Encrypting Database Backups

Plan backup encryption. Keep the key out of the backup. Do not delete the only copy.

Updated 25 October 2026 · Checklist

This is an original planning guide. It is not a vendor manual, an official standard, or legal advice. Example addresses use documentation ranges. Review every command before you paste it.

What this hour is for

The planner asks where the key lives and whether the backup file would contain it. The key stays in the secret store. It does not go in the backup and it does not go in the note.

Do not delete the only unencrypted copy until a person has read an encrypted copy back. Do not turn encryption off. Do not run the backup during the reading.

192.0.2.10, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. example.com is a documentation name. A sample password is replaced. It is not a password you keep.

The change you can finish

Apply nothing while you are writing the note. When the lab window opens, it is one change on the database named in the ticket. Read the draft, then the database, then decide.

Rollback is the backup, the file, or the snapshot you saved first. You do not invent a rollback after the only copy is gone.

  1. Write where the key lives.
  2. Confirm the key is not in the backup file.
  3. Keep the only copy.
  4. Do not run the backup.
  5. Stop.

Mistakes that outlive the statement

Encrypting Database Backups goes wrong in a small set of ways. The list is here so the ticket can forbid them before the window.

Decisions to write down

One decision for Encrypting Database Backups: The key location is written. The key is not in the backup. The only copy remains. And encryption stays on.

Checks before you call it done

Confirm this before you call the change done: The database is written. The key location is written. The only copy remains. Nothing was run. And the database is yours. If one of those fails, stop.

Before you leave the database

Encrypting Database Backups ends when the database in the prompt is the database in the ticket. If it is not, you are on the wrong database. Stop.

The draft stays a draft until a person has read the names in it. A generator does not log into the database. You delete a line that names a host, a database, or an account you did not write down.

192.0.2.10, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. example.com is a documentation name. They belong in the note. They are not values you leave on a database because a draft included them.

prompt-for-this is a reminder that a secret is missing. It is not a password, a key, or a token you save in the ticket or in git. A sample password in a draft is replaced. It is not a password you keep.

One change is the window. If two things move and the result is wrong, you will not know which one did it.

If the same step fails twice, stop for the day. Restore the copy you took first.

A second person reads the database name and the change aloud. If they cannot find them in the ticket, the note is not done.
