The 'mysqlbackup' command to perform a restore operation is . . . . . . . .

Solution (By Examveda Team)

This question asks about how the 'mysqlbackup' command works when you want to restore a MySQL database.
Let's break down the options:
Option A: copy-back-and-apply-log This means that the backup files are copied back to the original location, and then the transaction logs are applied to bring the database to the latest state.
Option B: apply-log-and-copy-back This option suggests that the transaction logs are applied first, and then the backup files are copied back.
Option C: copy-log-and-apply-back This option doesn't make sense in the context of database restoration. It suggests copying the log files and then applying them back to the original database.
Option D: apply-back-and-copy-log This option doesn't follow the standard restore procedure. It suggests applying the backup first, then copying the log files back.
The correct answer is Option A: copy-back-and-apply-log. This is the standard process for restoring a MySQL database using 'mysqlbackup' command. The backup files are restored first, and then the transaction logs are applied to ensure the database is updated to the latest state.
