Verifying your Tapes: BEFORE YOU DELETE media files on Disk
DNA Evolution enables you to verify media on a tape. Verification is performed at a number of levels to ensure media is safe. Follow these steps to verify your tape:
Step 1: Make sure the tape you are verifying is write-protected. (See reference image)
Step 2: Browse to the “My Clients” tab and load the tape you want to verify into an available drive.
Step 3: Once your tape is loaded, make sure it is un-mounted (see next image). In this example, Tape AYX406 is selected for verification. It is loaded into drive st0 but not mounted. This tape is ready for verification.
Step 4: Click the Verify Tape button
Step 5: The verify window will open (as shown in previous image). The drive and tape-id will be preselected. You can add additional tapes to the verification list. DNA Evolution will automatically load each tape in the list and verify each file by checksumming every byte against the original source checksum. This guarantees a byte-for-byte quality check.
Step 6: Once your verification is completed, a detailed report is available in the Admin Dropbox.
Step 7: To view the detailed report, browse to the Admin Dropbox and the Validate Tape folder (shown in next image).
Step 8: In the Validate Tape Reports folder, you will find reports per tape and then per archive on tape. In this folder, you will find a number of reports. For every verification run, the following reports are generated:
In the example above, two archives were on that tape. Each archive has a corresponding set of verification output files. The master.xml file gives a file-by-file result and checksum, while the report.log gives a summary.
