I'm looking for home archival of personal data, photos, work documents, etc. I am an independent freelancer and work from home mostly so it's not only private data but also work related.

I'm aware of the difference between backup and archiving. I work on Apple devices so I have all my work data synced through iCloud (documents folder is steadily synced with Apple iCloud).

What I'm looking for is a solution for data archiving for data which I don't want to have on my local machine but only on the archive media. It's data starting at about year 2000 and consists mostly of private family photos and other personal stuff. Currently about 500GB of data.

Currently I have it all spread over three HDD harddisks. I've also put it all together into one big archive on a new LaCie USB-C HDD. I'm afraid one of these HDDs might fail someday so I'm looking for a solution.

I don't have a network at home (only use iPhone 4G hotspot for internet) so I have no Ethernet connectivity for a NAS or similar. I was thinking of a NAS with RAID 1 although I know it's rather meant for data availability than archiving since it can fail as a whole too.

What do you recommend for my case? I have a feeling there is no "best practice" here and I'm a bit lost. I've tried pCloud (similar to Dropbox but better server availability in EU) but I hate their web UI, I think it's really outdated and ugly and that is something that keeps me from a product. I'd really like to have the data on my site too.

    If I may pick a nit: you do not have your "work data backuped through iCloud." iCloud drive is a file syncing service, not a backup service. A local NAS sounds like a great idea for the data you want to archive - you could also create time machine backups of your Mac devices on it. Something with RAID1 would work, letting you survive a single drive failure - but there are other raid levels that can handle more failures. For example, I'm running raidz3 on a freenas box, which can survive up to three failed disks.

  • Thanks @negacao but I do not have Ethernet connectivity, as described I don't use any networking / router at home. Are there solutuions similar to NAS but only with USB-C / thunderbolt connectivity?

  • Sure - I have not personally used one, but there are devices like this available (not necessarily saying that one in particular is great or anything, but it fits the bill). Then you can create a raid array using Disk Utility.

  • Apple sells a fancy, expensive one too.

    There is a lot of NAS hardware out there, most of it can easily be used with an Ethernet cable between Mac and NAS (no router required).

There exists many time-proven solutions for data archival - so there's lots of best practice advice around.

You indicate that you have no existing local network, you have a slow internet connection using a phone hot-spot and you have only about 500 GB of data collected over 20 years that you wish to archive.

In this case, I wouldn't have cloud services or NAS devices with old style hard drives in a RAID setup at the top of my list of technologies to use. Those come with recurring operating costs and other drawbacks.

Instead I would look to storing the data on optical disks or tape. Depending on the product used you have plenty of space, it is relatively cheap to make extra copies and it is local only technology. I.e. for example today you can optical disk recorders that store multiple terabytes of data on a single disk - however, I would advise you to start with one of the cheaper options ofcourse.

The advantage of being able to make multiple copies is that:

a) any copy will eventually deteriorate over time and needs to be replaced (this is also the case with RAID-volumes, where hard drives will eventually fail and need to be replaced)

b) you risk theft of the device, house catching on fire, water damage, etc. - so better to have multiple (encrypted) copies that you can store in other locations

For optical disc storage you can start with a simple BluRay. A good quality, archival grade disk probably lasts 20 years without you having to do anything except keeping scratches away. It is ofcourse best to keep them out of light, heat, vibrations, etc. as well.

I would say that with a budget of 300-400$ you can get a BluRay BDXL burner and a big pack of 100 GB archival discs so you can get all your data stored.

Another contender would be using the commonly available, very small sized, SD-cards. These are available at cheap in the capacities you seek, and it is easy to make multiple copies that can be stored in various locations (in the car, at a friends house, etc). They typically last longer than hard drives that have a life-span on average of about 5 years or similar.

  • There are archival optical discs that supposedly last much longer.

    Exactly, this is why I advise on optical disk storage. Lasts longer than hard drives for sure - but you still need to check in on them, check that they're good and make extra copies once in a while. It's just a difference between having to check on your RAID system every month, and having to copy your optical disk every 10 years. That's why I like optical discs for archival. Note that the 1000 year claim is most probably not true.
