What is the importance of data backup in web hosting ?

If you have a website , files or system settings then you must always perform a backup plan for your data to keep them safe from catastrophic damag , so you can get them back anytime .

 

So what are the factors affecting your data ? 

 

• Delete any data by human error .
• Applying wrong settings .
• Viurs and Hackers .
• Hardware damage or even updates that affect the content .

 

You can perform data backup with more than one way : 

 

• Same Server “ Eternal Backup “ 

 

It’s to keep the backup on the same server that hosts the data already , you can do that in 2 ways :

 

• Either the backup will be on the hard disk that stores the data, but this is a risk , cause If any problem occurs in the hardware , you will lose the backup and the data .

 

• Or you can download the backup on another hard disk separated from the one that stores the data , but this is also a risk , because if your server got hacked you will lose all the data .

 

• Different Server  “ External Backup “ 

 

It’s to store the backup on another server than the one that has the original data , this option is safe and not risky , and it will be better if the backup server is hosted in different data center , that’s why it’s important to carefully choose a company that has reliable backup servers .

 

Backup Typs :  

 

• Full Backup : 

 

The full backup is to make a backup for all your data that want to protect each time in a compressed and encrypted form , It is performed several times in a certain period of time, Although it is a safe way to protect your files, it’s not frequently used as it takes a long time and requires a large storage space, which costs alot of money especially if you have a high volume of data .

 

• Differential Backup : 

his type of backup involves backing up data that was changed since the last full backup , therefore it requires a full backup to be performed , It takes less time than the full backup and much less time to restore it , that’s why this type is the best in disaster recovery situations when time is a vital factor for business continuity .

 

• Incremental Backup :

 

This type of backups only stores changes that were made to the last backup version , it also requires a full backup version , as each incremental copy is stored separately for easy restoration .

It takes less time to be performed than full backups and also less time when restore each incremental backup separately, but you will need a long time to restore several copies together to go back to a specific period of time .

 

•  Mirror Backup  (Snapshot ) 

 

It’s the same as the full backup type but the only difference is that , this one the data It not being compressed or encrypted so it takes much less time than full backup as well as when restoring it , but one of its main drawbacks is that it needs more storage space .
