Verify Data


  • All the Verify pages are structured in a similar fashion to each other.
  • Verify Data page has just one addition compared to other Verify pages.
  • It has an additional Radio Button option that allows the user to chose to verify:
    • By Date
    • By Tape Label

  • Selecting either of the two options and pressing the Go Button changes the GUI.


On choosing 'By Date' option the GUI opens to a page with the Calender control in left hand panel.

  • The Calender Control has enhanced features compared to usual such controls.
  • The current Date is shown as surrounded by a blue rectangle. In the Fig 2 above, Feb 26th is shown in such a way.
  • That does not mean that date has been selected.
  • To select a Date users have click the Date itself.
  • Clicking within the box will not select the date.
  • As you will come near the date in the rectangle, it will display an underscore sign (hyper link present indication).
  • Click then.
  • The Date Rectangle's color changes to a yellow-orange color to reflect that the hyper link has been visited.

  • All dates on which a backup has been run will display the Report Summary legend within themselves.

Tape(s) should be in the tape device before the verification can happen.

  • The text in upper right hand rectangle (No 3) will change to indicate that the Data Verification process has started.
    • Click the hyper link 'here' to see further progress.
  • Further progress messages/ error messages will appear in area 4 .
  • Even if there is no tape device attached, or the Tape has not been inserted at all, ZMC will wait for the time outs to be over before reporting the failure.
  • ZMC gives different types of error messages that originate from the Tape device.
  • If a verification task is already in progress, a second data verification task cannot be started for the same backup set.
  • If this is done the following error message is displayed.
