Описание (Description)

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.
