- System Fault Tolerancesearch for term
A means of protecting data by providing procedures that allow a network server to automatically recover from hardware failures. SFT protects data by providing data duplication on multiple storage devices; if one storage device fails, the data is available from another device. SFT offers three levels of protection: Hot Fix, disk mirroring or duplexing, and server mirroring. Each level of redundancy (duplication) decreases the possibility of data loss.
