backblaze backup/restore by b2 cloud

記錄一下 ... 上次rollback有點慘...

主要是看了這一篇才有的想法 ...

Extract snapshot into (browseable) bucket?
by u/josefrichter in backblaze

總之因為 b2 有 cloud partner https://www.backblaze.com/cloud-storage/solutions/compute, 所以traffic 過去不用錢

然後 VULTR > B2 也不用錢

所以有以下的花招:

1. b2 personal archive as zip to b2 cloud,
2. copy archive zip to cloud partner and
3. exact actual file in cloud parter VPS
4. and sync it back to B2 cloud bucket
5. rclone everything back to your local.

細緻一點的説明

1. b2 personal backup zip to b2 cloud ( 5T each due to vultr EBS limit, free )
2. create vultr vps with 10T EBS ( maximum 10T seems )
3. copy b2 cloud zip file to vultr ( free per B2 cloud partner )
4. unzip this archive file ( VPS cost per hour )
5. sync exact file back to b2 cloud bucket directly ( free per B2 cloud partner )
6. repeat 1-5 until all file served
7. rclone sync from b2 bucket to whatever you like

VULTR 現在每個顧客有 2T free egress, ( 是不是... )

1. 1.-4 same as above
2. traffic 2T to your source, change another vultr id and repeat

更暗黑的一招, backup b2 to pikpak (PP)

1. from 1-3
2. sync 2T zip into PP
3. unzip from PP UI
4. problem: you can't encrypt before sending into PP

也記錄一下，當下 2024/04 我在 b2 personal 有 ~ 26T..

照上面的玩法，如果我硬碟都毀了，rollback all data back to my storage 成本大概是

1. 26 T 壓成 5T 的時間 ( 5 times )
2. 5T * 5 repeat 上面 1-5 的 VPS/EBS cost ( 應該 < 100 USD )
3. 從 b2 cloud rsync 所有東西回 local 的成本 ( 1G = 0.01 USD, 26 * 1024 * 0.01 ~= 267 USD ), 如果可以流到 google drive 不用錢就可以用 google drive 20T $3300/Mo 的方案了...
4. B2 Cloud bucket usage per hour，我壓了一個 ~10G 的東西從 b2 website 測試抓回來的速度然後推一個假設的可能時間

   2. 用了光世代 500/500 + Wired Mac Mini 大概 19M/s, 看起來時間成本會比較貴
      1. 19M/s = 66.7G per hour
      2. 24 * 1024 / 66.7 = 400 hour = 17 Day (!)
   3. 但感覺看起來 B2 cloud backup 是 1T $6/Mo, per day $0.2 USD, 26 * $0.2 * 17 = $9 USD
5. 算起來大概.... 369 USD, $1200 TWD, 對於 DR 來說，應該也不算貴... 1T 成本大概在 $14USD?
6. 應該有更最佳化的路... 但現在夠好了。
