I try to backup esxi via rsync over ssh. I run rsyc but I get error:

# rsync -e ssh -av root@ip.esxi:file.txt .
sh: rsync: not found
rsync: connection unexpectedly closed (0 bytes received so far) [receiver]
rsync error: error in rsync protocol data stream (code 12) at io.c(635) [receiver=3.0.3]

If I connect with ssh/scp everything is fine.

You need rsync on your ESXi. You can get a binary here.

The rsync command is not part of the default ESXi installation. ESXi uses a modified version of Busybox to provide a limited subset of Linux commands on the console. That's why rsync isn't available. While it's possible to dump a statically-compiled rsync binary onto an ESXi host, this is not the way to handle backups with VMware.

You can use scp, however.

There are better tools for VMware backups and handling virtual machines, though.

rsync is not installed, or not installed in a location that is in your $PATH on the remote side

I not run rsync on esxi but linux server. The remote server (esxi in this case) not need installed rsync but ssh only. – amiad Oct 31 '13 at 12:24
yes, it has to be installed on both machines. – Javier Oct 31 '13 at 13:55
