Differential backup details

Differential Backup is a backup strategy that is similar to incremental backup, but has some key differences. A differential backup backs up all the changed data since the last full backup, not all the changes since the last backup. This means that the differential backup file will get larger over time, but it will still save a lot of storage space compared to backing up all your data every time.

Here are some points on how to perform a differential backup and how to take a differential backup:

Steps to perform a differential backup:

1. First Full Backup : First, perform a full backup. This backup includes all data and files.
2. Differential backup : Next, perform the first differential backup. At this point, all changed data since the last full backup is backed up. This differential backup file is relatively small.
3. Perform differential backups regularly : In subsequent backup cycles, you can perform differential backups regularly. The backup content is all changed data since the last differential backup. These differential backup files will also gradually grow in size, but will be smaller than backing up all your data each time.
4. Recovery process : To recover data, you first need to restore the most recent full backup and then apply the most recent differential backup. This way, you can restore your data to its most recent state.

Advantages of differential backup:

• Relatively saves storage space : Compared to backing up all data every time, differential backup files are usually smaller and therefore save storage space.
• Relatively fast recovery speed : When restoring data, only the most recent full backup and the most recent differential backup need to be restored, instead of all incremental backups, which can speed up the recovery.

Disadvantages of differential backup:

• Backup files grow in size : Over time, differential backup files grow in size, potentially resulting in increased storage requirements.
• Increased recovery time : Although differential backups can be restored faster than full backups, recovery times can become longer as the backup file size grows.

Overall, differential backup is a backup strategy that can be very useful in certain situations, especially when you need to save storage space while maintaining relatively fast recovery speeds. However, performance and storage requirements for backup and recovery can change over time, so your organization's needs and resources need to be considered when choosing a backup strategy.
