NetWare protects data by providing duplicate directory entry (DET) and file allocation tables (FAT) , by providing features such as packet signature and the Transaction Tracking System, and by enabling the use of an uninterrupted power supply (UPS). A general discussion of these features is provided in this section.
NetWare also provides system fault tolerance by redirecting data from bad blocks to reliable blocks on the server's hard disk, and by mirroring and duplexing partitions. For information about these features, see Contents > Disks and Storage Devices > Understanding > Redirecting Bad Blocks and Contents > Disks and Storage Devices > Managing > Mirroring and Duplexing.
