I am using VxDBA (A utility in Veritas database Edition) for the oracle database backup. The procedure is
1. Shutdown the database
2. Take a snapshot using VxDBA (Full data Storage Checkpoint)
3 Mount the storage check point
4. Startup the database
5. Taken the backup from the storage check point (offline backup)
Then I found all the files are backed up. But the total size of the datafiles are not matching with the size of the backup taken. So I restored few files from the backup set and ls -l command shows the correct files size for each file. But du -ks and df -k dosent show the correct usage of the space. Again I copied 3 files to another location and found all the file statistics are correct.
Do anybody know this problem , why there is a size difference..? Can I believe this backup..?
I am using Oracle 7.3
OS : Sun Solaris 8 ( I know this is aan odd combination.. But our application need old version)
File system : Vxfs
DB size 80GB
I appreciate your help..
