It is always advisable and prudent to secure your data through proper back up and move it offsite. It should be stored offsite so that it can be easily accessed whenever the previous or present data is required.
While restoring the backed up data or while working on such data, the purpose of the exercise should be restoration of data only, because some times the change made by one user may delete some data useful for another user.
Nowadays, there are several trustworthy and highly dependable companies you can approach to secure your backup and ensure recovery of vital information whenever necessary. Several avenues for off site server storage, replication of data centres and other ideas are readily available.
Before you engage a service provider for the task of Data Protection, you need to check the firmís track record. Talk to its existing clients and find out about the quality of their services and infrastructure, such as availability of highly secure locations for backups, proper facilities and adequate servers for safe keeping of data.
A new Continuous Data Protection (CDP) server after initialising itself with a complete data set executes a full backup to disc. Once this is done it will at designated intervals, say every 5 minutes or every hour execute incremental backups. This is done as and when there is a change of log of email or data base system.
CDP is a highly developed backup system, which will perform backup operations only when there is an actual change in the file. The entire changed file is not backed up. This means that there will be less data on backup, helping the backup process to run faster and smoother.
More frequent backups can be performed because the overhead of each backup is reduced considerably. This increases productivity and curtails and reduces lost work. The backup frequency is greatly enhanced thus improving performance. The burden on the administrator is also greatly reduced on account of this.
The other benefit in this improved system is that the CDP products are application-and file system Ė consistent. Achieving business continuity through data protection is indeed crucial in successful running of a business.
