Automating Backups

I am taking the backups by using the following files:

Parameter file

Userid = 'test/test@test'
File = d:\testbackup\exp_test.dmp
Log = d:\testbackup\exp_test.log

Batch File

exp parfile=d:\testbackup\test.par

I have automated the task using the Windows scheduler.

When ever i take the backups it overwrites the previous backup file.

Now can i modify my script so that i can include date in the filenames.

Also can i keep the backup for say 3 days and then delete the same modifying the script.

I am using Windows 2000 Advanced Server and Oracle 9i.

Any suggestions for the same.

exp/imp is not a viable backup methodology for a production database.

Well i agree its not a viable method for taking backups of production databases.
But is there anyway to modify my script.

Well, you can but it is a little tricky. Here is an example of what we do here.

First you need to schedule your export, no problem right?

Next you will need another .CMD file scheduled to generate compression. Something like this...

**********************************************************************
REM the script is for generating script for compressing export backups

sqlplus export/export @D:\export\hanky\gen_code.sql
D:\export\hanky\compress_dump.cmd
*********************************************************************
The above is loggin into SQLPLUS and calling gen_code.sql first, that .SQL file would look like this.

*********************************************************************
set echo off
set pagesize 0
spool d:\export\hanky\compress_dump.cmd
select 'cd D:\export\hanky' from dual;
select 'zip d:\export\arch_export\DB_NAME_'||to_char(sysdate,'MMDDYYYY')||
'_backup.zip d:\export\*.dmp' from dual;
select 'copy d:\export\*.log d:\export\arch_export\bkup_'||to_char(sysdate,'MMDDYYYY')||
'.log' from dual;
spool off
exit
*********************************************************************
Now this is assuming you have a D:\export directory that your scheduled export writes to. This is timestamping the next .CMD file which will grab/zip and relocate your .DMP and .LOG files.

The first .CMD file is also calling "compress_dump.cmd" that file would look like this.

**********************************************************************
cd D:\export\hanky

zip d:\export\arch_export\DB_NAME_06142004_backup.zip d:\export\*.dmp

copy d:\export\*.log d:\export\arch_export\bkup_06142004.log
********************************************************************
As you can see the date has been filled in from the first command file.
I think you will also need to copy the winzip .EXE into the D:\export\hanky directory, it is called Zip.exe

Remember the ZIP command is zipping TO dir ----> FROM dir.

Confusing?
