What storage do I need if I want app files backed up automatically every night?

To back up app files automatically every night, you need backup storage that’s:

1. Large enough to hold the data you want to protect

   • At minimum, size it for the total amount of app files
   • Better: allow extra room for version history, logs, and future growth

2. Dedicated or separate from the source device/server

   • So if the app machine fails, the backup is still safe

3. Accessible to your backup method

   • Examples: external drive, NAS, cloud storage, or a backup server

4. Reliable and ideally redundant

   • For important data, use storage with redundancy like RAID/NAS or cloud backup with versioning

Practical rule of thumb

• If your app files are 100 GB, don’t just buy 100 GB of backup space.
• Aim for 2–3× that amount if you want nightly backups with history and room to grow.

Common options

• External SSD/HDD: simple, cheap, local backups
• NAS: good for automatic scheduled backups on a network
• Cloud backup: offsite protection, automatic, usually best for disaster recovery

If you tell me:

• how much data you have,
• whether this is for a phone, laptop, or server,
• and whether you want local or cloud backups,

I can recommend the right storage size and setup.
