I try to backup running (with no problem) MySQL instance, but percona hits error below which I can not overcome and do not understand the reason. Looks like InnoDB engine can not find it is own log… Can some one help please? Any ideas?

Do you mean xtrabackup works for stock MySQL but fails on Percona Server ? Please send us the contents of my.cnf file and xtrabackup version you are using. $ xtrabackup --version ---

Interesting fact - my-dbtuna.cnf (the my.cnf for the instance) does not have “datadir” parameter. Can that be the problem?

Declare datadir in my.cnf and restart mysql and try again.
