Each time Polarbackup runs; new, modified and changed files will be added to the backup. Small files will be taken as a whole file, for faster restoration. However, large modified files can be backed up using Polarbackup Block Level Technology. This technology is ideal for large files that undergo slight changes like databases, Outlook email files (PST) and so on. In this type of backup, only changes within the file will be backed up and not the entire file, saving more space and time.
To add more file extensions to the list of the files you wish Polarbackup to back them up using the Block Level technology, please apply the following:
- Open your Polarbackup desktop software.
- Click on the Settings option.
- Refer to the Advanced Settings.
- In the input box of the Block Level Extensions, type the extensions of the files you wish Polarbackup to back them up using this technology.
- Click the Save icon.
