DESCRIPTION         top

       Usage:

       Backup: set -o pipefail; myrocks_hotbackup --user=root
       --password=pw --port=3306 --checkpoint_dir=<directory where
       temporary backup hard links are created> | ssh -o NoneEnabled=yes
       remote_server 'tar -xi -C <directory on remote server where
       backups will be sent>' . You need to execute backup command on a
       server where you take backups.

       Backup using WDT: myrocks_hotbackup --user=root --password=pw
       --stream=wdt --checkpoint_dir=<directory where temporary backup
       hard links are created> --destination=<remote host name>
       --backup_dir=<remote directory name>. This has to be executed at
       the src host.

       Move-Back: myrocks_hotbackup --move_back --datadir=<dest mysql
       datadir> --rocksdb_datadir=<dest rocksdb datadir>
       --rocksdb_waldir=<dest rocksdb wal dir> --backup_dir=<where
       backup files are stored> . You need to execute move-back command
       on a server where backup files are sent.
