Procedure documentationBackup I/O Locate this document in the navigation structure

 

In the I/O Operations user menu, you can find, among other things, a display of read and write accesses during a backup.

Procedure

Open the Database Assistant (transaction DB50) or the liveCache Assistant (transaction LC10). Choose   Current Status   I/O Operations   Backup I/O  .

or

Open the DBA Cockpit (transaction code DBACOCKPIT) and select   Performance   I/O Operations   Backup I/O  .

Result

The system displays the number of read and write accesses on the individual volumes caused by a currently running backup action. An access corresponds to an I/O operation. This includes multiple pages, where the number can vary.

You can see the actual number of backed up pages in the column Saved Pages (Backup) .

It is therefore possible to monitor the asynchronous I/O operations that are caused by backups. You can refresh the display during a running backup, and in this way obtain a display of the progress of the backup run.

You can refresh the display. To do so, choose   Edit   Refresh  .

You can automate this function by choosing   Edit   Automatic Refresh On/Off  . The display for the function for the automatic refresh is above the header line of the table (green symbol: on, red symbol: off). In the field next to this, you can specify the time interval with which the automatic refresh should take place. The default value is 5 seconds.
