saas2cloud is a backup service, so we only take the latest changed version of a file, in backing up Box.com.
This means that there is only one automatic backup a day. Although Box supports file versioning, saas2cloud only takes the latest version each day. This is to prevent storage requirements increasingly sharply.
Therefore, you will often see a discrepancy between the amount of storage Box reports and the amount that saas2cloud reports. Depending on how many versions are kept and how large the files are, the difference in storage size can be large.
