- when you take regular btrfs-snapshots to a remote system, the
location of the remote "backup_root" is saved as parameter SUBVOLUME
in the constucted snapper-config.
In case you need to make a interactive backup/clone to a different
target, the commandline options need to have priority, thus
overriding the SUBVOLUME default.
- in verbose mode, show the result of the constructed backupdir and backup_root

- on slow systems, multiple ssh calls in a row might fail without a
suitable timegap. To overcome this, a short sleep doesn't hurt.

* be verbose, if requested
* handle return codes for function call
* to re-format an already partitioned tape, its need to be wiped first
* just simply removing data from tape does not free the occupied space
thus, we need to wipe it and format again to get full capacity of
the tape
