Data Domain: DD BoostFS Plug-In Validation and Best Practices for MySQL my dumper
Sammendrag: This KB article provides best practices and configuration guidelines for applications with the Data Domain DD Boost File System Plug-In (BoostFS). In addition, this article contains insights and tips about how the application should be configured to maximize all the benefits of BoostFS. ...
Instruksjoner
My dumper is a free, open-source online backup tool for MySQL data that provides:
- Parallelism (hence, speed) and performance (avoids expensive character set conversion routines, efficient code overall)
- Easier to manage output (separate files for tables, dump metadata, and so on to view and parse data)
- Consistency: Maintains snapshots across all threads, provides accurate control and child log positions, so forth.
Set up BoostFS
Install BoostFS on the MySQL server to be backed up.
Create a mountpoint/backup and mount the DD Storage Unit using BoostFS.
Disable compression:
--compress/-c option
This enables output file compression during backup Disabled by default; if not specified on the CLI, compression remains off.
How to configure multiple streams.
This command enables multiple streams during backups or restores:
CLI option –threads (<64)
How to perform a backup.
/emc/src/mydumper/mydumper-0.9.1/mydumper --user=root --password=passwd --host=ostqa-len35.datadomain.com --port=3306 --
database db1 --threads=63 --outputdir /mounts/bfs/gen0
How to perform a restore.
/emc/src/mydumper/mydumper-0.9.1/myloader --user=root --password=passwd --host=ostqa-len35.datadomain.com --port=3306 --
threads=63 --directory=/mounts/bfs/gen1
How to configure multiple streams.
CLI option: Threads enable multiple streams during backup or restore as shown above.
Best Practices - MySQL Enterprise Backup
- Install my dumper on each MySQL server.
- Disable software compression and encryption for better data deduplication.
- Enable multiple streams for greater throughput.
- Multistream recovery is not supported.
- Up to 63 streams per BoostFS plug-in.
