Verification Examples

The following examples show how to verify an existing backup and how to verify immediately after backing up.

Performing Verification Only

To verify a backup of all storage spaces, use the onbar -v command. The logical logs are not verified.

To verify the backed-up storage spaces listed in the file bkup1, use the following command:

onbar -v -f /usr/backups/bkup1

Performing a Point-in-Time Verification

To perform a point-in-time verification of a backup, use the following command with the datetime value in quotes:

onbar -v -t "2001-12-10 10:20:50"

Verifying a Whole-System Backup (IDS)

To verify a whole-system backup, use the following command:

onbar -v -w

Verifying Blobspaces (IDS)

The onbar -v command cannot verify the links between data rows and simple large objects in a blobspace. Use the oncheck -cD command instead to verify the links in a blobspace. For information on oncheck, see the IBM Informix: Administrator's Reference.

Verifying Sbspaces (IDS)

The onbar -v command verifies only the smart-large-object extents in an sbspace. For a complete check, use the oncheck -cS command. For information on oncheck, see the IBM Informix: Administrator's Reference.
