Backup All Databases

MySQL-Bkup supports backing up all databases on the server using the --all-databases (-a) flag. By default, this creates separate backup files for each database. If you prefer a single backup file, you can use the --all-in-one (-A) flag.

Backing up all databases is useful for creating a snapshot of the entire database server, whether for disaster recovery or migration purposes.

Backup Modes

Separate Backup Files (Default)

Using --all-databases without --all-in-one creates individual backup files for each database.

• Creates separate backup files for each database.
• Provides more flexibility in restoring individual databases or tables.
• Can be more manageable in cases where different databases have different retention policies.
• Might take slightly longer due to multiple file operations.
• It is the default behavior when using the --all-databases flag.
• It does not backup system databases (information_schema, performance_schema, mysql, sys, innodb).

Command:

docker run --rm --network your_network_name \
  -v $PWD/backup:/backup/ \
  -e "DB_HOST=dbhost" \
  -e "DB_PORT=3306" \
  -e "DB_USERNAME=username" \
  -e "DB_PASSWORD=password" \
  jkaninda/mysql-bkup backup --all-databases

Single Backup File

Using --all-in-one (-A) creates a single backup file containing all databases.

• Creates a single backup file containing all databases.
• Easier to manage if you need to restore everything at once.
• Faster to back up and restore in bulk.
• Can be problematic if you only need to restore a specific database or table.
• It is recommended to use this option for disaster recovery purposes.
• It backups system databases as well.

docker run --rm --network your_network_name \
  -v $PWD/backup:/backup/ \
  -e "DB_HOST=dbhost" \
  -e "DB_PORT=3306" \
  -e "DB_USERNAME=username" \
  -e "DB_PASSWORD=password" \
  jkaninda/mysql-bkup backup --all-in-one

When to Use Which?

• Use --all-in-one if you want a quick, simple backup for disaster recovery where you'll restore everything at once.
• Use --all-databases if you need granularity in restoring specific databases or tables without affecting others.
