达梦V8归档备份参数NOT BACKED UP的使用
2024-06-04 05:20:33
期望只备份某个时间后的归档
只想备份2022-05-20 11:43:40以后的归档
BACKUP ARCHIVE LOG ALL NOT BACKED UP SINCE TIME ‘2022-05-20 11:43:40’ BACKUPSET ‘/dm8/backup/arch_bak_11’ ;
实际效果则分2种情况
1、与已存在的归档备份最后一个文件的close time时间有重合情况，则备份当前归档目录上的没有备份过的；
2、不重合，则将当前归档目录上的文件，全备份
验证脚本
只要出现粉色断档情况，则归档全备份
第一次验证
####在2022-05-20 13：45：00这个时间点
####数据库的归档情况，一共有58个文件

[dmdba@dmdb1 arch_bak_11]$ 第一次结论：因为没有任何归档的备份的文件，执行从 SINCE TIME ‘2022-05-20 11:43:40’ 时间开始的归档，进行备份，
结果：将’2022-05-20 11:43:40’之前的和’2022-05-20 11:43:40’之后的都备份了，
简单说：没有备份的全部备份了
二：验证
执行一些数据变更，生成一下归档文件create table tb01 (id int) tablespace tbuser;begin
for i in 1..10000 loop
insert into tb01 values (i);
end loop;
end;
/alter system switch logfile;###过2分钟begin
for i in 1..10000 loop
insert into tb01 values (i);
end loop;
end;
/alter system switch logfile;###过2分钟begin
for i in 1..10000 loop
insert into tb01 values (i);
end loop;
end;
/alter system switch logfile;三：验证：####在2022-05-20 13：56：00这个时间点
####数据库的归档情况，一共有61个文件

本次（第二次）只：从 SINCE TIME ‘2022-05-20 13:48:46’ 时间开始的归档，进行备份59–61，
三：验证
四：执行一些数据变更，生成一下归档文件create table tb01 (id int) tablespace tbuser;begin

[dmdba@dmdb1 arch_bak_14]$ 三：总论：
第一次备份，没有备份，从1到58全部备份
第二次备份，从 SINCE TIME ‘2022-05-20 13:48:46’ 时间开始的归档，进行备份，比与第一次归档备份58号归档开启时间大：13:43:19，关闭时间小：13:48:47，只进行备份59–61，
第三次备份，与第二次备份归档的最后文件时间没有重叠，从1到65全备份
从 SINCE TIME ‘2022-05-20 14:01:50’ 时间开始的归档，进行备份，比与第二次归档备份61号归档关闭时间大：13:56:29
比62号归档的开始时间大：13:58:38，关闭时间大：14:01:40
简单说：出现断档了，丢62号，结果从1到65全部备份；
自动补齐归档
1、本次发起的备份时间与已存在的归档备份最后一个文件的close time时间有重合情况，但归档备份是并没有将当前归档目录上的没有备份过的，达梦将会自动补齐归档
下面例子是：
除73-77的归档备份保留，其他都删除
执行since 73归档close time，
达梦将自动补齐备份1-72，和备份78-79，不在备份73-77
