There are several options in this space, but Backblaze approaches the backup issue from an exclusionary perspective. If you’re scratching your head at that explanation, try this. Rather than having to select all the files and folders that you believe you want to keep safe via backup, Backblaze assumes you want it all by default. It’s then up to you to filter out specific files and folders, and clip out media types and file sizes that you want Backblaze to ignore.
For only $5 per month, you get unlimited backup for a single computer (and connected drives). If you’re unsure — that’s a sweet deal. Restoring from their webpage is easy, and you can browse your backed-up file tree if you just need a specific file. You may opt to download zip files of your data, or pay for DVD media or USB hard drives with your restore data.
