Block level backup is a feature of incremental backup. Compared with other backup types, block level backup needs less time and storage space. This post on MiniTool Website shows you more information about this type of backup. Scroll down to get more details.

What Is Microsoft Block Level Backup?

Block level backup is a feature of incremental backup that allows you to upload only changed and added blocks instead of whole files. This type of backup is always done by taking snapshots of the running volume and data is read from the snapshot.

With snapshot technology, you are able to copy the files even if they are in use and even reduces the impact on the performance of your devices during the backup process.

Advantages of Block Level Backup

Less storage space – Block level backup allows you to upload only the changed parts of files instead of the whole files. Data is read from the snapshot, which will decrease the load on the disk with the data.

If you need to back up to cloud storage, block level backup will help you to save some costs on storage space.

Faster upload time – Only the changed part of the file is sent to the backup repository, so the backup process will be much faster.

Disadvantages of Block Level Backup

Although the advantages of block level backup are evident, it also has some shortcomings.

Longer time to recover your data – If you need to recover a single file in the block-level backup, the backup program needs to check all blocks of that file including the initial full backup. Therefore, it will take quite a long time to recover the data.

Less data reliability and consistency – To recover your data, you need all the consequent blocks to remain in their places. If any block becomes corrupted or inconsistent, it will influence the ability to recover the whole file negatively.
