What is a backup?
Simply put, a backup is an additional copy of computer files which are recoverable in case files are lost or damaged.
What is Backblaze?
Backblaze is an active, mirroring backup software and service that transfers a copy of your files to Backblaze's servers, and keeps them there, updating with new and changed files as you update and change them on your computer.
If a file is lost, deleted or damaged, Backblaze retains a copy of that data for 30 days, so you can restore it back to your computer.
Backblaze doesn't limit the amount of data you can back up from your computer's hard drive, or locally connected external drives.
What isn't Backblaze?
Backblaze is not designed as an archiving service or cold storage of data you no longer want to keep on your computer, nor is a replacement for a hard drive when you need more storage on your computer.
Backblaze is not a sharing service to distribute or share files over the internet or a collaboration/syncing service.
