SAP Sybase IQ provides four types of database backups:
Full backup makes a complete copy of the database.
Virtual backup copies all of the database except the table data from the IQ store.
Incremental backup copies all transactions since the last backup of any type.
Incremental-since-full backup copies all transactions since the last full backup.
All these backup types fully back up the catalog store. In most cases, the catalog store is much smaller than the IQ store. If the catalog store is larger than (or nearly as large as) the IQ store, however, incremental backups of IQ are bigger than you may want or expect.
Incremental virtual backup is supported using the BACKUP statement.
Temporary store data is not backed up. However, the metadata and any other information needed to recreate the temporary store structure is backed up.
