What to enter
| Input | Meaning and units |
|---|---|
| Full backup size (GB) | Enter full backup size in GB; use the same basis as the other measurements. |
| Daily incremental backup size (GB) | Enter daily incremental backup size in GB; use the same basis as the other measurements. |
| Incremental backup days (days) | Enter incremental backup days in days; use the same basis as the other measurements. |
Understanding your result
Read Total backup storage (GB) in the units and model stated on this page. The formula total = full + incremental * days defines the relationship; measurement accuracy and model applicability are separate from numerical precision.
Common mistakes
- Mixing input units or changing the physical meaning of a variable without changing the model.
Check your calculation
- Use the worked example as a known reference case, then change one input at a time and check the direction and units of the response.

How much storage will one full backup and daily incremental backups use?
Calculate a simple backup storage requirement from supplied backup sizes.
Common uses
- How much storage will one full backup and daily incremental backups use
How it works
total = full + incremental * days
Worked example
Enter Full backup size: 1000 GB; Daily incremental backup size: 100 GB; Incremental backup days: 7 days. Results: Total backup storage: 1700 GB.
