What is a block level incremental backup?
Speaking of a block level incremental backup, we must figure out what a block level backup is at first. A block level backup, as its name refers, backs up small blocks of the source files instead of the complete files. It reads data directly from the disk or volume rather than from the database. Compared with a file level backup, a block-based backup reduces the storage space and time required by each backup.
A block level incremental backup only backs up changed blocks of the source since the previous backup and the rest blocks remain intact. Therefore, it further improves the backup efficiency and saves the required space.
Why do you need block level incremental backups?
As mentioned above, with block level incremental backups, you can save a lot of time and storage space while backing up data. There are more advantages that may make you feel an urge to have a try:
When you restore the image files created by block level incremental backups, only specific data blocks will be restored, which again saves you time.
Block level backup comes with snapshot technology, so files can be backed up even if they’re open in other software.
Since block level incremental backups have so many merits, how to create such backups in Windows?
How to create block level incremental backups step by step?
To create block level incremental backups in Windows, you may need a professional backup tool. AOMEI Backupper Standard, the best free backup software, can give you a hand.
It offers you the function of System/Disk/Partition Backup for block level backup and File Backup for file level backup. You can choose one backup type according to your situation.
It enables you to do incremental and differential backups to improve the backup efficiency.
It supports all Windows PC operating systems like Windows 10/8.1/8/7/Vista/XP. However, if you are running Windows Server operating system, please turn to server backup software.
Follow the steps below to create a block level incremental backup via AOMEI Backupper. Here take Disk Backup as an example:
1. Download, install and run AOMEI Backupper. Connect the external storage device to your computer if you want to backup the source disk to an external drive.
2. Click Backup on the left pane and select Disk Backup.
3. Click Add Disk to select the source disk to be backed up.
4. Click the second bar to select a destination path to save the backup image.
5. Click Schedule to see the scheduled backup options. Under the Advanced tab, “Incremental Backup” is selected by default. You can set the backup task to run daily/weekly/monthly under the General tab.
6. Confirm the operation and click Start Backup. Then, choose Add the schedule and start backup now to run the first backup immediately or Only add the schedule to run it later.
>> Options: you can enable email notification, choose the compression level for the backup image file and select intelligent sector backup or sector-by-sector backup.
>> Scheme: it will delete old image files automatically to save disk space for you. This feature is supported by AOMEI Backupper Professional and higher editions.
For incremental backup tasks, if one of the incremental image files in the sequence is damaged or missing, the subsequent image files will be invalid. It is recommended to perform a full backup after several incremental backups.
If you want to perform a scheduled differential backup, you need to upgrade to AOMEI Backupper Professional.
Above steps apply to run automatic block level incremental backups. If you want to run one-time incremental backups, you can create a full backup first, and then go to Home > the backup task > Backup > Incremental Backup.
Block level incremental backups make it quicker to backup and restore data and reduce the storage space required by each backup. AOMEI Backupper provides you with the easiest way to create block level incremental backups in Windows. Additionally, it can be used as bit copy software and CompactFlash card copier.
