Restoration real size not reflecting on client side

Hi Folk,

We have solaris 10 master,media server(7.6) and client is redhat linux(7.6).We are trying to restore oracle RMAN Level 0 backup and i could see on GUI showing 3.1TB restoration completed currently and still restoration running.But we could see on client side only 750GB completed now.Why its not reflecting 3.1 TB on client side?

Any one help on this.Is there real size will reflect once all restoration complete?

the size that is showing on

the size that is showing on GUI Restore window is the data Read size by bptm.. that is not actually write Data on Destination.

you can only find the write data by seeing the Destination client path and how much is actaully committed in disk 

in your case 750 GB is actaully write data. and to write the 750 GB data ...netbackup needs to read 3.1 TB data on the tape...

If restoring from a

If restoring from a multiplxed tape the 3.1TB is what Netbackup has read from tape. But a lot of the data does not belong to the Oracle backup and has been discharded. This is the price you pay for using MPX backup - restore is slower.

Hope it explain.

Hi Nicolas, Currently RMAN

Hi Nicolas,

Currently RMAN restoration is running with multi channel mode.I mean those 3.1 TB size is showing currently completed channel not running channel.I hope if the channel showing status code 0 should be real size on GUI right?

Not really for MPX restore.

Not really for MPX restore. If running non-mpx restore or restore from disk - you can trust the number in the GUI.

If your environment are uses

If your environment are uses a rman catalog database you can get the dba to find the database size there.

If still possible you can check the size of the level_o (full) backups under the client backup report, but this only gives the size of the filesets received from rman so it only be a guide.

Another way is to list the backup images under catalog, with the same caveat as the client backup report

The standard questions: Have you checked: 1) What has changed. 2) The manual 3) If there are any tech notes or VOX posts regarding the issue
