Types of Data Backup

Types of Data BackupBacking up your company data is essential in today’s IT and storage environments. Companies cannot afford to lose the valuable customer, employee and business data that they have spent years collecting.

Not only does it take years to collect but, it also takes untold amounts of capital to generate and maintain data.

There are many different types and ways that data can be backed up from tape and disk storage to cloud storage and off-site physical storage.

We thought it would be a good idea to walk you through some of the more popular solutions. There are 4 main backup solutions that seem to be favored by IT professionals and businesses.

Backup Type Data Backed Up Backup Time Restore Time Storage Space
Full Backup All Data Slowest Fast High
Incremental Backup Only new/modified files/ folders Fast Moderate Lowest
Differential Backup All data since last full Moderate Fast Moderate
Mirror Backup Only new/modified files/folders Fastest Fastest Highest

Full Data Backup

Full data backup is when you take a complete copy of all the data in your database. This includes all files and folders. Full data backups are great because they make restores of some or all of your data fast. The problem is that it can take a long time to do a full backup.

When all the data in a database is being copied it can take long hours. Another drawback of a full data backup is that it takes a large storage resource to store all of the data. Think about how much space your databases currently occupy on your servers. Now double that exactly and you have how much space would be needed to carry out a full backup.

Incremental Data Backup

Incremental data backup is different from a full backup in that it does not backup all information from your databases. Instead, it only backs up new or modified files from the point at which the last full or differential backup has occurred.

The advantage of incremental data backup is that it is much faster and takes much less storage space than a full backup. The downfall is that when you are restoring information, each incremental backup needs to be processed separately. This take more time than in a full backup but is still manageable.

Differential Data Backup

The differential data backup stores all files that have changed since the last full backup. This is different from incremental in that the incremental backup stores all data since the last full, differential and incremental backup.

The differential data backup takes moderate time for backup and storage but limits the restore time to be very low. The issue with the differential backup is that the storage needed can grow to a larger size than the original full backup.

Mirror Data Backup

Mirror data backups are very similar to full backups except that the files are not zip compressed. Mirror backups can also be password protected and be accessed via tools like Windows Explorer. Mirror data backups provide advantages in that they are the fastest in backup and restore time. They provide disadvantages in that they take up the most storage space on servers.

Each backup type provides advantages and disadvantages. The truth about data backup is that each situation should have a custom data backup plan. Some businesses need to have an emphasis on rapid restoration. Others need an emphasis on limiting storage space to save costs in the short to mid-term.
