What We Don't Backup

Backblaze does not want to waste your bandwidth or Backblaze datacenter disk space. Thus, we do not backup your operating system, application folder, or temporary internet files that are transient and would not be useful in the future. Backblaze also excludes podcasts in iTunes.

Certain Filetypes

You can see these exclusions by clicking on “Settings…” in the Backblaze Control Panel and selecting the Exclusions tab. These exclusions can be removed! Some of these excluded files are:

Other Backup Programs

Backblaze also doesn't backup backups like Time Machine and Retrospect RDB.

Deleted Files

Backblaze will keep versions of a file that changes for up to 30 days. However, Backblaze is not designed as an additional storage system when you run out of space. Backblaze mirrors your drive. If you delete your data, it will be deleted from Backblaze after 30 days.

Disconnected External Hard Drives

Your external hard drives need to be connected to your computer and scanned by Backblaze at least once every 30 days in order to keep them backed up.
