FAQ and Troubleshooting
(a)About Software FAQ
1.What are the situations that may causes data loss?
There are many factors that lead to data loss including virus infection, software failure, data corruption, hardware breakdown and human faults. Typically, following symptom may appear:
- BIOS could not detect the hard disk drive
- Power surges result in "no disk drive found" error
- Missing folders or files
- Accidental deletion, format or fdisk
- No boot device
- Operating System not found
- Primary Hard Disk not found
- Master Boot Record Not Found

4.How can I minimize the chances from disastrous data loss?
User can minimize data loss by following certain guidelines that includes:
The user can minimize the chance of loosing the precious data or files by taking the backup of all the files or folders so that when the original data is deleted, user is able to get the copy from backup.
User can use antivirus software and update it at least four times per year to save data or files from virus infection.
Using UPS (uninterrupted power supply)
In the event of an electricity surge or lightning strike, a UPS can protect user system from electrical loss. A UPS is also a back up power source that keeps user’s computer running for a short period of time, giving the opportunity to properly save the work and shut down the system to avoid a potential data loss.
5.When and how often I need backup of my data?
Backups should be taken on a regular basis to protect files against numerous losses. The frequency of back up depends upon the maximum amount of work that can be lost in the event of a disastrous failure.
If the backups are faulty, a simple data loss can quickly become a data disaster. Even if backups are successful, they only contain data collected during the most recent backup session. As a result, a data loss can not give user the most current data, despite of backup attempts. The best way is to backup all important data at every 24 hours.

Complete backup is a full backup of the entire server or computer system client hard disk drive. For a server it includes all volumes, files and folders. For a PC client it includes all drives, files and folders.
Differential backup copies all files that have been changed since the last complete backup. Differential backups are useful when it is important to have the latest version of each file.
Incremental backup copies all files that have been changed since the last backup. This type of backup is used when each revision of a file must be maintained.
User-defined backup is a special backup requested by a group of employees on a mission-critical project copies a user-defined set of files.
