I've been using Backblaze B2 since it launched, and HashBackup (I'm the author) was one of the first B2 integrations. What I like most about B2 is the transparent, no gimmick pricing. No monthly minimum, no minimum file size, no paying for storage for 90 days after you delete a file. And they give generous free allowances: 10GB/mo (forever, with no credit card required), 1GB of free egress per day, and up to 5000 free transactions per day. I backup the HashBackup dev server to B2 every night, around 80GB with mostly VM images, and the total backup size while keeping the last 30 days + 12 monthly backups is around 50 GB and costs 25 cents/month. They bill me every few months, I guess when enough charges accumulate. Here are the backup stats for the HashBackup dev server: [jim@bs ~]$ hb stats -c /hbbackup HashBackup #2527 Copyright 2009-2021 HashBackup, LLC Backup directory: /hbbackup 3,617 backups 334 TB file bytes checked since initial backup 80 TB file bytes saved since initial backup 910 total backup hours 79 GB average file bytes checked per backup in last 5 backups 23 GB average file bytes saved per backup in last 5 backups 29.78% average changed data percentage per backup in last 5 backups 13m 43s average backup time for last 5 backups 637 archives 55 GB archive space 84.11% archive space utilization 46 GB 810:1 industry standard dedup ratio 9.5 MB average archive space per backup for last 5 backups 2465:1 reduction ratio of backed up files for last 5 backups 234 MB dedup table current size 9,442,920 dedup table entries 48% dedup table utilization at current size 724,059 files 671,701 paths 10,550,610 blocks 127,965,672 block references 117,415,062 deduped blocks 12.1:1 block dedup ratio 5.2 KB average stored block size 616 GB backup space saved by dedup 49,648 average variable-block length
