Verifying Your Backup Media

Use the VSTORE command to verify that your backup media is good and can be used in a recovery. This step can prevent the possible loss of data resulting from attempting to restore files on a tape that is damaged or defective.

The parameters for the VSTORE command are defined below:

Parameter	Definition
`ONERR=`	Specifies what to do if `VSTORE` encounters an error. To stop processing if it encounters an error, use `ONERR=SKIP`. To continue, use `ONERR=SKIP`.
`SHOW`	Specifies where to display the results of the `VSTORE` command. To display them on the console, use `SHOW`. To print the results, use `SHOW=OFFLINE`.
`LOCAL`	Use to verify files that were written to tape from a group and account other than the logon account of the verifier.
`DIRECTORY`	Use to verify the file system directory.

To verify your tapes

To verify your backup tape set, do the following:

Create a backreference by entering:
FILE TAPEFILE;DEV=TAPE
Enter the VSTORE command to verify the copies of the files in the specified directory. For example, to select all files in all groups in all accounts and display the results on the console, enter:
VSTORE *TAPEFILE;@.@.@;ONERR=QUIT;SHOW;LOCAL;DIRECTORY

To use the file equation issued by the system for your logon user name, use a semicolon as a place holder for the tape file reference. For example:

   VSTORE ;@.@.@;ONERR=QUIT;SHOW;LOCAL;DIRECTORY

To print the results of VSTORE

To print the results of the VSTORE command, add the parameter SHOW=OFFLINE. For example, to select all files in all groups in all accounts and print the results, enter:

   VSTORE ;@.@.@;SHOW=OFFLINE




	NOTE: Once you have created your backup tapes and are ready to restore them, you can use the new `CHECKSLT` command to check the tape and to estimate the amount of contiguous disk space required on LDEV 1 for the restore.
