Backing Up After You Change the Physical Schema

You must perform a level-0 backup of the root dbspace and the modified storage spaces to ensure that you can restore the data when you:

• add or drop mirroring.
• add, move, drop, or resize a logical-log file.
• change the size or location of the physical log.
• change your storage-manager configuration.
• add or drop a dbspace, dbslice, or logslice.
• add, move, or drop a chunk to a dbspace.

You must perform a level-0 backup of the modified storage spaces to ensure that you can restore the data when you convert a raw, static, or operational table to standard. This backup ensures that the unlogged data is restorable before you switch to a logging table type.
