What is the volume of daily backups?

Precisions

Security is one of the key points of data centers and backups are one of the elements involved in this security. The volume of backups is cumulative. Individually, the volume of data to be backed up tends to grow, and the different backup sets multiply this effect. Unmodified data does not need to occupy backup spaces unnecessarily. Incremental backups reduce the environmental footprint of this process. Some solutions are able to provide such incremental backups, others, however, can only archive in full, which increases the environmental footprint.

Use Case

Hosting technical documentation allow to follow up backups sizes and location
