Disaster recovery refers to a methodology through which key operational data can be recovered at the time of its loss or corruption, when things tend to go beyond one’s control, such as natural disasters or hardware failure.
Hardware can still be either replaced or repaired, but data generated manually or electronically cannot be recovered or restored at all times. Businesses are required to keep their vital data protected, especially the ones which are important for their continuous operations, through integrated online data backup and disaster recovery solutions.
Company data should be stockpiled securely offsite in such a way that it can be recovered at the time of a disaster or uncontrollable incident. Basically, there are two methods for online data backup and disaster recovery. These are Disk-to-Tape Backup and Disk-to-Disk Backup.
In case of Disk-to-Tape Backup, you enjoy two benefits:
- It is economical comparative to media
- Tapes can be removed to be stored offsite and supply an extra protective layer to loss of data.
