How can I backup locally?

I have 2 of those 14TB shucked drives, a 3.5TB Toshiba HDD, and a 1TB HDD from an old laptop. I would like to keep all of them, but I’m of course focusing on the 14TB drives. Is there a way to write data or partition to protect against drive failure or do I need another 14TB to run RAID 5? I’d rather not as it kind of irks me to have $600 in drives. I’d like to utilize that 3.5TB and maybe another, cheaper drive (a $70 4TB maybe) to run some sort of local backup in conjunction with the big bois, but I don’t know how to. Of course there’s Backblaze, so I could theoretically run no local backup and wing it, but I’m thinking that might be foolhardy. Thoughts? I’m leaning towards just using backblaze and hoping the drives don’t fail for a long time.

  1. First thing to note is that RAID is not a backup. It protects against a drive failure but not from ransomware or even simply deleting file by mistake. Putting 14TB drives in any RAID is a significant capacity loss. So, first, define if you need RAID at all. Then, calculate the amount of important data you are willing to backup. User Backblaze Personal for all data for example plus the most important data to 3.5TB drive.

  2. RAID 5 with 3 14TB drives and duplicati or rclone to Backblaze. Backup tools: [https://www.vmwareblog.org/single-cloud-enough-secure-backups-5-cool-cross-cloud-solutions-consider/](https://www.vmwareblog.org/single-cloud-enough-secure-backups-5-cool-cross-cloud-solutions-consider/)

  3. Often it is possible to group data in three major piles.

    1. Data that is important and you absolutely must not lose. Family photos, insurance documents, things you have created, yourself.

    2. Data that is less valuable, but that may represent some effort or cost. A media library, an ebook collection, comics. You may have put in a lot of work to fix metadata and locate rare missing items.

    3. Data you can easily download again or replace some other way.

    Most likely the really important pile is relatively small. You should be able to back this up with at least three copies. Using two different types of storage. And keep one copy at a remote location, so even if the house burn or is burglared, you have a copy. One backup copy may be on a RAID5 NAS. Another on a external HDD. And yet another in the cloud. Perhaps also another copy on some old HDDs you don’t know what to do with.

    The second pile is most likely the biggest. Stuff you may only have one backup copy of. Mainly to prevent you from deleting everything by some silly mistake. RAID doesn’t provide any protection against this, and deleting files by mistake is most likely the most common reason for data loss. And the most embarrassing. This backup copy may also be stored on the backup RAID5 NAS.

    The rest you don’t bother to backup. Perhaps you just keep it on your main NAS. Perhaps RAID. Perhaps mergerfs and snapraid. Perhaps some DAS?

    I just use rsync to create my backups. Use something that you can check does what you want it to do. And so you can access the backup copies if needed.

    I never buy just one HDD. Always at least two. One for storing data. One for backup. Perhaps even two for backup.

  4. Not sure what your real goal or budget is here, but….

    With the drives you have, mirroring your 14tb drives is the logical choice, but you loose half the capacity. Next logical jump is to get two more 14tb drives and do RAID6 or RAIDz2 on ZFS.

    Use the 3.5TB drive as a “downloads” folder to store things in transit and take some write cycles of the main storage, especially if doing BitTorrent.. Use the 1TB drive as a backup drive for your system disk.

  5. Local backup – use backup software. Many options exist.
