I like the idea of using Glacier as a Backup solution for ones devices. However one thing worries me: Looking at the Glacier pricing table[1] there is a section 'Request pricing'. This looks to me like there is a price of 5.5 cents per 1000 upload request. Considering Arq will upload multiple times an hour, this looks like it could amount to quite a bit. With two uploads per hour I arrive at 5$ per month, but there could be significantly more uploads. Even 5$ would already be a 50% price increase compared to only the storage pricing for 1TB of data.

Could anyone clarify whether my calculation is wrong?

2 uploads an hour = 48 uploads a day

48 a day * 31 days a month = 1488 uploads a month

5.5 cents per 1000 uploads

so this would cost roughly 1.5 * 5.5cents, so about $0.0825 a month.

There would be data and storage costs but I'm just going by your upload request calculations.

damn, I had a factor of 60 in there, for some reason I calculated 2 uploads per minute instead of per hour. Alright then, seems to be a fair price.
The way Arq splits files into chunks (to facilitate incremental backups), it averages $.05/GB in per-request Glacier fees for the initial backup. After the initial backup, per-request fees are typically not significant because it only uploads new/changed files.
Glacier should be used for data that won't be changed frequently (e.g. purchased music/movies). Hence you can backup to glacier daily.

S3 is more suitable for things you are working on like codes.
