I use copy-back option in xtrabackup while doing a full data restore.
For copy-back option to execute successfully, the data directory should be empty.
Why cant I use the same copy-back option while doing a restore of partial backups instead of manually copying the .* files to the data directory?
May I know the limitations of copy-back option and why cant I use it for partial backups as copy-backup option copies the files from the backup directory to the data directory only.
