Does JetBackup lock tables when it performs MySql Backups?

JetBackup uses "mysqldump" to export the databases.

There are several flags in which you can set as desired:

  • Max allowed packets
  • force flag
  • opt flag
  • skip lock table
  • single transaction flag

These settings could be found under your MySQL Database Connection Settings.

mysql database connection

So to make sure mysqldump will lock tables, you need to uncheck the "skip-lock" flag in there.
