    Description

      test scenarion:

      1. create one table, make first backup

      sudo mariadb-backup -utest_user -p**** --backup --target-dir=backup/base_backup_dir

      2. create second table, create next part of backup:
      sudo mariadb-backup -utest_user -p**** --backup --incremental-basedir=backup/base_backup_dir --target-dir=backup/inc_backup_dir_2

      repeat it several times

      3. clean DB directory, start backup prepare:

      sudo mariadb-backup --prepare --target-dir=backup_prepare/base_backup_dir
      sudo mariadb-backup --prepare --target-dir=backup_prepare/base_backup_dir --incremental-dir=backup_prepare/inc_backup_dir_2
      sudo mariadb-backup --prepare --target-dir=backup_prepare/base_backup_dir --incremental-dir=backup_prepare/inc_backup_dir_3

      the last command fails:

      sudo mariadb-backup --prepare --target-dir=backup_prepare/base_backup_dir --incremental-dir=backup_prepare/inc_backup_dir_3
