SHA1 chunk hashes check failed error

I get this error: "SHA1 chunk hashes check failed error "  when doing a backup on VMware ESXi 6.5.0 with --backup-point set to another Vmware ESXi 6.5.0 via ssh and --certify-backup=yes. xsibackup-pro is installed on both machines. How to troubleshoot this problem?

Re: SHA1 chunk hashes check failed error

It can be due to many different reasons, we need more detail. Contact support to provide the full log and backup job.

Re: SHA1 chunk hashes check failed error

(c)XSIBackup-Classic has been deprecated.
Your version is not even the latest one available, you should upgrade.
You have not published your job nor the output, just one error.
This does not seem to be an XSITools related error but an Rsync replica related one.
Without all the details on your job and output there is very little that we can do to help you but to make asumptions and offer general advice.

Asuming that this is indeed an Rsync replica and that you have used the --certify-backup option to compare checksums on both ends, you should read this post, it is rather generic and can be used to comprehend how you should interpret a hash mismatch.
