Sybase IQ provides a backup log, .backup.syb,
to help you manage your backup media. 
This log is not used to create the backup or to restore the
database; however, information describing the backup or restore
is recorded in this file during both Backup and Restore.
Note: To display only the information about a particular backup,
you can run RESTORE with the CATALOG
ONLY option. This option displays the header file for
a backup from the media rather than from the file, so that the DBA
can identify what is on the tape or file.
