Hello

I try to copy a VM from an host to another host but I have some errors.
Lot of " Permission denied " and no files on new host.
Any idea ?

Thanxs a lot for your help

You can't just copy data from one server to another, you need to be athenticated.
To do so, link both servers by means of the --link-srv argument.

./xsibackup --link-srv=1.2.3.4:22

Or using the GUI: Exchange RSA keys thrugh the (c)XSIBackup-Pro Classic GUI

You also have an spurious unneded slash in your job.

I have already made the link with the remote server.
Ok for the double / in the job, I will correct it

Thank you

OpenSSH is throwing a clear error: Permission denied (publickey,keyboard-interactive)
You may believe to have linked both servers but you have not.

Now the next questions are:

- What is the other host?: OS, version...
- Is the other OpenSSH version compatible in KEX and cipher algorithms?.

Your ESXi system is 5.1, if the remote counterpart is too distant in main version number you would need to analyze what ciphers and KEX algorithms are in use in every system, just to determine whether setting some value manually can overcome your issue.

Make sure the xsibackup_id_rsa key is present at the remote server's authorized_keys file and run the below command from the (c)XSIBackup-Pro installation root.

ssh -vvv -i xsibackup_id_rsa root@x.x.x.x "echo HI"

It will show a verbose log that you can use to determine what the issue is.

(c)XSIBackup-Pro uses SSH to transfer data, it is as compatible for remote transfers as your systems at play are. If you get into complicated situations that require analyzing the SSH conversation and finding workarounds you depend on your own knowledge of general purpose Linux tools such as OpenSSH.

If you are trying to copy data from ESXi 5.1 to some new Linux distro or ESXi version, you will be hitting some cipher incompatibility issue. The easiest way to workaround the issue is to use some older Linux or ESXi version as the target that is indeed compatible with your current set of cipehrs and KEX. Or even easier, use some shared datastore that you can mount on both ESXi/ Linux hosts via NFS3.

Should you need some additional help, we can provide it as an additional consultancy service.

Please, note this thread corresponds to an old software edition - (c)XSIBackup Classic - which has been deprecated. Use our latest software edition: (c)XSIBackup-DC and refer to its manual to backup your (c)ESXi VMs as of 2021
