Ozhosting Cloud Backup compresses your files during a backup to increase efficiency.

This means that the data takes up less space (fewer bits) after compression than before. This reduces the burden on your Internet connection during backups and the files will take up less space on the Backup Server. You won’t notice anything of this process: when you retrieve the compressed files, they will be decompressed automatically and thus restored to their original state.

Is my storage space on the server based on compressed files?

Yes. Your storage space, for example, 10 GB, represents the amount of storage for compressed data on the Backup Server. So, on your computer, this amount could be 20 GB.
