xtrabackup --move-back fails with "cannot open file" error

Hello guys, 

I hope not to ask something too obvious, but I can’t find anything that can help me with my problem. I have tried to make a Master/Slave test server with https://www.percona.com/doc/percona-xtrabackup/2.3/howtos/setting_up_replication.html as a guide but I’m stuck at the second step, move-back command.  When I run “xtrabackup --move-back --target-dir=/home/cmihai/mysql_xtrabackup” command, i receive:  

I already check the version of xtrabackupserver and it is the same on both servers. I guess it’s a rights issue but I haven’t found anything concrete on the internet, and the rights are given on root, the same user I’m logged in to when I run the command

Hi @Fatidic
I would suggest you to try Percona XtraBackup 8.0.
Percona XtraBackup 2.4 does not support making backups of databases created in MySQL 8.0, Percona Server for MySQL 8.0 or Percona XtraDB Cluster 8.0.
