Recovery guidelines

Follow these guidelines to ensure a safe recovery:

Always:

Include step-by-step instructions and checklists in the recovery plan.
Keep a hard copy of the recovery plan.
Back up the database on a regular basis.
Back up the AI files on different media from the database and BI files.
Label, test, and keep the backups in a separate and secure location.

Do Not:

Store a BI file on the same disk as an AI file.
Erase a DB, BI, or AI file unless you are certain you no longer want the database, or unless you have a secure, complete backup.
Copy a database file without also copying the BI files associated with that database.
Restore a database file without restoring the corresponding BI file.
Copy a database with an operating system utility while the database is in use without running PROQUIET.

Caution: If you run your OpenEdge database with the Unreliable Buffered I/O (-r) parameter and the system fails because of a system crash or power failure, you cannot recover the database. If you run with the No Crash Protection (-i) parameter and the database fails for any reason, you cannot recover the database.
