I was asked by my manager to take the archivelog backup of a 10.2.0.4 database using RMAN every two hours for a production database on sun solaris.Definitely, i am not going to sit at every 2nd hour and take the backup manually.So,best was to write a shell script and put it in cron job.Cron is a unix, solaris utility that allows tasks to be automatically run in the background at regular intervals by the cron daemon.Now the question was “What will i write in the shell script”.I can set the crontab for every 2 hrs and i can use something like “from time ‘sysdate-1/12’ “.
RMAN> backup as compressed backupset archivelog from time 'sysdate-1/12' format '/oracle_db_storage/testb/arch_070210_%s_%p';
This will check for all the archivelogs generated from 2 hrs back to the current time and take the backup.If suppose i run the command at 11am then it will take the backup of all the archivelogs generated between 9am – 11am.So i can write the script and put it in cron job which runs every 2 hrs and my job is done.Good enough, isn’t it?????
BUT!!!!! what if the cron didn’t run at the time it was supposed to?????? Suppose the cron job didn’t run at 11am, and it ran at the next run cycle that is 1pm, will everything be the same then??? No, cause at 1pm it will backup only those archives which are generated after 11am (current time – 2hrs).I won’t have backup of the archives generated between 9am to 11am.Thats BAD !!!!!!
So, definitely i need to change the script.After few searches with oracle documents i got exactly what i needed
“not backed up integer times ” :- Backs up only those archived logs that have not been backed up at least integer times.
From Oracle Document :-
notBackedUpSpec
Syntax Element Description NOTBACKEDUPBacks up only those files (of the files specified on the command) that RMAN has never backed up. This option is a convenient way to back up new files after adding them to the database. SINCETIME=‘date_string‘Specifies the date after which RMAN should back up files that have no backups. The date_stringis either a date in the currentNLS_DATE_FORMAT, or a SQL date expression such as'SYSDATE-1'. When calculating the number of backups for a file, RMAN only considers backups created on the same device type as the current backup.This option is a convenient way to back up files that were not backed up during a previous failed backup. For example, you back up the database, but the instance fails halfway through. You can restart the backup with theNOTBACKEDUPSINCETIMEclause and avoid backing up those files that you already backed up. IfASBACKUPSETis set, then this feature is only useful if RMAN generates multiple backup sets during the backup.When determining whether a file has been backed up, theSINCEdate is compared with the completion time of the most recent backup. ForBACKUPASBACKUPSET, the completion time for a file in a backup set is the completion time of the entire backup set. In other words, all files in the same backup set have the same completion time.integerTIMESBacks up only those archived logs that have not been backed up at least integertimes. To determine the number of backups for a file, RMAN only considers backups created on the same device type as the current backup.
This made my day 🙂 . I tested it on my test db and it worked as needed 🙂
The test was done on 2nd Feb 2010

Now even if the cron didn’t run due to some reasons, the next time it runs, all the archivelogs that have not been backuped 1 times will be backed up.I won’t miss any archivelog.It was a new learning for me..

3 thoughts on “Rman – Archivelog Backup”
HI Anand,
Nice article.
i want to achieve the below :
Fri Full RMAN Backup with Archived Logs
Sat to Thursday Only Archived Logs
Again on Friday Full backup.
Could you pls help how to achieve this ?.
Regards,
Shadab
One thing you might want to try as well is this rman script:
(script)
sql ‘alter system switch logfile’;
backup archivelog all delete input;
(/script)
This switches the logfile at start of backup, then backs up all logs and deletes them. Next time you run this, no matter how much later, it will only backup anything created since.
Hi Nuno,
Thanks for visiting my blog and putting a nice suggestion.I haven’t written the full script in the blog, have just showed the major part of change in the script.But yes before the backup starts ‘alter system archive log current’ is fired and then the backup starts.
Regards,
Anand
