what is in "aria_log.00000001" and "aria_log_control" and can i
skip them from backups? as far as i see they don't contain any
really needed informations

It is transaction log files, as well as some parameters (block size).

Transaction log used in recovery, so in normal server start if there is database but no transaction files something went wrong and we can't check integrity.

Probably recovery can restore the files, but normal server start have to fail on damaged files.

* so can i exclude that files completly from backups
* could MariaDB delete them instead of refuse to start
   in case the are damaged?

see my last comment on the following bugreport
