MANAGER_ID); create index "ORACLE".EMP_NAME_IX on "ORACLE".EMPLOYEES (LAST_NAME, FIRST_NAME); 不过我们看到ttschema导出的文件中包含了用户名，如果需要在另一个用户如tthr的schema下建表，则需要使用vi替换一下 (1,$ s/ORACLE/TTHR/g) $ ttisql -connstr "dsn=sampledb_1122;uid=tthr;pwd=tthr" -f employees.sql $ ttbulkcp -i -connstr "dsn=sampledb_1122;uid=tthr" employees employees.dump Enter password for 'tthr': employees.dump: 107 rows inserted 107 rows total
