Oracle rman 没有0级时1级备份和0级大小一样，可以用来做恢复 resetlogs后也可以

news 来源：原创 2024/9/20 9:01:36

文档说了 full backup 不能 用于后续的level 1，没说level 1没有level 0 是不是level 1就是level 0？

1级备份变0级的原因 及 Enabling Change Tracking生效没有-CSDN博客  这个文档说明1级备份时没有找到0级就是0级备份，可以用来完整恢复的。

GOAL

What are incremental backups? Why are archivelogs still required to recover a database from an 'online' incremental backup?

Discuss the relationship and/or dependency between incremental backup and archivelogs.
 

SOLUTION

Incremental backups can be either level 0 or level 1. A level 0 incremental backup, which is the base for subsequent incremental level 1 backups, copies all blocks containing data, backing the datafile up into a backup set just as a full backup would. The only difference between a level 0 incremental backup and a full backup is that a full backup cannot be used for level 1 backups.

A level 1 incremental backup can be either of the following types:

  • A differential backup, which backs up all blocks changed after the most recent incremental backup at level 1 or 0. This is the default.--差量

  • A cumulative backup, which backs up all blocks changed after the most recent incremental backup at level 0--增量

You can take incremental backups of databases, individual tablespaces or datafiles.

The two most important reasons for making incremental backups are:

  • For use in a strategy based on incrementally updated backups, where these incremental backups are used to periodically roll forward an image copy of the database. This is known as an incremental merge, or the "Oracle Recommended Backup" strategy.

  • To save time and space for daily backups - perhaps take a level 0 on the weekends, and level 1 on the weekdays.

All incremental backups are can be taken in either ONLINE or OFFLINE backup mode. All ONLINE backups, incremental or otherwise, need archivelogs for recovery.

For demonstration purposes, see the restore preview from an ONLINE backup below:

Media recovery start SCN is 10270514   [4]
Recovery must be done beyond SCN 10270514 to clear datafile fuzziness
Finished restore at 19 FEB 2013 14:25:43

From the above we can see:

[1] -- this is the level 0 backup

[2] -- this is the level 1 backup

[3] -- if the last backup is a level 1, we only need archivelogs generated during the period of the level 1 backup. The archivelogs generated during the level 0 is not required for recovery.

0-1级之间的archivelog不再需要了！！

[4] -- this SCN is when the incremental 1 was taken, confirming once again that we need archivelogs starting from the latest incremental level 1 backup

A level 0 restore preview is also attached to this note.

This applies to 10g as well as to 11g.

Note: Incremental level 1 backups are never used for block media recovery (BMR). RMAN will restore the block from the level 0 backup, and then apply all archivelogs from the level 0 onwards. 如果没有archivelog，不能block级别恢复， 只能0级恢复datafile 再1级恢复datafile ，在用archivelog了

视图：v$block_change_tracking
查看块跟踪的状态，跟踪文件的大小及位置

 

查看当前块跟踪的状态
SQL> select status from v$block_change_tracking;
STATUS
----------
DISABLED    --->关闭状态

 

也可通过后台进程CTWR（修改跟踪进程）判断，CTWR进程负责维护新的修改跟踪文件
ps -elf | grep ctwr | grep -v grep

 

开启块跟踪
SQL> alter database enable block change tracking;
Database altered.

 

SQL> select * from v$block_change_tracking;
STATUS    FILENAME                           BYTES
---------- ------------------------------ ----------
ENABLED   /u01/app/oracle/ORCL/changetra  11599872
          cking/o1_mf_8zqj5157_.chg
跟踪文件是自动在db_create_file_dest设置的目录下生成的，大小约11M

 

通过后台进程CTWR判断
ps -elf | grep ctwr | grep -v grep
0 S oracle  10379   1 0  75  0 - 186111 ?   22:30 ?    00:00:00 ora_ctwr_orcl

 

关闭块跟踪
SQL> alter database disable block change tracking;
Database altered.
关闭块跟踪会删除跟踪文件

 

SQL> select status from v$block_change_tracking;
STATUS
----------
DISABLED

 

如果db_create_file_dest目录没有设置，也可以在开启块跟踪时直接指定路径
SQL> alter database enable block change tracking using file '/u01/app/oracle/track.log';

Database altered.

 

SQL> select * from v$block_change_tracking;
STATUS    FILENAME                      BYTES
---------- -------------------------- ---------
ENABLED   /u01/app/oracle/track.log  11599872

 

更改跟踪文件的位置：


--可以使用alter database rename 语句来修改跟踪文件的位置，该命令会更新控制文件里的信息，命令必须在mount 状态下执行，如果数据库不能shutdown，那么可以先disable块跟踪，然后再指定新的位置，但是这样会丢失以前跟踪文件里的数据。

 

关闭数据库
SQL> shutdown immediate

 

移动文件
mv /u01/app/oracle/track.log /u01/app/track.log

 

启动到mount
sqlplus / as sysdba
SQL> startup mount

 

修改文件位置
SQL> alter database rename file '/u01/app/oracle/track.log' to '/u01/app/track.chg';

 

OPEN数据库
SQL> alter database open;

 

查看
SQL> select * from v$block_change_tracking;
STATUS    FILENAME                      BYTES
---------- -------------------------- ---------
ENABLED   /u01/app/track.chg         11599872


注释：
在使用RMAN 增量备份的情况下，启动块跟踪，在做增量备份时会缩短RMAN 备份的时间，因为不用扫描整个数据库。但是块跟踪也会带来其他的一些开销。所以要根据实际情况决定是否启用块跟踪。
