<p dir="auto">I recently begun mirroring my full backups to backblaze and I've been getting the error "maximum size allowed is (your minPartSize for the chunk)"</p>

<p dir="auto">This error was supposed to be fixed, earlier this year, but I'm still getting it.<br />
Actually  PR #9396 might only fix direct backups and not mirror backups...<br />
I'm running xo built last week. Object lock is set to 0 at backblaze for the time being, but I plan to turn it whenr this problem is over.</p>
<p dir="auto">This may be caused because I'm mirroring from a local nfs remote (not encripted) to backcblaze remote (encripted) ? Maybe this scenario wasn't tested.</p>

<p dir="auto">I've just bumped minPartSize to 100 000 000 (following the recomendation from Backblaze and hope that the maximum size allowed error goes away, though the warnings will still be there.</p>
<p dir="auto">Thank you,<br />
