💡 Backup Planning Tips

  • For critical data, follow the 3-2-1 rule: 3 copies, 2 different media, 1 offsite
  • Test your backups quarterly to ensure recoverability
  • Consider air-gapped backups for ransomware protection
  • Monitor storage growth and adjust your plan annually

This free backup space calculator will help you estimate your storage requirements based on the inputs that you provide. It gives you the estimated cost that you’ll pay for cloud or local backups. Also, you get suggestions for the recommended storage solution, i.e. server, cloud, NAS, etc.

Let’s understand all the inputs

1. Primary Data Size

The total amount of data you need to back up initially.

2. Type of Data

This input determines how much data will change on the daily basis. You get multiple presets but if you are not sure, you can simply choose general file at 5% change. The custom presets are as follows:

  • Documents: 5% change rate (small daily changes)
  • General Files: 10% (default – typical office files)
  • Databases: 30% (frequently updated records)
  • Media Files: 50% (large video/photo edits)
  • Custom: Set your own percentage

3. Monthly Growth Rate

This takes the input in the percentage of how much data grows on a monthly basis. This helps in calculation but if you want to keep the backups stable in terms of total data, keep it at zero.

4. Retention Policy

Here, you’ll decide how long the data will be retained in your backup medium. Here are the presets you get.

  • 30 days: Basic protection
  • 90 days: Standard (default)
  • 1 year: Compliance/legal needs
  • Custom: Advanced control over daily/weekly/monthly/yearly retention

5. Compression

Compression helps with saving the storage space and the total amount that you are investing in your backup solution. It reduces the backup size but the total time taken for restoration will be higher as you increase the compression. The need for complex computation increases as we increase the level of compression. Here are the presets that you get:

  • None: 0% savings (raw files)
  • Medium: 30% smaller
  • High: 50% smaller (default)
  • Maximum: 70% smaller (CPU intensive)

6. Redundancy

Redundancy is for the protection of your data in case of drive failure. This will be important if you are considering a self-backup solution like the local backup in your computer or RAID. The more redundancy you choose, the more storage space will be required for the same amount of data. Here are the presets to choose from:

  • Single: No duplicates
  • Dual: 2 copies (default – basic protection)
  • 3-2-1: 3 total copies (2 local, 1 offsite – gold standard)

In the results, you will get a detailed analysis of your backup strategy, i.e. the initial amount of data, backup count, projected final data, required storage, etc. The cost estimation includes cloud storage as well as the local HDD and SSD setups. With the total amount of data that has to be backed up, you get suggestions for the best systems with enterprise NAS/SAN, server, cloud, and hybrid systems.

Note: This tool gets multiple inputs to understand your storage requirements and runs fully on the front end. We do not save any of your data anywhere. I hope this helps you plan your backups in a better way.
