You are creating a strategy for backing up MySQL using a cold binary backup. The MySQL instance is a replication master with global transaction identifiers (GTIDs) enabled and it uses Transparent Data Encryption (TDE). Other than the configuration required to make the instance a replication master and enabled GTIDs and TDE, the instance is using all default settings.
The requirements for the backup are:
- It must be possible to rebuild the instance using the backup.
- It must be verified.
- It must allow for a catastrophic hardware failure.
Which four steps must be included in the backup strategy? (Choose four.)
- A. Include the keyring data and/or configuration in the backup.
- B. Include the MySQL socket file in the backup.
- C. Restore the backup to a clean MySQL instance.
- D. Include the relay logs in the backup.
- E. Include the binary logs in the backup.
- F. Copy the backup to a remote host.
- G. Include the MySQL PID file in the backup.
- H. Include the ibtmp1 file in the backup.
- I. Include the operating system disk encryption key in the backup.
Correct Answer: D,F,G,I 🗳️
