For backup and restore purposes, you can get the database/table dump and save it to a offline location. These backups can be useful to restore data that may be lost due to unforeseen circumstances. 

SYNTAX

shell> mariadb-dump -u -p -w --lock-all-tables --insert-ignore --no-create-info  (optional table name) >  <outputfilename>

EXAMPLE 1 (backup for the entire database)

shell> mariadb-dump -u root -p -w “sid=2” --lock-all-tables --insert-ignore --no-create-info skfs > skfsdata_backup.db  

EXAMPLE 2 (backup for a specific table)

shell> mariadb-dump -u root -p -w “sid=2” --lock-all-tables --insert-ignore --no-create-info skfs fido_keys > fidokeys_backup.db 

EXAMPLE 3 (backup for more than one table)

If you want to generate the back up for more than one table, you must separate the names of the tables with space.

shell> mariadb-dump -u root -p -w “sid=2” --lock-all-tables --insert-ignore --no-create-info skfs fido_keys fido_policies > fidokeys_policies_backup.db
