Split backup mysql user in seperate file

[svaroqui]

• Mysqldump --insert-ignore --system=user mysql users
• Myloader restore mysql table only with insert ignore of csv.gzip file and rename user table gzip files before restoring backup restore file after restore

[caffeinated92]

Correct syntax: Mysqldump --insert-ignore --system=user

I would rather improve on this with embedding mariadb >=11 .6 using https://mariadb.com/resources/blog/enhancements-to-mariadb-logical-dump-and-import-tools-in-release-series-11-5-11-6/ this would give:

• Consistency with mydumper getting a file per table
• Speedup using concurrent restore via mariadb-import
• Capability to have consistent backup with system tables and only restore system table on demand
