Hi, I’ve been setting up my home TrueNAS 12 Core server to do a daily Cloud Sync to AWS S3 in the “Deep Archive” storage class. My idea was to have the lowest possible cost to have a cloud backup for my 3 TiB of files.
However, after two months of using this, I got a little bit overwhealmed with the actual bill.
My first month on AWS cost me around $52. The largest expenses were 312,077.000 S3 Glacier Deep Archive PutObject Requests ($15.6), 45,067,343.000 Requests-GDA-Tier2 ($18) and 3,258,245.000 Requests-Tier1 ($16)
I thought “It is probably the cost of the initial upload, it should get smaller”, but next month I got a $100 bill with 1,059,800.000 S3 Glacier Deep Archive PutObject Requests ($53), 42,571,946.000 Requests-GDA-Tier2 ($17) and 3,127,319.000 Requests-Tier1 ($15)
The largest cost are those “PutObject Requests” that I believe are still part of my initial upload. (I have a much lower cost on that on the current April bill), but I’m still finding the “Requests-GDA-Tier2” a bit high.
Are those “Requests-GDA-Tier2” happening when I’m checking for file changes (Cloud Sync) every day? Are there any backup recommendations to try to lower those recurrent costs? The Storage costs themselves are VERY cheap, but those request costs are really expensive!
Alternatively, if anyone here have any recommendations of a cheaper alternative to AWS S3, I would appreciate it. I was considering Backblaze B2, that would cost me $15 for storage. But I’m afraid I might also find some unexpected billing in their “transaction” costs. What are you people seeing as transaction costs on your daily backups with Backblaze?
