Backup restoration

I have Openemr 6.0.0 installed in a virtual Centos server and I’m trying to test the backup function. I have created the backup file (emr_backup.tar) but restoring it on another Centos server has been difficult. The sudo ./restore command described on the openemr documenation page appears not to work on Centos. Can someone help me with this?
Thanks
