Description
On executing of
mariabackup --move-back --target-dir=.
|
mariabackup deletes the current sourcefile after an "No space left on device" error before exiting. Only the incomplete target file is still available.

After this the prepared backup is useless as at least one file is missing/incomplete.
mariabackup should delete the incomplete target file instead and allow a re-run of the process to complete the restore.
Also mariabackup should try to use a native filesystem move if on same filesystem instead of a copy/delete cycle to reduce required disk space during the restore step and the option --move-back.
