Recovering Deleted/Lost/Missing Data From Novell Servers

Other effective data protection practices are hardware configurations such as RAID, periodic usage of good system checker software, reduction of dust around the work area, monitoring hard disk's for hardware faults (see Section 1.3: How data gets lost), effective cooling systems, updated anti-virus software, etc.

However, even backups (be it in the form of backup software or hardware configurations such as RAID) are not 100% foolproof and mishaps can occur in any situation. The only way to ensure complete data protection is a thorough knowledge of data storage and recovery processes – this will provide users with small but extremely vital bits of information such as immediate disconnection of affected disks, connection of failed disks to healthy ones, recovery of data to safe locations, etc. Thus, in a nutshell, while data disasters may occur at any time, 100% data recovery is definitely possible.
