I’m trying to store a backup of recordings we’ve been making for the past three years. It’s currently at less than 3 TB and these are 5 - 9 GB files each, as mp4s. It will continue to grow, as we generate 6 recordings a month. I don’t need to access the backup frequently, as the files are also on my local machine, on archival M-discs, and on a separate HDD that I keep as a physical backup and sync two regularly. I also have Backblaze in the background. So when I go back to edit the recordings, I’ll be using the local files rather than the ones in the cloud.

However I really want someplace to drop a recording immediately after it’s done that’s off-site in the cloud, just in case of an immediate disaster.

They are currently on Sync.com, which offers unlimited space for $30/mo, but the service’s stopped providing support of any kind recently (despite advertising phone support for their higher tiers) so I’m worried they’re about to go under or that something is up with their company.

I had considered AWS Deep Archive, but their egress cost seems insane as the service is really meant for “archives” as far as I understand it, not as a backup I might very infrequently access.

What other options are out there to consider?
