I checked with support and they informed me there is a 5 GB size limit with the product - because of an older 5 GB limit on the B2 side.

Once thing you can try (I have not tested this so cannot confirm if it will work) is to create a B2 bucket as S3 Compatible (on the B2 side).Refer to this post about how to do this. https://kb.msp360.com/cloud-vendors/backblazeb2/backblazeb2-as-s3compatible

Then create a new storage connector in Explorer using S3 Compatible:
You may need to select Version 4 Signature when setting up the account in Explorer.
Select the option to use native multi-part upload.

Do a test on a large file to see if we use the multi-part API to move the file to B2. Do a test copy from B2 back to local.

Hi,

Appreciate this is a bit older now, but is it possible to revisit the 5GB limit for Blackblaze? I'm encountering the same issue, and with datafiles only getting bigger each year, this would seem to be something that might hold others back.

Thanks!
