Comment on How do you backup your data?
clavismil@lemmy.world 1 year ago
I perform a backup once a week from my main desktop to a HDD, then once a month I copy important data/files from all nodes (proxmox, rpi’s and main desktop) to 2 “cold” unplugged HDD that’s the only time I connect them. I do all of that using rsync with backup.sh and coldbackup.sh
I use syncthing for notes across mobile/desktop/notebook, for that and other important files the backup goes to Google Drive or MEGA (besides the offline backup).
I want to try S3 Glacier since is cheaper for cloud backup… has anyone tried?

tl;dr it’s too expensive for what it is (cold storage), retrieval fees are painful, and you can often find hot storage for a similar price or cheaper.
The fees to restore data make it cost prohibive to have disaster recovery runs (where you pretend that a disaster has happened and you have to restore from backup) and we all know that if you don’t test your backups, you don’t actually have backups.
Restores are also slow - it takes several hours from when you request a download until you’re actually able to download it, unless you pay more for an expedited restore or instant retrieval storage. This is because the data is physically stored on tapes in cold storage, and AWS staff have to physically locate the right tapes and load them.
Glacier also isn’t even that cheap? It looks like it’s around $4/TB/month, whereas $5/TB/month is a very common price for hot storage and plenty of providers have plans around that price point. I wouldn’t pay more than that. If you need to store a lot of data, a storage VPS, Hetzner storage box, Hetzner auction server, etc would be cheaper. You can easily get hot storage for less than $3/TB/month if you look around :)
