Otto backup to bb b2 bucket

I have 2 servers backup to my b2 bucket typicaly for many months its been < $20 a month the last bill for this month was nearly $80 and estimate for next month is $100 or more.

Is there anything that otto would be doing to cause a lot of transactions or downloads?

I doubt it has anything to do with Otto just covering all bases as BB support requested I check.

Hi @OceanWest -

OttoFMS offsite backups use rclone to push data to any S3-compatible storage provider. With Backblaze B2, Class B and C transactions are generated whenever buckets or objects are listed or queried (HEAD requests), including during multi-part uploads.

These transactions typically occur when using the File Browser in OttoFMS or the Cloud Console, and anytime data is uploaded. If your solution uses external container storage and you’re backing those folders up as well, the large number of small individual objects can significantly increase these transactions.

Hope that helps clarify!

thank you for the details that is informative -

i think in this case it could be the forums software being hit by a ton bots from China - have put some more rectrctions by geography with cloudflare.
