# proxmox-backup-client backup archive.pxar:/etc/hostname --repository 'backup@pbs!pbs-client-test@pbs-server.test.local:localrepo'
Error: got unexpected file type (expected directory)/etc directory with the above command works fine.
NAME.pxar:/etc/hostname you'd need to use NAME.img:/etc/hostname, or, for small files, NAME.conf:/etc/hostname (the last one is not chunked at all, but stored as-is in the snapshot dir as "blob", like the guest/firewall configs are in case of a PVE CT/VM backup).
--exclude options. Should these not be clearly explained in the Backup Client Usage page?

--backup-id "${HOSTNAME_SHORT}"Hi @fabian, thanks for the reply. That right there is another very important piece of information that could be made explicit in the docs as well.
