Hi, for me the issue appeared with version 2.1 of percona-wtrabackup on debian.
With version 2.0 i had this warning message, and backup was done :
```auto
xtrabackup_55: ambiguous option '--log=/var/log/mysql/mysql.log' (log-copy-interval, log-stream)
```
With version 2.1 this is not a warning message, but and error message, and backup is not done:
```auto
Unknown suffix '/' used for variable 'log-copy-interval' (value '/var/log/mysql/mysql.log')
xtrabackup_55: Error while setting value '/var/log/mysql/mysql.log' to 'log-copy-interval'
```

The “log” option in /etc/my.cnf is deprecated, use [general\_log](https://kb.askmonty.org/en/server-system-variables/#general_log) instead. See: [URL][Server System Variables - MariaDB Knowledge Base](https://kb.askmonty.org/en/server-system-variables/#log%5B/URL%5D)
BTW for old servers for which “log” is the correct way to set it up:
innobackupex: Error: Support for MySQL 5.1 with builtin InnoDB (not the plugin) was removed in Percona XtraBackup 2.1. The last version to support MySQL 5.1 with builtin InnoDB was Percona XtraBackup 2.0. at /usr/bin/innobackupex line 389.
