Mastering Incremental Backup: Step-by-Step Guide

I. About incremental backup

1. What is incremental backup

Incremental backup is an intelligent backup method. It only backs up the changed part, that is, after the last backup, it backs up the new or changed data. Each incremental backup is the same as the last backup (you can is a full, differential, or incremental backup). For example, if a full backup is performed on Monday and an incremental backup is performed on Wednesday, the incremental backup on Wednesday will back up the changed data after the full backup on Monday. If another incremental backup is performed on Friday, then this time Data that has changed since Wednesday’s incremental backup will be backed up.

2. The difference between incremental backup, full backup and differential backup

A full backup is to back up all the selected data, generate a mirror image of the backup file, and then save it to another hard disk partition. Differential backup is to back up the changed data after the first full backup, and each subsequent differential backup is compared with the first full backup.

Comparison of the advantages and disadvantages of incremental backup, full backup and differential backup:

II. How to perform incremental backup?

1. Software that supports incremental backup: Renee Becca

Renee Becca It is a tool specially used for system/hard disk data backup and restoration. It can help you back up and restore important data in your computer, such as programs, system configuration, emails, photos, videos, documents, bookmarks, etc. It adopts the leading incremental/differential backup technology, which can save you more time and disk space. In addition to supporting system backup, it also supports partition backup, hard disk backup, file backup, and disk cloning to meet your needs. need.

2. Incremental backup using Renee Becca

Incremental backup with the help of Renee Becca is very simple, the following will take (file backup) as an example to explain, the specific operation steps are as follows:

Step 1: Download, install and run Renee Becca on the computer, and select the (File Backup) option in the main interface (Backup) column.

Step 2: Next, select all the files that need to be backed up in (source file (device)), and select the hard disk partition to store the backup data in (destination).

In addition, in (task plan), you can make a daily/weekly/monthly automatic backup plan and click (confirm) to enable the automatic backup function.

In (Backup Scheme)-(Scheme Type), you can choose a suitable backup scheme mode according to your personal needs. Renee Becca has 5 backup schemes to choose from, namely version chain mode, single version mode, overall mode, incremental mode and diff mode. Select (incremental mode) here, you can choose according to the actual situation (after the initial full backup, only create an incremental backup), or you can choose (create a full backup after every X incremental backups), and set the automatic Clean up the plan and check (Keep the first backup version), the latter may take up more storage space, but the backup file will be more comprehensive, and it is not easy to restore the complete backup file due to damage or loss in the middle data.

Step 3: Finally, click the (Backup Now) button to start executing the file backup command according to your settings, and you can see the progress of all backup tasks on the task bar. After the backup is complete, you can click the (Restore) button to restore the files to the specified hard disk when necessary.

Step 4: Then select the location where the files are to be restored, and click the (Restore) button.
